# kpod - Simple debugging tool for pods and images
|
||||
kpod is a simple client only tool to help with debugging issues when daemons such as CRI runtime and the kubelet are not responding or
|
||||
failing. A shared API layer could be created to share code between the daemon and kpod. kpod does not require any daemon running. kpod
|
||||
utilizes the same underlying components that crio uses i.e. containers/image, container/storage, oci-runtime-tool/generate, runc or
|
||||
any other OCI compatible runtime. kpod shares state with crio and so has the capability to debug pods/images created by crio.
|
||||
|
||||
## Use cases
|
||||
1. List pods.
|
||||
2. Launch simple pods (that require no daemon support).
|
||||
3. Exec commands in a container in a pod.
|
||||
4. Launch additional containers in a pod.
|
||||
5. List images.
|
||||
6. Remove images not in use.
|
||||
7. Pull images.
|
||||
8. Check image size.
|
||||
9. Report pod disk resource usage.

% Dan Walsh

# kpod-attach "1" "September 2017" "kpod"
|

|

## NAME
|
||||
kpod-attach - Attach to a running container
|
||||
|
||||
## Description
|
||||
|
||||
We chose not to implement the `attach` feature in `kpod` even though the upstream Docker
|
||||
project has it. The upstream project has had lots of issues with attaching to running
|
||||
processes that we did not want to replicate. The `kpod exec` and `kpod log` commands
|
||||
offer you the same functionality far more dependably.
|
||||
|
||||
**Reasons to attach to the primary PID of a container:**
|
||||
|
||||
|
||||
1) Executing commands inside of the container
|
||||
|
||||
We recommend that you use `kpod exec` to execute a command within a container
|
||||
|
||||
`kpod exec CONTAINERID /bin/sh`
|
||||
|
||||
2) Viewing the output stream of the primary process in the container
|
||||
|
||||
We recommend that you use `kpod logs` to see the output from the container
|
||||
|
||||
`kpod logs CONTAINERID`

% kpod(1) kpod-cp - Copy content between container's file system and the host

% Dan Walsh
|

# kpod-cp "1" "August 2017" "kpod"
|
||||
|
||||
## NAME
|
||||
kpod-cp - Copy files/folders between a container and the local filesystem.
|
||||
|
||||
## Description
|
||||
We chose not to implement the `cp` feature in `kpod` even though the upstream Docker
|
||||
project has it. We have a much stronger capability. Using standard kpod-mount
|
||||
and kpod-umount, we can take advantage of the entire linux tool chain, rather
|
||||
then just cp.
|
||||
|
||||
If a user wants to copy contents out of a container or into a container, they
|
||||
can execute a few simple commands.
|
||||
|
||||
You can copy from the container's file system to the local machine or the
|
||||
reverse, from the local filesystem to the container.
|
||||
|
||||
If you want to copy the /etc/foobar directory out of a container and onto /tmp
|
||||
on the host, you could execute the following commands:
|
||||
|
||||
mnt=$(kpod mount CONTAINERID)
|
||||
cp -R ${mnt}/etc/foobar /tmp
|
||||
kpod umount CONTAINERID
|
||||
|
||||
If you want to untar a tar ball into a container, you can execute these commands:
|
||||
|
||||
mnt=$(kpod mount CONTAINERID)
|
||||
tar xf content.tgz -C ${mnt}
|
||||
kpod umount CONTAINERID
|
||||
|
||||
One last example, if you want to install a package into a container that
|
||||
does not have dnf installed, you could execute something like:
|
||||
|
||||
mnt=$(kpod mount CONTAINERID)
|
||||
dnf install --installroot=${mnt} httpd
|
||||
chroot ${mnt} rm -rf /var/log/dnf /var/cache/dnf
|
||||
kpod umount CONTAINERID
|
||||
|
||||
This shows that using `kpod mount` and `kpod umount` you can use all of the
|
||||
standard linux tools for moving files into and out of containers, not just
|
||||
the cp command.

% Dan Walsh
|

kpod-create - Create a new container
|
||||
|
||||
# SYNOPSIS
|
||||
**kpod create** [*options* [...]] IMAGE [COMMAND] [ARG...]
|
||||
|
||||
# DESCRIPTION
|
||||
|
||||
Creates a writeable container layer over the specified image and prepares it for
|
||||
running the specified command. The container ID is then printed to STDOUT. This
|
||||
is similar to **kpod run -d** except the container is never started. You can
|
||||
then use the **kpod start <container_id>** command to start the container at
|
||||
any point.
|
||||
|
||||
The initial status of the container created with **kpod create** is 'created'.
|
||||
|
||||
# OPTIONS
|
||||
**--add-host**=[]
|
||||
Add a custom host-to-IP mapping (host:ip)
|
||||
|
||||
Add a line to /etc/hosts. The format is hostname:ip. The **--add-host**
|
||||
option can be set multiple times.
|
||||
|
||||
**-a**, **--attach**=[]
|
||||
Attach to STDIN, STDOUT or STDERR.
|
||||
|
||||
In foreground mode (the default when **-d**
|
||||
is not specified), **kpod run** can start the process in the container
|
||||
and attach the console to the process's standard input, output, and standard
|
||||
error. It can even pretend to be a TTY (this is what most commandline
|
||||
executables expect) and pass along signals. The **-a** option can be set for
|
||||
each of stdin, stdout, and stderr.
|
||||
|
||||
**--blkio-weight**=*0*
|
||||
Block IO weight (relative weight) accepts a weight value between 10 and 1000.
|
||||
|
||||
**--blkio-weight-device**=[]
|
||||
Block IO weight (relative device weight, format: `DEVICE_NAME:WEIGHT`).
|
||||
|
||||
**--cap-add**=[]
|
||||
Add Linux capabilities
|
||||
|
||||
**--cap-drop**=[]
|
||||
Drop Linux capabilities
|
||||
|
||||
**--cgroup-parent**=""
|
||||
Path to cgroups under which the cgroup for the container will be created. If the path is not absolute, the path is considered to be relative to the cgroups path of the init process. Cgroups will be created if they do not already exist.
|
||||
|
||||
**--cidfile**=""
|
||||
Write the container ID to the file
|
||||
|
||||
**--cpu-count**=*0*
|
||||
Limit the number of CPUs available for execution by the container.
|
||||
|
||||
On Windows Server containers, this is approximated as a percentage of total CPU usage.
|
||||
|
||||
On Windows Server containers, the processor resource controls are mutually exclusive, the order of precedence is CPUCount first, then CPUShares, and CPUPercent last.
|
||||
|
||||
**--cpu-period**=*0*
|
||||
Limit the CPU CFS (Completely Fair Scheduler) period
|
||||
|
||||
Limit the container's CPU usage. This flag tell the kernel to restrict the container's CPU usage to the period you specify.
|
||||
|
||||
**--cpu-quota**=*0*
|
||||
Limit the CPU CFS (Completely Fair Scheduler) quota
|
||||
|
||||
Limit the container's CPU usage. By default, containers run with the full
|
||||
CPU resource. This flag tell the kernel to restrict the container's CPU usage
|
||||
to the quota you specify.
|
||||
|
||||
**--cpu-rt-period**=0
|
||||
Limit the CPU real-time period in microseconds
|
||||
|
||||
Limit the container's Real Time CPU usage. This flag tell the kernel to restrict the container's Real Time CPU usage to the period you specify.
|
||||
|
||||
**--cpu-rt-runtime**=0
|
||||
Limit the CPU real-time runtime in microseconds
|
||||
|
||||
Limit the containers Real Time CPU usage. This flag tells the kernel to limit the amount of time in a given CPU period Real Time tasks may consume. Ex:
|
||||
Period of 1,000,000us and Runtime of 950,000us means that this container could consume 95% of available CPU and leave the remaining 5% to normal priority tasks.
|
||||
|
||||
The sum of all runtimes across containers cannot exceed the amount allotted to the parent cgroup.
|
||||
|
||||
**--cpu-shares**=*0*
|
||||
CPU shares (relative weight)
|
||||
|
||||
By default, all containers get the same proportion of CPU cycles. This proportion
|
||||
can be modified by changing the container's CPU share weighting relative
|
||||
to the weighting of all other running containers.
|
||||
|
||||
To modify the proportion from the default of 1024, use the **--cpu-shares**
|
||||
flag to set the weighting to 2 or higher.
|
||||
|
||||
The proportion will only apply when CPU-intensive processes are running.
|
||||
When tasks in one container are idle, other containers can use the
|
||||
left-over CPU time. The actual amount of CPU time will vary depending on
|
||||
the number of containers running on the system.
|
||||
|
||||
For example, consider three containers, one has a cpu-share of 1024 and
|
||||
two others have a cpu-share setting of 512. When processes in all three
|
||||
containers attempt to use 100% of CPU, the first container would receive
|
||||
50% of the total CPU time. If you add a fourth container with a cpu-share
|
||||
of 1024, the first container only gets 33% of the CPU. The remaining containers
|
||||
receive 16.5%, 16.5% and 33% of the CPU.
|
||||
|
||||
On a multi-core system, the shares of CPU time are distributed over all CPU
|
||||
cores. Even if a container is limited to less than 100% of CPU time, it can
|
||||
use 100% of each individual CPU core.
|
||||
|
||||
For example, consider a system with more than three cores. If you start one
|
||||
container **{C0}** with **-c=512** running one process, and another container
|
||||
**{C1}** with **-c=1024** running two processes, this can result in the following
|
||||
division of CPU shares:
|
||||
|
||||
PID container CPU CPU share
|
||||
100 {C0} 0 100% of CPU0
|
||||
101 {C1} 1 100% of CPU1
|
||||
102 {C1} 2 100% of CPU2
|
||||
|
||||
**--cpus**=0.0
|
||||
Number of CPUs. The default is *0.0* which means no limit.
|
||||
|
||||
**--cpuset-cpus**=""
|
||||
CPUs in which to allow execution (0-3, 0,1)
|
||||
|
||||
**--cpuset-mems**=""
|
||||
Memory nodes (MEMs) in which to allow execution (0-3, 0,1). Only effective on NUMA systems.
|
||||
|
||||
If you have four memory nodes on your system (0-3), use `--cpuset-mems=0,1`
|
||||
then processes in your container will only use memory from the first
|
||||
two memory nodes.
|
||||
|
||||
**-d**, **--detach**=*true*|*false*
|
||||
Detached mode: run the container in the background and print the new container ID. The default is *false*.
|
||||
|
||||
At any time you can run **kpod ps** in
|
||||
the other shell to view a list of the running containers. You can reattach to a
|
||||
detached container with **kpod attach**. If you choose to run a container in
|
||||
the detached mode, then you cannot use the **-rm** option.
|
||||
|
||||
When attached in the tty mode, you can detach from the container (and leave it
|
||||
running) using a configurable key sequence. The default sequence is `CTRL-p CTRL-q`.
|
||||
You configure the key sequence using the **--detach-keys** option or a configuration file.
|
||||
See **config-json(5)** for documentation on using a configuration file.
|
||||
|
||||
**--detach-keys**=""
|
||||
Override the key sequence for detaching a container. Format is a single character `[a-Z]` or `ctrl-<value>` where `<value>` is one of: `a-z`, `@`, `^`, `[`, `,` or `_`.
|
||||
|
||||
**--device**=[]
|
||||
Add a host device to the container (e.g. --device=/dev/sdc:/dev/xvdc:rwm)
|
||||
|
||||
**--device-read-bps**=[]
|
||||
Limit read rate (bytes per second) from a device (e.g. --device-read-bps=/dev/sda:1mb)
|
||||
|
||||
**--device-read-iops**=[]
|
||||
Limit read rate (IO per second) from a device (e.g. --device-read-iops=/dev/sda:1000)
|
||||
|
||||
**--device-write-bps**=[]
|
||||
Limit write rate (bytes per second) to a device (e.g. --device-write-bps=/dev/sda:1mb)
|
||||
|
||||
**--device-write-iops**=[]
|
||||
Limit write rate (IO per second) to a device (e.g. --device-write-iops=/dev/sda:1000)
|
||||
|
||||
**--dns**=[]
|
||||
Set custom DNS servers
|
||||
|
||||
This option can be used to override the DNS
|
||||
configuration passed to the container. Typically this is necessary when the
|
||||
host DNS configuration is invalid for the container (e.g., 127.0.0.1). When this
|
||||
is the case the **--dns** flags is necessary for every run.
|
||||
|
||||
**--dns-option**=[]
|
||||
Set custom DNS options
|
||||
|
||||
**--dns-search**=[]
|
||||
Set custom DNS search domains (Use --dns-search=. if you don't wish to set the search domain)
|
||||
|
||||
**--entrypoint**=""
|
||||
Overwrite the default ENTRYPOINT of the image
|
||||
|
||||
This option allows you to overwrite the default entrypoint of the image.
|
||||
The ENTRYPOINT of an image is similar to a COMMAND
|
||||
because it specifies what executable to run when the container starts, but it is
|
||||
(purposely) more difficult to override. The ENTRYPOINT gives a container its
|
||||
default nature or behavior, so that when you set an ENTRYPOINT you can run the
|
||||
container as if it were that binary, complete with default options, and you can
|
||||
pass in more options via the COMMAND. But, sometimes an operator may want to run
|
||||
something else inside the container, so you can override the default ENTRYPOINT
|
||||
at runtime by using a **--entrypoint** and a string to specify the new
|
||||
ENTRYPOINT.
|
||||
|
||||
**-e**, **--env**=[]
|
||||
Set environment variables
|
||||
|
||||
This option allows you to specify arbitrary
|
||||
environment variables that are available for the process that will be launched
|
||||
inside of the container.
|
||||
|
||||
**--env-file**=[]
|
||||
Read in a line delimited file of environment variables
|
||||
|
||||
**--expose**=[]
|
||||
Expose a port, or a range of ports (e.g. --expose=3300-3310) to set up port redirection
|
||||
on the host system.
|
||||
|
||||
**--group-add**=[]
|
||||
Add additional groups to run as
|
||||
|
||||
**--hostname**=""
|
||||
Container host name
|
||||
|
||||
Sets the container host name that is available inside the container.
|
||||
|
||||
**--help**
|
||||
Print usage statement
|
||||
|
||||
**-i**, **--interactive**=*true*|*false*
|
||||
Keep STDIN open even if not attached. The default is *false*.
|
||||
|
||||
**--ip**=""
|
||||
Sets the container's interface IPv4 address (e.g. 172.23.0.9)
|
||||
|
||||
It can only be used in conjunction with **--network** for user-defined networks
|
||||
|
||||
**--ip6**=""
|
||||
Sets the container's interface IPv6 address (e.g. 2001:db8::1b99)
|
||||
|
||||
It can only be used in conjunction with **--network** for user-defined networks
|
||||
|
||||
**--ipc**=""
|
||||
Default is to create a private IPC namespace (POSIX SysV IPC) for the container
|
||||
'container:<name|id>': reuses another container shared memory, semaphores and message queues
|
||||
'host': use the host shared memory,semaphores and message queues inside the container. Note: the host mode gives the container full access to local shared memory and is therefore considered insecure.
|
||||
|
||||
**--kernel-memory**=""
|
||||
Kernel memory limit (format: `<number>[<unit>]`, where unit = b, k, m or g)
|
||||
|
||||
Constrains the kernel memory available to a container. If a limit of 0
|
||||
is specified (not using `--kernel-memory`), the container's kernel memory
|
||||
is not limited. If you specify a limit, it may be rounded up to a multiple
|
||||
of the operating system's page size and the value can be very large,
|
||||
millions of trillions.
|
||||
|
||||
**-l**, **--label**=[]
|
||||
Add metadata to a container (e.g., --label com.example.key=value)
|
||||
|
||||
**--label-file**=[]
|
||||
Read in a line delimited file of labels
|
||||
|
||||
**--link-local-ip**=[]
|
||||
Add one or more link-local IPv4/IPv6 addresses to the container's interface
|
||||
|
||||
**--log-driver**="*json-file*|*syslog*|*journald*|*gelf*|*fluentd*|*awslogs*|*splunk*|*etwlogs*|*gcplogs*|*none*"
|
||||
Logging driver for the container. Default is defined by daemon `--log-driver` flag.
|
||||
**Warning**: the `kpod logs` command works only for the `json-file` and
|
||||
`journald` logging drivers.
|
||||
|
||||
**--log-opt**=[]
|
||||
Logging driver specific options.
|
||||
|
||||
**--mac-address**=""
|
||||
Container MAC address (e.g. 92:d0:c6:0a:29:33)
|
||||
|
||||
Remember that the MAC address in an Ethernet network must be unique.
|
||||
The IPv6 link-local address will be based on the device's MAC address
|
||||
according to RFC4862.
|
||||
|
||||
**-m**, **--memory**=""
|
||||
Memory limit (format: <number>[<unit>], where unit = b, k, m or g)
|
||||
|
||||
Allows you to constrain the memory available to a container. If the host
|
||||
supports swap memory, then the **-m** memory setting can be larger than physical
|
||||
RAM. If a limit of 0 is specified (not using **-m**), the container's memory is
|
||||
not limited. The actual limit may be rounded up to a multiple of the operating
|
||||
system's page size (the value would be very large, that's millions of trillions).
|
||||
|
||||
**--memory-reservation**=""
|
||||
Memory soft limit (format: <number>[<unit>], where unit = b, k, m or g)
|
||||
|
||||
After setting memory reservation, when the system detects memory contention
|
||||
or low memory, containers are forced to restrict their consumption to their
|
||||
reservation. So you should always set the value below **--memory**, otherwise the
|
||||
hard limit will take precedence. By default, memory reservation will be the same
|
||||
as memory limit.
|
||||
|
||||
**--memory-swap**="LIMIT"
|
||||
A limit value equal to memory plus swap. Must be used with the **-m**
|
||||
(**--memory**) flag. The swap `LIMIT` should always be larger than **-m**
|
||||
(**--memory**) value. By default, the swap `LIMIT` will be set to double
|
||||
the value of --memory.
|
||||
|
||||
The format of `LIMIT` is `<number>[<unit>]`. Unit can be `b` (bytes),
|
||||
`k` (kilobytes), `m` (megabytes), or `g` (gigabytes). If you don't specify a
|
||||
unit, `b` is used. Set LIMIT to `-1` to enable unlimited swap.
|
||||
|
||||
**--memory-swappiness**=""
|
||||
Tune a container's memory swappiness behavior. Accepts an integer between 0 and 100.
|
||||
|
||||
**--name**=""
|
||||
Assign a name to the container
|
||||
|
||||
The operator can identify a container in three ways:
|
||||
UUID long identifier (“f78375b1c487e03c9438c729345e54db9d20cfa2ac1fc3494b6eb60872e74778”)
|
||||
UUID short identifier (“f78375b1c487”)
|
||||
Name (“jonah”)
|
||||
|
||||
kpod generates a UUID for each container, and if a name is not assigned
|
||||
to the container with **--name** then the daemon will also generate a random
|
||||
string name. The name is useful when defining links (see **--link**) (or any
|
||||
other place you need to identify a container). This works for both background
|
||||
and foreground containers.
|
||||
|
||||
**--network**="*bridge*"
|
||||
Set the Network mode for the container
|
||||
'bridge': create a network stack on the default bridge
|
||||
'none': no networking
|
||||
'container:<name|id>': reuse another container's network stack
|
||||
'host': use the kpod host network stack. Note: the host mode gives the container full access to local system services such as D-bus and is therefore considered insecure.
|
||||
'<network-name>|<network-id>': connect to a user-defined network
|
||||
|
||||
**--network-alias**=[]
|
||||
Add network-scoped alias for the container
|
||||
|
||||
**--oom-kill-disable**=*true*|*false*
|
||||
Whether to disable OOM Killer for the container or not.
|
||||
|
||||
**--oom-score-adj**=""
|
||||
Tune the host's OOM preferences for containers (accepts -1000 to 1000)
|
||||
|
||||
**--pid**=""
|
||||
Set the PID mode for the container
|
||||
Default is to create a private PID namespace for the container
|
||||
'container:<name|id>': join another container's PID namespace
|
||||
'host': use the host's PID namespace for the container. Note: the host mode gives the container full access to local PID and is therefore considered insecure.
|
||||
|
||||
**--pids-limit**=""
|
||||
Tune the container's pids limit. Set `-1` to have unlimited pids for the container.
|
||||
|
||||
**--pod**=""
|
||||
Run container in an existing pod
|
||||
|
||||
**--privileged**=*true*|*false*
|
||||
Give extended privileges to this container. The default is *false*.
|
||||
|
||||
By default, kpod containers are
|
||||
“unprivileged” (=false) and cannot, for example, modify parts of the kernel.
|
||||
This is because by default a container is not allowed to access any devices.
|
||||
A “privileged” container is given access to all devices.
|
||||
|
||||
When the operator executes **kpod run --privileged**, kpod enables access
|
||||
to all devices on the host as well as set turn off most of the security messurs
|
||||
protecting the host from the container.
|
||||
|
||||
**-p**, **--publish**=[]
|
||||
Publish a container's port, or range of ports, to the host
|
||||
|
||||
Format: `ip:hostPort:containerPort | ip::containerPort | hostPort:containerPort | containerPort`
|
||||
Both hostPort and containerPort can be specified as a range of ports.
|
||||
When specifying ranges for both, the number of container ports in the range must match the number of host ports in the range.
|
||||
(e.g., `kpod run -p 1234-1236:1222-1224 --name thisWorks -t busybox`
|
||||
but not `kpod run -p 1230-1236:1230-1240 --name RangeContainerPortsBiggerThanRangeHostPorts -t busybox`)
|
||||
With ip: `kpod run -p 127.0.0.1:$HOSTPORT:$CONTAINERPORT --name CONTAINER -t someimage`
|
||||
Use `kpod port` to see the actual mapping: `kpod port CONTAINER $CONTAINERPORT`
|
||||
|
||||
**-P**, **--publish-all**=*true*|*false*
|
||||
Publish all exposed ports to random ports on the host interfaces. The default is *false*.
|
||||
|
||||
When set to true publish all exposed ports to the host interfaces. The
|
||||
default is false. If the operator uses -P (or -p) then kpod will make the
|
||||
exposed port accessible on the host and the ports will be available to any
|
||||
client that can reach the host. When using -P, kpod will bind any exposed
|
||||
port to a random port on the host within an *ephemeral port range* defined by
|
||||
`/proc/sys/net/ipv4/ip_local_port_range`. To find the mapping between the host
|
||||
ports and the exposed ports, use `kpod port`.
|
||||
|
||||
**--read-only**=*true*|*false*
|
||||
Mount the container's root filesystem as read only.
|
||||
|
||||
By default a container will have its root filesystem writable allowing processes
|
||||
to write files anywhere. By specifying the `--read-only` flag the container will have
|
||||
its root filesystem mounted as read only prohibiting any writes.
|
||||
|
||||
**--rm**=*true*|*false*
|
||||
Automatically remove the container when it exits. The default is *false*.
|
||||
`--rm` flag can work together with `-d`, and auto-removal will be done on daemon side. Note that it's
|
||||
incompatible with any restart policy other than `none`.
|
||||
|
||||
**--security-opt**=[]
|
||||
Security Options
|
||||
|
||||
|
||||
"label=user:USER" : Set the label user for the container
|
||||
"label=role:ROLE" : Set the label role for the container
|
||||
"label=type:TYPE" : Set the label type for the container
|
||||
"label=level:LEVEL" : Set the label level for the container
|
||||
"label=disable" : Turn off label confinement for the container
|
||||
"no-new-privileges" : Disable container processes from gaining additional privileges
|
||||
|
||||
"seccomp=unconfined" : Turn off seccomp confinement for the container
|
||||
"seccomp=profile.json : White listed syscalls seccomp Json file to be used as a seccomp filter
|
||||
|
||||
"apparmor=unconfined" : Turn off apparmor confinement for the container
|
||||
"apparmor=your-profile" : Set the apparmor confinement profile for the container
|
||||
|
||||
**--shm-size**=""
|
||||
Size of `/dev/shm`. The format is `<number><unit>`. `number` must be greater than `0`.
|
||||
Unit is optional and can be `b` (bytes), `k` (kilobytes), `m`(megabytes), or `g` (gigabytes).
|
||||
If you omit the unit, the system uses bytes. If you omit the size entirely, the system uses `64m`.
|
||||
|
||||
**--sig-proxy**=*true*|*false*
|
||||
Proxy received signals to the process (non-TTY mode only). SIGCHLD, SIGSTOP, and SIGKILL are not proxied. The default is *true*.
|
||||
|
||||
**--stop-signal**=*SIGTERM*
|
||||
Signal to stop a container. Default is SIGTERM.
|
||||
|
||||
**--stop-timeout**=*10*
|
||||
Timeout (in seconds) to stop a container. Default is 10.
|
||||
|
||||
**--storage-opt**=[]
|
||||
Storage driver options per container
|
||||
|
||||
$ kpod create -it --storage-opt size=120G fedora /bin/bash
|
||||
|
||||
This (size) will allow to set the container rootfs size to 120G at creation time.
|
||||
This option is only available for the `devicemapper`, `btrfs`, `overlay2` and `zfs` graph drivers.
|
||||
For the `devicemapper`, `btrfs` and `zfs` storage drivers, user cannot pass a size less than the Default BaseFS Size.
|
||||
For the `overlay2` storage driver, the size option is only available if the backing fs is `xfs` and mounted with the `pquota` mount option.
|
||||
Under these conditions, user can pass any size less then the backing fs size.
|
||||
|
||||
**--sysctl**=SYSCTL
|
||||
Configure namespaced kernel parameters at runtime
|
||||
|
||||
IPC Namespace - current sysctls allowed:
|
||||
|
||||
kernel.msgmax, kernel.msgmnb, kernel.msgmni, kernel.sem, kernel.shmall, kernel.shmmax, kernel.shmmni, kernel.shm_rmid_forced
|
||||
Sysctls beginning with fs.mqueue.*
|
||||
|
||||
Note: if you use the --ipc=host option these sysctls will not be allowed.
|
||||
|
||||
Network Namespace - current sysctls allowed:
|
||||
Sysctls beginning with net.*
|
||||
|
||||
Note: if you use the --network=host option these sysctls will not be allowed.
|
||||
|
||||
**--tmpfs**=[] Create a tmpfs mount
|
||||
|
||||
Mount a temporary filesystem (`tmpfs`) mount into a container, for example:
|
||||
|
||||
$ kpod run -d --tmpfs /tmp:rw,size=787448k,mode=1777 my_image
|
||||
|
||||
This command mounts a `tmpfs` at `/tmp` within the container. The supported mount
|
||||
options are the same as the Linux default `mount` flags. If you do not specify
|
||||
any options, the systems uses the following options:
|
||||
`rw,noexec,nosuid,nodev,size=65536k`.
|
||||
|
||||
**-t**, **--tty**=*true*|*false*
|
||||
Allocate a pseudo-TTY. The default is *false*.
|
||||
|
||||
When set to true kpod will allocate a pseudo-tty and attach to the standard
|
||||
input of the container. This can be used, for example, to run a throwaway
|
||||
interactive shell. The default is false.
|
||||
|
||||
Note: The **-t** option is incompatible with a redirection of the kpod client
|
||||
standard input.
|
||||
|
||||
**--ulimit**=[]
|
||||
Ulimit options
|
||||
|
||||
**-u**, **--user**=""
|
||||
Sets the username or UID used and optionally the groupname or GID for the specified command.
|
||||
|
||||
The followings examples are all valid:
|
||||
--user [user | user:group | uid | uid:gid | user:gid | uid:group ]
|
||||
|
||||
Without this argument the command will be run as root in the container.
|
||||
|
||||
**--userns**=""
|
||||
Set the usernamespace mode for the container when `userns-remap` option is enabled.
|
||||
**host**: use the host usernamespace and enable all privileged options (e.g., `pid=host` or `--privileged`).
|
||||
|
||||
**--uts**=*host*
|
||||
Set the UTS mode for the container
|
||||
**host**: use the host's UTS namespace inside the container.
|
||||
Note: the host mode gives the container access to changing the host's hostname and is therefore considered insecure.
|
||||
|
||||
**-v**|**--volume**[=*[[HOST-DIR:]CONTAINER-DIR[:OPTIONS]]*]
|
||||
Create a bind mount. If you specify, ` -v /HOST-DIR:/CONTAINER-DIR`, kpod
|
||||
bind mounts `/HOST-DIR` in the host to `/CONTAINER-DIR` in the kpod
|
||||
container. If 'HOST-DIR' is omitted, kpod automatically creates the new
|
||||
volume on the host. The `OPTIONS` are a comma delimited list and can be:
|
||||
|
||||
* [rw|ro]
|
||||
* [z|Z]
|
||||
* [`[r]shared`|`[r]slave`|`[r]private`]
|
||||
|
||||
The `CONTAINER-DIR` must be an absolute path such as `/src/docs`. The `HOST-DIR`
|
||||
can be an absolute path or a `name` value. A `name` value must start with an
|
||||
alphanumeric character, followed by `a-z0-9`, `_` (underscore), `.` (period) or
|
||||
`-` (hyphen). An absolute path starts with a `/` (forward slash).
|
||||
|
||||
If you supply a `HOST-DIR` that is an absolute path, kpod bind-mounts to the
|
||||
path you specify. If you supply a `name`, kpod creates a named volume by that
|
||||
`name`. For example, you can specify either `/foo` or `foo` for a `HOST-DIR`
|
||||
value. If you supply the `/foo` value, kpod creates a bind-mount. If you
|
||||
supply the `foo` specification, kpod creates a named volume.
|
||||
|
||||
You can specify multiple **-v** options to mount one or more mounts to a
|
||||
container. To use these same mounts in other containers, specify the
|
||||
**--volumes-from** option also.
|
||||
|
||||
You can add `:ro` or `:rw` suffix to a volume to mount it read-only or
|
||||
read-write mode, respectively. By default, the volumes are mounted read-write.
|
||||
See examples.
|
||||
|
||||
Labeling systems like SELinux require that proper labels are placed on volume
|
||||
content mounted into a container. Without a label, the security system might
|
||||
prevent the processes running inside the container from using the content. By
|
||||
default, kpod does not change the labels set by the OS.
|
||||
|
||||
To change a label in the container context, you can add either of two suffixes
|
||||
`:z` or `:Z` to the volume mount. These suffixes tell kpod to relabel file
|
||||
objects on the shared volumes. The `z` option tells kpod that two containers
|
||||
share the volume content. As a result, kpod labels the content with a shared
|
||||
content label. Shared volume labels allow all containers to read/write content.
|
||||
The `Z` option tells kpod to label the content with a private unshared label.
|
||||
Only the current container can use a private volume.
|
||||
|
||||
By default bind mounted volumes are `private`. That means any mounts done
|
||||
inside container will not be visible on host and vice-a-versa. One can change
|
||||
this behavior by specifying a volume mount propagation property. Making a
|
||||
volume `shared` mounts done under that volume inside container will be
|
||||
visible on host and vice-a-versa. Making a volume `slave` enables only one
|
||||
way mount propagation and that is mounts done on host under that volume
|
||||
will be visible inside container but not the other way around.
|
||||
|
||||
To control mount propagation property of volume one can use `:[r]shared`,
|
||||
`:[r]slave` or `:[r]private` propagation flag. Propagation property can
|
||||
be specified only for bind mounted volumes and not for internal volumes or
|
||||
named volumes. For mount propagation to work source mount point (mount point
|
||||
where source dir is mounted on) has to have right propagation properties. For
|
||||
shared volumes, source mount point has to be shared. And for slave volumes,
|
||||
source mount has to be either shared or slave.
|
||||
|
||||
Use `df <source-dir>` to figure out the source mount and then use
|
||||
`findmnt -o TARGET,PROPAGATION <source-mount-dir>` to figure out propagation
|
||||
properties of source mount. If `findmnt` utility is not available, then one
|
||||
can look at mount entry for source mount point in `/proc/self/mountinfo`. Look
|
||||
at `optional fields` and see if any propagaion properties are specified.
|
||||
`shared:X` means mount is `shared`, `master:X` means mount is `slave` and if
|
||||
nothing is there that means mount is `private`.
|
||||
|
||||
To change propagation properties of a mount point use `mount` command. For
|
||||
example, if one wants to bind mount source directory `/foo` one can do
|
||||
`mount --bind /foo /foo` and `mount --make-private --make-shared /foo`. This
|
||||
will convert /foo into a `shared` mount point. Alternatively one can directly
|
||||
change propagation properties of source mount. Say `/` is source mount for
|
||||
`/foo`, then use `mount --make-shared /` to convert `/` into a `shared` mount.
|
||||
|
||||
To disable automatic copying of data from the container path to the volume, use
|
||||
the `nocopy` flag. The `nocopy` flag can be set on bind mounts and named volumes.
|
||||
|
||||
**--volumes-from**=[]
|
||||
Mount volumes from the specified container(s)
|
||||
|
||||
Mounts already mounted volumes from a source container onto another
|
||||
container. You must supply the source's container-id. To share
|
||||
a volume, use the **--volumes-from** option when running
|
||||
the target container. You can share volumes even if the source container
|
||||
is not running.
|
||||
|
||||
By default, kpod mounts the volumes in the same mode (read-write or
|
||||
read-only) as it is mounted in the source container. Optionally, you
|
||||
can change this by suffixing the container-id with either the `:ro` or
|
||||
`:rw ` keyword.
|
||||
|
||||
If the location of the volume from the source container overlaps with
|
||||
data residing on a target container, then the volume hides
|
||||
that data on the target.
|
||||
|
||||
**-w**, **--workdir**=""
|
||||
Working directory inside the container
|
||||
|
||||
The default working directory for running binaries within a container is the root directory (/).
|
||||
The image developer can set a different default with the WORKDIR instruction. The operator
|
||||
can override the working directory by using the **-w** option.

## NAME
|

|
||||
[**--input**|**-i**]
|
||||
[**--quiet**|**-q**]
|
||||

|
||||
|
||||
## DESCRIPTION
|
||||
**kpod load** copies an image from either **docker-archive** or **oci-archive** stored
|
||||
on the local machine. **kpod load** reads from stdin by default or a file if the **input** flag is set.

# kpod load --quiet -i fedora.tar
|
||||
```

|

## NAME
|
||||
kpod-pull - Pull an image from a registry
|
||||
|
||||
## SYNOPSIS
|
||||
**kpod pull**
|
||||
**NAME[:TAG|@DIGEST]**
|
||||
[**--help**|**-h**]
|
||||
|
||||
## DESCRIPTION
|
||||
Copies an image from a registry onto the local machine. **kpod pull** pulls an
|
||||
image from Docker Hub if a registry is not specified in the command line argument.
|
||||
If an image tag is not specified, **kpod pull** defaults to the image with the
|
||||
**latest** tag (if it exists) and pulls it. **kpod pull** can also pull an image
|
||||
using its digest **kpod pull [image]@[digest]**. **kpod pull** can be used to pull
|
||||
images from archives and local storage using different transports.
|
||||
|
||||
## imageID
|
||||
Image stored in local container/storage
|
||||
|
||||
## SOURCE
|
||||
|
||||
The SOURCE is a location to get container images
|
||||
The Image "SOURCE" uses a "transport":"details" format.
|
||||
|
||||
Multiple transports are supported:
|
||||
|
||||
**dir:**_path_
|
||||
An existing local directory _path_ storing the manifest, layer tarballs and signatures as individual files. This is a non-standardized format, primarily useful for debugging or noninvasive container inspection.
|
||||
|
||||
**docker://**_docker-reference_
|
||||
An image in a registry implementing the "Docker Registry HTTP API V2". By default, uses the authorization state in `$XDG_RUNTIME_DIR/containers/auth.json`, which is set e.g. using `(kpod login)`.
|
||||
|
||||
**docker-archive:**_path_[**:**_docker-reference_]
|
||||
An image is stored in the `docker save` formatted file. _docker-reference_ is only used when creating such a file, and it must not contain a digest.
|
||||
|
||||
**docker-daemon:**_docker-reference_
|
||||
An image _docker-reference_ stored in the docker daemon internal storage. _docker-reference_ must contain either a tag or a digest. Alternatively, when reading images, the format can also be docker-daemon:algo:digest (an image ID).
|
||||
|
||||
**oci-archive:**_path_**:**_tag_
|
||||
An image _tag_ in a directory compliant with "Open Container Image Layout Specification" at _path_.
|
||||
|
||||
**ostree:**_image_[**@**_/absolute/repo/path_]
|
||||
An image in local OSTree repository. _/absolute/repo/path_ defaults to _/ostree/repo_.
|
||||
|
||||

||||
|
||||
**kpod pull [GLOBAL OPTIONS]**
|
||||
|
||||
**kpod pull NAME[:TAG|@DIGEST]**
|
||||
|
||||
## OPTIONS
|
||||
|
||||
**--authfile**
|
||||
|
||||
Path of the authentication file. Default is ${XDG_RUNTIME_DIR}/containers/auth.json
|
||||
|
||||
**--cert-dir**
|
||||
|
||||
Pathname of a directory containing TLS certificates and keys
|
||||
|
||||
**--creds**
|
||||
|
||||
Credentials (USERNAME:PASSWORD) to use for authenticating to a registry
|
||||
|
||||
**--quiet, -q**
|
||||
|
||||
Suppress output information when pulling images
|
||||
|
||||
**--signature-policy="PATHNAME"**
|
||||
|
||||
Pathname of a signature policy file to use. It is not recommended that this
|
||||
option be used, as the default behavior of using the system-wide default policy
|
||||
(frequently */etc/containers/policy.json*) is most often preferred
|
||||
|
||||
**--tls-verify**
|
||||
|
||||
Require HTTPS and verify certificates when contacting registries (default: true)
|
||||
|
||||

% kpod(1) kpod-run - Run a command in a container
|
||||
% Dan Walsh
|
||||
kpod-run - Run a command in a new container
|
||||
|
||||
# SYNOPSIS
|
||||
**kpod run** [*options* [...]] IMAGE [COMMAND] [ARG...]
|
||||
|
||||
# DESCRIPTION
|
||||
|
||||
Run a process in a new container. **kpod run** starts a process with its own
|
||||
file system, its own networking, and its own isolated process tree. The IMAGE
|
||||
which starts the process may define defaults related to the process that will be
|
||||
run in the container, the networking to expose, and more, but **kpod run**
|
||||
gives final control to the operator or administrator who starts the container
|
||||
from the image. For that reason **kpod run** has more options than any other
|
||||
kpod command.
|
||||
|
||||
If the IMAGE is not already loaded then **kpod run** will pull the IMAGE, and
|
||||
all image dependencies, from the repository in the same way running **kpod
|
||||
pull** IMAGE, before it starts the container from that image.
|
||||
|
||||
# OPTIONS
|
||||
**--add-host**=[]
|
||||
Add a custom host-to-IP mapping (host:ip)
|
||||
|
||||
Add a line to /etc/hosts. The format is hostname:ip. The **--add-host**
|
||||
option can be set multiple times.
|
||||
|
||||
**-a**, **--attach**=[]
|
||||
Attach to STDIN, STDOUT or STDERR.
|
||||
|
||||
In foreground mode (the default when **-d**
|
||||
is not specified), **kpod run** can start the process in the container
|
||||
and attach the console to the process's standard input, output, and standard
|
||||
error. It can even pretend to be a TTY (this is what most commandline
|
||||
executables expect) and pass along signals. The **-a** option can be set for
|
||||
each of stdin, stdout, and stderr.
|
||||
|
||||
**--blkio-weight**=*0*
|
||||
Block IO weight (relative weight) accepts a weight value between 10 and 1000.
|
||||
|
||||
**--blkio-weight-device**=[]
|
||||
Block IO weight (relative device weight, format: `DEVICE_NAME:WEIGHT`).
|
||||
|
||||
**--cap-add**=[]
|
||||
Add Linux capabilities
|
||||
|
||||
**--cap-drop**=[]
|
||||
Drop Linux capabilities
|
||||
|
||||
**--cgroup-parent**=""
|
||||
Path to cgroups under which the cgroup for the container will be created. If the path is not absolute, the path is considered to be relative to the cgroups path of the init process. Cgroups will be created if they do not already exist.
|
||||
|
||||
**--cidfile**=""
|
||||
Write the container ID to the file
|
||||
|
||||
**--cpu-count**=*0*
|
||||
Limit the number of CPUs available for execution by the container.
|
||||
|
||||
On Windows Server containers, this is approximated as a percentage of total CPU usage.
|
||||
|
||||
On Windows Server containers, the processor resource controls are mutually exclusive, the order of precedence is CPUCount first, then CPUShares, and CPUPercent last.
|
||||
|
||||
**--cpu-period**=*0*
|
||||
Limit the CPU CFS (Completely Fair Scheduler) period
|
||||
|
||||
Limit the container's CPU usage. This flag tell the kernel to restrict the container's CPU usage to the period you specify.
|
||||
|
||||
**--cpu-quota**=*0*
|
||||
Limit the CPU CFS (Completely Fair Scheduler) quota
|
||||
|
||||
Limit the container's CPU usage. By default, containers run with the full
|
||||
CPU resource. This flag tell the kernel to restrict the container's CPU usage
|
||||
to the quota you specify.
|
||||
|
||||
**--cpu-rt-period**=0
|
||||
Limit the CPU real-time period in microseconds
|
||||
|
||||
Limit the container's Real Time CPU usage. This flag tell the kernel to restrict the container's Real Time CPU usage to the period you specify.
|
||||
|
||||
**--cpu-rt-runtime**=0
|
||||
Limit the CPU real-time runtime in microseconds
|
||||
|
||||
Limit the containers Real Time CPU usage. This flag tells the kernel to limit the amount of time in a given CPU period Real Time tasks may consume. Ex:
|
||||
Period of 1,000,000us and Runtime of 950,000us means that this container could consume 95% of available CPU and leave the remaining 5% to normal priority tasks.
|
||||
|
||||
The sum of all runtimes across containers cannot exceed the amount allotted to the parent cgroup.
|
||||
|
||||
**--cpu-shares**=*0*
|
||||
CPU shares (relative weight)
|
||||
|
||||
By default, all containers get the same proportion of CPU cycles. This proportion
|
||||
can be modified by changing the container's CPU share weighting relative
|
||||
to the weighting of all other running containers.
|
||||
|
||||
To modify the proportion from the default of 1024, use the **--cpu-shares**
|
||||
flag to set the weighting to 2 or higher.
|
||||
|
||||
The proportion will only apply when CPU-intensive processes are running.
|
||||
When tasks in one container are idle, other containers can use the
|
||||
left-over CPU time. The actual amount of CPU time will vary depending on
|
||||
the number of containers running on the system.
|
||||
|
||||
For example, consider three containers, one has a cpu-share of 1024 and
|
||||
two others have a cpu-share setting of 512. When processes in all three
|
||||
containers attempt to use 100% of CPU, the first container would receive
|
||||
50% of the total CPU time. If you add a fourth container with a cpu-share
|
||||
of 1024, the first container only gets 33% of the CPU. The remaining containers
|
||||
receive 16.5%, 16.5% and 33% of the CPU.
|
||||
|
||||
On a multi-core system, the shares of CPU time are distributed over all CPU
|
||||
cores. Even if a container is limited to less than 100% of CPU time, it can
|
||||
use 100% of each individual CPU core.
|
||||
|
||||
For example, consider a system with more than three cores. If you start one
|
||||
container **{C0}** with **-c=512** running one process, and another container
|
||||
**{C1}** with **-c=1024** running two processes, this can result in the following
|
||||
division of CPU shares:
|
||||
|
||||
PID container CPU CPU share
|
||||
100 {C0} 0 100% of CPU0
|
||||
101 {C1} 1 100% of CPU1
|
||||
102 {C1} 2 100% of CPU2
|
||||
|
||||
**--cpus**=0.0
|
||||
Number of CPUs. The default is *0.0* which means no limit.
|
||||
|
||||
**--cpuset-cpus**=""
|
||||
CPUs in which to allow execution (0-3, 0,1)
|
||||
|
||||
**--cpuset-mems**=""
|
||||
Memory nodes (MEMs) in which to allow execution (0-3, 0,1). Only effective on NUMA systems.
|
||||
|
||||
If you have four memory nodes on your system (0-3), use `--cpuset-mems=0,1`
|
||||
then processes in your container will only use memory from the first
|
||||
two memory nodes.
|
||||
|
||||
**-d**, **--detach**=*true*|*false*
|
||||
Detached mode: run the container in the background and print the new container ID. The default is *false*.
|
||||
|
||||
At any time you can run **kpod ps** in
|
||||
the other shell to view a list of the running containers. You can reattach to a
|
||||
detached container with **kpod attach**. If you choose to run a container in
|
||||
the detached mode, then you cannot use the **-rm** option.
|
||||
|
||||
When attached in the tty mode, you can detach from the container (and leave it
|
||||
running) using a configurable key sequence. The default sequence is `CTRL-p CTRL-q`.
|
||||
You configure the key sequence using the **--detach-keys** option or a configuration file.
|
||||
See **config-json(5)** for documentation on using a configuration file.
|
||||
|
||||
**--detach-keys**=""
|
||||
Override the key sequence for detaching a container. Format is a single character `[a-Z]` or `ctrl-<value>` where `<value>` is one of: `a-z`, `@`, `^`, `[`, `,` or `_`.
|
||||
|
||||
**--device**=[]
|
||||
Add a host device to the container (e.g. --device=/dev/sdc:/dev/xvdc:rwm)
|
||||
|
||||
**--device-read-bps**=[]
|
||||
Limit read rate (bytes per second) from a device (e.g. --device-read-bps=/dev/sda:1mb)
|
||||
|
||||
**--device-read-iops**=[]
|
||||
Limit read rate (IO per second) from a device (e.g. --device-read-iops=/dev/sda:1000)
|
||||
|
||||
**--device-write-bps**=[]
|
||||
Limit write rate (bytes per second) to a device (e.g. --device-write-bps=/dev/sda:1mb)
|
||||
|
||||
**--device-write-iops**=[]
|
||||
Limit write rate (IO per second) to a device (e.g. --device-write-iops=/dev/sda:1000)
|
||||
|
||||
**--dns**=[]
|
||||
Set custom DNS servers
|
||||
|
||||
This option can be used to override the DNS
|
||||
configuration passed to the container. Typically this is necessary when the
|
||||
host DNS configuration is invalid for the container (e.g., 127.0.0.1). When this
|
||||
is the case the **--dns** flags is necessary for every run.
|
||||
|
||||
**--dns-option**=[]
|
||||
Set custom DNS options
|
||||
|
||||
**--dns-search**=[]
|
||||
Set custom DNS search domains (Use --dns-search=. if you don't wish to set the search domain)
|
||||
|
||||
**--entrypoint**=""
|
||||
Overwrite the default ENTRYPOINT of the image
|
||||
|
||||
This option allows you to overwrite the default entrypoint of the image.
|
||||
The ENTRYPOINT of an image is similar to a COMMAND
|
||||
because it specifies what executable to run when the container starts, but it is
|
||||
(purposely) more difficult to override. The ENTRYPOINT gives a container its
|
||||
default nature or behavior, so that when you set an ENTRYPOINT you can run the
|
||||
container as if it were that binary, complete with default options, and you can
|
||||
pass in more options via the COMMAND. But, sometimes an operator may want to run
|
||||
something else inside the container, so you can override the default ENTRYPOINT
|
||||
at runtime by using a **--entrypoint** and a string to specify the new
|
||||
ENTRYPOINT.
|
||||
|
||||
**-e**, **--env**=[]
|
||||
Set environment variables
|
||||
|
||||
This option allows you to specify arbitrary
|
||||
environment variables that are available for the process that will be launched
|
||||
inside of the container.
|
||||
|
||||
**--env-file**=[]
|
||||
Read in a line delimited file of environment variables
|
||||
|
||||
**--expose**=[]
|
||||
Expose a port, or a range of ports (e.g. --expose=3300-3310) to set up port redirection
|
||||
on the host system.
|
||||
|
||||
**--group-add**=[]
|
||||
Add additional groups to run as
|
||||
|
||||
**--hostname**=""
|
||||
Container host name
|
||||
|
||||
Sets the container host name that is available inside the container.
|
||||
|
||||
**--help**
|
||||
Print usage statement
|
||||
|
||||
**-i**, **--interactive**=*true*|*false*
|
||||
Keep STDIN open even if not attached. The default is *false*.
|
||||
|
||||
When set to true, keep stdin open even if not attached. The default is false.
|
||||
|
||||
**--ip**=""
|
||||
Sets the container's interface IPv4 address (e.g. 172.23.0.9)
|
||||
|
||||
It can only be used in conjunction with **--network** for user-defined networks
|
||||
|
||||
**--ip6**=""
|
||||
Sets the container's interface IPv6 address (e.g. 2001:db8::1b99)
|
||||
|
||||
It can only be used in conjunction with **--network** for user-defined networks
|
||||
|
||||
**--ipc**=""
|
||||
Default is to create a private IPC namespace (POSIX SysV IPC) for the container
|
||||
'container:<name|id>': reuses another container shared memory, semaphores and message queues
|
||||
'host': use the host shared memory,semaphores and message queues inside the container. Note: the host mode gives the container full access to local shared memory and is therefore considered insecure.
|
||||
|
||||
**--kernel-memory**=""
|
||||
Kernel memory limit (format: `<number>[<unit>]`, where unit = b, k, m or g)
|
||||
|
||||
Constrains the kernel memory available to a container. If a limit of 0
|
||||
is specified (not using `--kernel-memory`), the container's kernel memory
|
||||
is not limited. If you specify a limit, it may be rounded up to a multiple
|
||||
of the operating system's page size and the value can be very large,
|
||||
millions of trillions.
|
||||
|
||||
**-l**, **--label**=[]
|
||||
Add metadata to a container (e.g., --label com.example.key=value)
|
||||
|
||||
**--label-file**=[]
|
||||
Read in a line delimited file of labels
|
||||
|
||||
**--link-local-ip**=[]
|
||||
Add one or more link-local IPv4/IPv6 addresses to the container's interface
|
||||
|
||||
**--log-driver**="*json-file*|*syslog*|*journald*|*gelf*|*fluentd*|*awslogs*|*splunk*|*etwlogs*|*gcplogs*|*none*"
|
||||
Logging driver for the container. Default is defined by daemon `--log-driver` flag.
|
||||
**Warning**: the `kpod logs` command works only for the `json-file` and
|
||||
`journald` logging drivers.
|
||||
|
||||
**--log-opt**=[]
|
||||
Logging driver specific options.
|
||||
|
||||
**--mac-address**=""
|
||||
Container MAC address (e.g. 92:d0:c6:0a:29:33)
|
||||
|
||||
Remember that the MAC address in an Ethernet network must be unique.
|
||||
The IPv6 link-local address will be based on the device's MAC address
|
||||
according to RFC4862.
|
||||
|
||||
**-m**, **--memory**=""
|
||||
Memory limit (format: <number>[<unit>], where unit = b, k, m or g)
|
||||
|
||||
Allows you to constrain the memory available to a container. If the host
|
||||
supports swap memory, then the **-m** memory setting can be larger than physical
|
||||
RAM. If a limit of 0 is specified (not using **-m**), the container's memory is
|
||||
not limited. The actual limit may be rounded up to a multiple of the operating
|
||||
system's page size (the value would be very large, that's millions of trillions).
|
||||
|
||||
**--memory-reservation**=""
|
||||
Memory soft limit (format: <number>[<unit>], where unit = b, k, m or g)
|
||||
|
||||
After setting memory reservation, when the system detects memory contention
|
||||
or low memory, containers are forced to restrict their consumption to their
|
||||
reservation. So you should always set the value below **--memory**, otherwise the
|
||||
hard limit will take precedence. By default, memory reservation will be the same
|
||||
as memory limit.
|
||||
|
||||
**--memory-swap**="LIMIT"
|
||||
A limit value equal to memory plus swap. Must be used with the **-m**
|
||||
(**--memory**) flag. The swap `LIMIT` should always be larger than **-m**
|
||||
(**--memory**) value. By default, the swap `LIMIT` will be set to double
|
||||
the value of --memory.
|
||||
|
||||
The format of `LIMIT` is `<number>[<unit>]`. Unit can be `b` (bytes),
|
||||
`k` (kilobytes), `m` (megabytes), or `g` (gigabytes). If you don't specify a
|
||||
unit, `b` is used. Set LIMIT to `-1` to enable unlimited swap.
|
||||
|
||||
**--memory-swappiness**=""
|
||||
Tune a container's memory swappiness behavior. Accepts an integer between 0 and 100.
|
||||
|
||||
**--name**=""
|
||||
Assign a name to the container
|
||||
|
||||
The operator can identify a container in three ways:
|
||||
UUID long identifier (“f78375b1c487e03c9438c729345e54db9d20cfa2ac1fc3494b6eb60872e74778”)
|
||||
UUID short identifier (“f78375b1c487”)
|
||||
Name (“jonah”)
|
||||
|
||||
kpod generates a UUID for each container, and if a name is not assigned
|
||||
to the container with **--name** then the daemon will also generate a random
|
||||
string name. The name is useful when defining links (see **--link**) (or any
|
||||
other place you need to identify a container). This works for both background
|
||||
and foreground containers.
|
||||
|
||||
**--network**="*bridge*"
|
||||
Set the Network mode for the container
|
||||
'bridge': create a network stack on the default bridge
|
||||
'none': no networking
|
||||
'container:<name|id>': reuse another container's network stack
|
||||
'host': use the kpod host network stack. Note: the host mode gives the container full access to local system services such as D-bus and is therefore considered insecure.
|
||||
'<network-name>|<network-id>': connect to a user-defined network
|
||||
|
||||
**--network-alias**=[]
|
||||
Add network-scoped alias for the container
|
||||
|
||||
**--oom-kill-disable**=*true*|*false*
|
||||
Whether to disable OOM Killer for the container or not.
|
||||
|
||||
**--oom-score-adj**=""
|
||||
Tune the host's OOM preferences for containers (accepts -1000 to 1000)
|
||||
|
||||
**--pid**=""
|
||||
Set the PID mode for the container
|
||||
Default is to create a private PID namespace for the container
|
||||
'container:<name|id>': join another container's PID namespace
|
||||
'host': use the host's PID namespace for the container. Note: the host mode gives the container full access to local PID and is therefore considered insecure.
|
||||
|
||||
**--pids-limit**=""
|
||||
Tune the container's pids limit. Set `-1` to have unlimited pids for the container.
|
||||
|
||||
**--pod**=""
|
||||
Run container in an existing pod
|
||||
|
||||
**--privileged**=*true*|*false*
|
||||
Give extended privileges to this container. The default is *false*.
|
||||
|
||||
By default, kpod containers are
|
||||
“unprivileged” (=false) and cannot, for example, modify parts of the kernel.
|
||||
This is because by default a container is not allowed to access any devices.
|
||||
A “privileged” container is given access to all devices.
|
||||
|
||||
When the operator executes **kpod run --privileged**, kpod enables access
|
||||
to all devices on the host as well as set turn off most of the security messurs
|
||||
protecting the host from the container.
|
||||
|
||||
**-p**, **--publish**=[]
|
||||
Publish a container's port, or range of ports, to the host
|
||||
|
||||
Format: `ip:hostPort:containerPort | ip::containerPort | hostPort:containerPort | containerPort`
|
||||
Both hostPort and containerPort can be specified as a range of ports.
|
||||
When specifying ranges for both, the number of container ports in the range must match the number of host ports in the range.
|
||||
(e.g., `kpod run -p 1234-1236:1222-1224 --name thisWorks -t busybox`
|
||||
but not `kpod run -p 1230-1236:1230-1240 --name RangeContainerPortsBiggerThanRangeHostPorts -t busybox`)
|
||||
With ip: `kpod run -p 127.0.0.1:$HOSTPORT:$CONTAINERPORT --name CONTAINER -t someimage`
|
||||
Use `kpod port` to see the actual mapping: `kpod port CONTAINER $CONTAINERPORT`
|
||||
|
||||
**-P**, **--publish-all**=*true*|*false*
|
||||
Publish all exposed ports to random ports on the host interfaces. The default is *false*.
|
||||
|
||||
When set to true publish all exposed ports to the host interfaces. The
|
||||
default is false. If the operator uses -P (or -p) then kpod will make the
|
||||
exposed port accessible on the host and the ports will be available to any
|
||||
client that can reach the host. When using -P, kpod will bind any exposed
|
||||
port to a random port on the host within an *ephemeral port range* defined by
|
||||
`/proc/sys/net/ipv4/ip_local_port_range`. To find the mapping between the host
|
||||
ports and the exposed ports, use `kpod port`.
|
||||
|
||||
**--read-only**=*true*|*false*
|
||||
Mount the container's root filesystem as read only.
|
||||
|
||||
By default a container will have its root filesystem writable allowing processes
|
||||
to write files anywhere. By specifying the `--read-only` flag the container will have
|
||||
its root filesystem mounted as read only prohibiting any writes.
|
||||
|
||||
**--rm**=*true*|*false*
|
||||
Automatically remove the container when it exits. The default is *false*.
|
||||
`--rm` flag can work together with `-d`, and auto-removal will be done on daemon side. Note that it's
|
||||
incompatible with any restart policy other than `none`.
|
||||
|
||||
**--security-opt**=[]
|
||||
Security Options
|
||||
|
||||
"label=user:USER" : Set the label user for the container
|
||||
"label=role:ROLE" : Set the label role for the container
|
||||
"label=type:TYPE" : Set the label type for the container
|
||||
"label=level:LEVEL" : Set the label level for the container
|
||||
"label=disable" : Turn off label confinement for the container
|
||||
"no-new-privileges" : Disable container processes from gaining additional privileges
|
||||
|
||||
"seccomp=unconfined" : Turn off seccomp confinement for the container
|
||||
"seccomp=profile.json : White listed syscalls seccomp Json file to be used as a seccomp filter
|
||||
|
||||
"apparmor=unconfined" : Turn off apparmor confinement for the container
|
||||
"apparmor=your-profile" : Set the apparmor confinement profile for the container
|
||||
|
||||
**--shm-size**=""
|
||||
Size of `/dev/shm`. The format is `<number><unit>`. `number` must be greater than `0`.
|
||||
Unit is optional and can be `b` (bytes), `k` (kilobytes), `m`(megabytes), or `g` (gigabytes).
|
||||
If you omit the unit, the system uses bytes. If you omit the size entirely, the system uses `64m`.
|
||||
|
||||
**--sig-proxy**=*true*|*false*
|
||||
Proxy received signals to the process (non-TTY mode only). SIGCHLD, SIGSTOP, and SIGKILL are not proxied. The default is *true*.
|
||||
|
||||
**--stop-signal**=*SIGTERM*
|
||||
Signal to stop a container. Default is SIGTERM.
|
||||
|
||||
**--stop-timeout**=*10*
|
||||
Timeout (in seconds) to stop a container. Default is 10.
|
||||
|
||||
**--storage-opt**=[]
|
||||
Storage driver options per container
|
||||
|
||||
$ kpod run -it --storage-opt size=120G fedora /bin/bash
|
||||
|
||||
This (size) will allow to set the container rootfs size to 120G at creation time.
|
||||
This option is only available for the `devicemapper`, `btrfs`, `overlay2` and `zfs` graph drivers.
|
||||
For the `devicemapper`, `btrfs` and `zfs` storage drivers, user cannot pass a size less than the Default BaseFS Size.
|
||||
For the `overlay2` storage driver, the size option is only available if the backing fs is `xfs` and mounted with the `pquota` mount option.
|
||||
Under these conditions, user can pass any size less then the backing fs size.
|
||||
|
||||
**--sysctl**=SYSCTL
|
||||
Configure namespaced kernel parameters at runtime
|
||||
|
||||
IPC Namespace - current sysctls allowed:
|
||||
|
||||
kernel.msgmax, kernel.msgmnb, kernel.msgmni, kernel.sem, kernel.shmall, kernel.shmmax, kernel.shmmni, kernel.shm_rmid_forced
|
||||
Sysctls beginning with fs.mqueue.*
|
||||
|
||||
Note: if you use the `--ipc=host` option these sysctls will not be allowed.
|
||||
|
||||
Network Namespace - current sysctls allowed:
|
||||
Sysctls beginning with net.*
|
||||
|
||||
Note: if you use the `--network=host` option these sysctls will not be allowed.
|
||||
|
||||
**--tmpfs**=[] Create a tmpfs mount
|
||||
|
||||
Mount a temporary filesystem (`tmpfs`) mount into a container, for example:
|
||||
|
||||
$ kpod run -d --tmpfs /tmp:rw,size=787448k,mode=1777 my_image
|
||||
|
||||
This command mounts a `tmpfs` at `/tmp` within the container. The supported mount
|
||||
options are the same as the Linux default `mount` flags. If you do not specify
|
||||
any options, the systems uses the following options:
|
||||
`rw,noexec,nosuid,nodev,size=65536k`.
|
||||
|
||||
**-t**, **--tty**=*true*|*false*
|
||||
Allocate a pseudo-TTY. The default is *false*.
|
||||
|
||||
When set to true kpod will allocate a pseudo-tty and attach to the standard
|
||||
input of the container. This can be used, for example, to run a throwaway
|
||||
interactive shell. The default is false.
|
||||
|
||||
Note: The **-t** option is incompatible with a redirection of the kpod client
|
||||
standard input.
|
||||
|
||||
**--ulimit**=[]
|
||||
Ulimit options
|
||||
|
||||
**-u**, **--user**=""
|
||||
Sets the username or UID used and optionally the groupname or GID for the specified command.
|
||||
|
||||
The followings examples are all valid:
|
||||
--user [user | user:group | uid | uid:gid | user:gid | uid:group ]
|
||||
|
||||
Without this argument the command will be run as root in the container.
|
||||
|
||||
**--userns**=""
|
||||
Set the usernamespace mode for the container when `userns-remap` option is enabled.
|
||||
**host**: use the host usernamespace and enable all privileged options (e.g., `pid=host` or `--privileged`).
|
||||
|
||||
**--uts**=*host*
|
||||
Set the UTS mode for the container
|
||||
**host**: use the host's UTS namespace inside the container.
|
||||
Note: the host mode gives the container access to changing the host's hostname and is therefore considered insecure.
|
||||
|
||||
**-v**|**--volume**[=*[[HOST-DIR:]CONTAINER-DIR[:OPTIONS]]*]
|
||||
Create a bind mount. If you specify, ` -v /HOST-DIR:/CONTAINER-DIR`, kpod
|
||||
bind mounts `/HOST-DIR` in the host to `/CONTAINER-DIR` in the kpod
|
||||
container. If 'HOST-DIR' is omitted, kpod automatically creates the new
|
||||
volume on the host. The `OPTIONS` are a comma delimited list and can be:
|
||||
|
||||
* [rw|ro]
|
||||
* [z|Z]
|
||||
* [`[r]shared`|`[r]slave`|`[r]private`]
|
||||
* [nocopy]
|
||||
|
||||
The `CONTAINER-DIR` must be an absolute path such as `/src/docs`. The `HOST-DIR`
|
||||
can be an absolute path or a `name` value. A `name` value must start with an
|
||||
alphanumeric character, followed by `a-z0-9`, `_` (underscore), `.` (period) or
|
||||
`-` (hyphen). An absolute path starts with a `/` (forward slash).
|
||||
|
||||
If you supply a `HOST-DIR` that is an absolute path, kpod bind-mounts to the
|
||||
path you specify. If you supply a `name`, kpod creates a named volume by that
|
||||
`name`. For example, you can specify either `/foo` or `foo` for a `HOST-DIR`
|
||||
value. If you supply the `/foo` value, kpod creates a bind-mount. If you
|
||||
supply the `foo` specification, kpod creates a named volume.
|
||||
|
||||
You can specify multiple **-v** options to mount one or more mounts to a
|
||||
container. To use these same mounts in other containers, specify the
|
||||
**--volumes-from** option also.
|
||||
|
||||
You can add `:ro` or `:rw` suffix to a volume to mount it read-only or
|
||||
read-write mode, respectively. By default, the volumes are mounted read-write.
|
||||
See examples.
|
||||
|
||||
Labeling systems like SELinux require that proper labels are placed on volume
|
||||
content mounted into a container. Without a label, the security system might
|
||||
prevent the processes running inside the container from using the content. By
|
||||
default, kpod does not change the labels set by the OS.
|
||||
|
||||
To change a label in the container context, you can add either of two suffixes
|
||||
`:z` or `:Z` to the volume mount. These suffixes tell kpod to relabel file
|
||||
objects on the shared volumes. The `z` option tells kpod that two containers
|
||||
share the volume content. As a result, kpod labels the content with a shared
|
||||
content label. Shared volume labels allow all containers to read/write content.
|
||||
The `Z` option tells kpod to label the content with a private unshared label.
|
||||
Only the current container can use a private volume.
|
||||
|
||||
By default bind mounted volumes are `private`. That means any mounts done
|
||||
inside container will not be visible on host and vice-a-versa. One can change
|
||||
this behavior by specifying a volume mount propagation property. Making a
|
||||
volume `shared` mounts done under that volume inside container will be
|
||||
visible on host and vice-a-versa. Making a volume `slave` enables only one
|
||||
way mount propagation and that is mounts done on host under that volume
|
||||
will be visible inside container but not the other way around.
|
||||
|
||||
To control mount propagation property of volume one can use `:[r]shared`,
|
||||
`:[r]slave` or `:[r]private` propagation flag. Propagation property can
|
||||
be specified only for bind mounted volumes and not for internal volumes or
|
||||
named volumes. For mount propagation to work source mount point (mount point
|
||||
where source dir is mounted on) has to have right propagation properties. For
|
||||
shared volumes, source mount point has to be shared. And for slave volumes,
|
||||
source mount has to be either shared or slave.
|
||||
|
||||
Use `df <source-dir>` to figure out the source mount and then use
|
||||
`findmnt -o TARGET,PROPAGATION <source-mount-dir>` to figure out propagation
|
||||
properties of source mount. If `findmnt` utility is not available, then one
|
||||
can look at mount entry for source mount point in `/proc/self/mountinfo`. Look
|
||||
at `optional fields` and see if any propagaion properties are specified.
|
||||
`shared:X` means mount is `shared`, `master:X` means mount is `slave` and if
|
||||
nothing is there that means mount is `private`.
|
||||
|
||||
To change propagation properties of a mount point use `mount` command. For
|
||||
example, if one wants to bind mount source directory `/foo` one can do
|
||||
`mount --bind /foo /foo` and `mount --make-private --make-shared /foo`. This
|
||||
will convert /foo into a `shared` mount point. Alternatively one can directly
|
||||
change propagation properties of source mount. Say `/` is source mount for
|
||||
`/foo`, then use `mount --make-shared /` to convert `/` into a `shared` mount.
|
||||
|
||||
To disable automatic copying of data from the container path to the volume, use
|
||||
the `nocopy` flag. The `nocopy` flag can be set on bind mounts and named volumes.
|
||||
|
||||
**--volumes-from**=[]
|
||||
Mount volumes from the specified container(s)
|
||||
|
||||
Mounts already mounted volumes from a source container onto another
|
||||
container. You must supply the source's container-id. To share
|
||||
a volume, use the **--volumes-from** option when running
|
||||
the target container. You can share volumes even if the source container
|
||||
is not running.
|
||||
|
||||
By default, kpod mounts the volumes in the same mode (read-write or
|
||||
read-only) as it is mounted in the source container. Optionally, you
|
||||
can change this by suffixing the container-id with either the `:ro` or
|
||||
`:rw ` keyword.
|
||||
|
||||
If the location of the volume from the source container overlaps with
|
||||
data residing on a target container, then the volume hides
|
||||
that data on the target.
|
||||
|
||||
**-w**, **--workdir**=""
|
||||
Working directory inside the container
|
||||
|
||||
The default working directory for running binaries within a container is the root directory (/).
|
||||
The image developer can set a different default with the WORKDIR instruction. The operator
|
||||
can override the working directory by using the **-w** option.
|
||||
|
||||
# Exit Status
|
||||
|
||||
The exit code from `kpod run` gives information about why the container
|
||||
failed to run or why it exited. When `kpod run` exits with a non-zero code,
|
||||
the exit codes follow the `chroot` standard, see below:
|
||||
|
||||
**_125_** if the error is with kpod **_itself_**
|
||||
|
||||
$ kpod run --foo busybox; echo $?
|
||||
# flag provided but not defined: --foo
|
||||
See 'kpod run --help'.
|
||||
125
|
||||
|
||||
**_126_** if the **_contained command_** cannot be invoked
|
||||
|
||||
$ kpod run busybox /etc; echo $?
|
||||
# exec: "/etc": permission denied
|
||||
kpod: Error response from daemon: Contained command could not be invoked
|
||||
126
|
||||
|
||||
**_127_** if the **_contained command_** cannot be found
|
||||
|
||||
$ kpod run busybox foo; echo $?
|
||||
# exec: "foo": executable file not found in $PATH
|
||||
kpod: Error response from daemon: Contained command not found or does not exist
|
||||
127
|
||||
|
||||
**_Exit code_** of **_contained command_** otherwise
|
||||
|
||||
$ kpod run busybox /bin/sh -c 'exit 3'
|

# EXAMPLES
|
||||
|
||||
## Running container in read-only mode
|
||||
|
||||
During container image development, containers often need to write to the image
|
||||
content. Installing packages into /usr, for example. In production,
|
||||
applications seldom need to write to the image. Container applications write
|
||||
to volumes if they need to write to file systems at all. Applications can be
|
||||
made more secure by running them in read-only mode using the - -read-only switch.
|
||||
This protects the containers image from modification. Read only containers may
|
||||
still need to write temporary data. The best way to handle this is to mount
|
||||
tmpfs directories on /run and /tmp.
|
||||
|
||||
# kpod run --read-only --tmpfs /run --tmpfs /tmp -i -t fedora /bin/bash
|
||||
|
||||
## Exposing log messages from the container to the host's log
|
||||
|
||||
If you want messages that are logged in your container to show up in the host's
|
||||
syslog/journal then you should bind mount the /dev/log directory as follows.
|
||||
|
||||
# kpod run -v /dev/log:/dev/log -i -t fedora /bin/bash
|
||||
|
||||
From inside the container you can test this by sending a message to the log.
|
||||
|
||||
(bash)# logger "Hello from my container"
|
||||
|
||||
Then exit and check the journal.
|
||||
|
||||
# exit
|
||||
|
||||
# journalctl -b | grep Hello
|
||||
|
||||
This should list the message sent to logger.
|
||||
|
||||
## Attaching to one or more from STDIN, STDOUT, STDERR
|
||||
|
||||
If you do not specify -a then kpod will attach everything (stdin,stdout,stderr)
|
||||
. You can specify to which of the three standard streams (stdin, stdout, stderr)
|
||||
you'd like to connect instead, as in:
|
||||
|
||||
# kpod run -a stdin -a stdout -i -t fedora /bin/bash
|
||||
|
||||
## Sharing IPC between containers
|
||||
|
||||
Using shm_server.c available here: https://www.cs.cf.ac.uk/Dave/C/node27.html
|
||||
|
||||
Testing `--ipc=host` mode:
|
||||
|
||||
Host shows a shared memory segment with 7 pids attached, happens to be from httpd:
|
||||
|
||||
```
|
||||
$ sudo ipcs -m
|
||||
|
||||
------ Shared Memory Segments --------
|
||||
key shmid owner perms bytes nattch status
|
||||
0x01128e25 0 root 600 1000 7
|
||||
```
|
||||
|
||||
Now run a regular container, and it correctly does NOT see the shared memory segment from the host:
|
||||
|
||||
```
|
||||
$ kpod run -it shm ipcs -m
|
||||
|
||||
------ Shared Memory Segments --------
|
||||
key shmid owner perms bytes nattch status
|
||||
```
|
||||
|
||||
Run a container with the new `--ipc=host` option, and it now sees the shared memory segment from the host httpd:
|
||||
|
||||
```
|
||||
$ kpod run -it --ipc=host shm ipcs -m
|
||||
|
||||
------ Shared Memory Segments --------
|
||||
key shmid owner perms bytes nattch status
|
||||
0x01128e25 0 root 600 1000 7
|
||||
```
|
||||
Testing `--ipc=container:CONTAINERID` mode:
|
||||
|
||||
Start a container with a program to create a shared memory segment:
|
||||
```
|
||||
$ kpod run -it shm bash
|
||||
$ sudo shm/shm_server &
|
||||
$ sudo ipcs -m
|
||||
|
||||
------ Shared Memory Segments --------
|
||||
key shmid owner perms bytes nattch status
|
||||
0x0000162e 0 root 666 27 1
|
||||
```
|
||||
Create a 2nd container correctly shows no shared memory segment from 1st container:
|
||||
```
|
||||
$ kpod run shm ipcs -m
|
||||
|
||||
------ Shared Memory Segments --------
|
||||
key shmid owner perms bytes nattch status
|
||||
```
|
||||
|
||||
Create a 3rd container using the new --ipc=container:CONTAINERID option, now it shows the shared memory segment from the first:
|
||||
|
||||
```
|
||||
$ kpod run -it --ipc=container:ed735b2264ac shm ipcs -m
|
||||
$ sudo ipcs -m
|
||||
|
||||
------ Shared Memory Segments --------
|
||||
key shmid owner perms bytes nattch status
|
||||
0x0000162e 0 root 666 27 1
|
||||
```
|
||||
|
||||
## Mapping Ports for External Usage
|
||||
|
||||
The exposed port of an application can be mapped to a host port using the **-p**
|
||||
flag. For example, an httpd port 80 can be mapped to the host port 8080 using the
|
||||
following:
|
||||
|
||||
# kpod run -p 8080:80 -d -i -t fedora/httpd
|
||||
|
||||
## Creating and Mounting a Data Volume Container
|
||||
|
||||
Many applications require the sharing of persistent data across several
|
||||
containers. kpod allows you to create a Data Volume Container that other
|
||||
containers can mount from. For example, create a named container that contains
|
||||
directories /var/volume1 and /tmp/volume2. The image will need to contain these
|
||||
directories so a couple of RUN mkdir instructions might be required for you
|
||||
fedora-data image:
|
||||
|
||||
# kpod run --name=data -v /var/volume1 -v /tmp/volume2 -i -t fedora-data true
|
||||
# kpod run --volumes-from=data --name=fedora-container1 -i -t fedora bash
|
||||
|
||||
Multiple --volumes-from parameters will bring together multiple data volumes from
|
||||
multiple containers. And it's possible to mount the volumes that came from the
|
||||
DATA container in yet another container via the fedora-container1 intermediary
|
||||
container, allowing to abstract the actual data source from users of that data:
|
||||
|
||||
# kpod run --volumes-from=fedora-container1 --name=fedora-container2 -i -t fedora bash
|
||||
|
||||
## Mounting External Volumes
|
||||
|
||||
To mount a host directory as a container volume, specify the absolute path to
|
||||
the directory and the absolute path for the container directory separated by a
|
||||
colon:
|
||||
|
||||
# kpod run -v /var/db:/data1 -i -t fedora bash
|
||||
|
||||
When using SELinux, be aware that the host has no knowledge of container SELinux
|
||||
policy. Therefore, in the above example, if SELinux policy is enforced, the
|
||||
`/var/db` directory is not writable to the container. A "Permission Denied"
|
||||
message will occur and an avc: message in the host's syslog.
|
||||
|
||||
|
||||
To work around this, at time of writing this man page, the following command
|
||||
needs to be run in order for the proper SELinux policy type label to be attached
|
||||
to the host directory:
|
||||
|
||||
# chcon -Rt svirt_sandbox_file_t /var/db
|
||||
|
||||
|
||||
Now, writing to the /data1 volume in the container will be allowed and the
|
||||
changes will also be reflected on the host in /var/db.
|
||||
|
||||
## Using alternative security labeling
|
||||
|
||||
You can override the default labeling scheme for each container by specifying
|
||||
the `--security-opt` flag. For example, you can specify the MCS/MLS level, a
|
||||
requirement for MLS systems. Specifying the level in the following command
|
||||
allows you to share the same content between containers.
|
||||
|
||||
# kpod run --security-opt label=level:s0:c100,c200 -i -t fedora bash
|
||||
|
||||
An MLS example might be:
|
||||
|
||||
# kpod run --security-opt label=level:TopSecret -i -t rhel7 bash
|
||||
|
||||
To disable the security labeling for this container versus running with the
|
||||
`--permissive` flag, use the following command:
|
||||
|
||||
# kpod run --security-opt label=disable -i -t fedora bash
|
||||
|
||||
If you want a tighter security policy on the processes within a container,
|
||||
you can specify an alternate type for the container. You could run a container
|
||||
that is only allowed to listen on Apache ports by executing the following
|
||||
command:
|
||||
|
||||
# kpod run --security-opt label=type:svirt_apache_t -i -t centos bash
|
||||
|
||||
Note:
|
||||
|
||||
You would have to write policy defining a `svirt_apache_t` type.
|
||||
|
||||
## Setting device weight
|
||||
|
||||
If you want to set `/dev/sda` device weight to `200`, you can specify the device
|
||||
weight by `--blkio-weight-device` flag. Use the following command:
|
||||
|
||||
# kpod run -it --blkio-weight-device "/dev/sda:200" ubuntu
|
||||
|
||||
```
|
||||
$ kpod run -d busybox top
|
||||
```
|
||||
|
||||
## Setting Namespaced Kernel Parameters (Sysctls)
|
||||
|
||||
The `--sysctl` sets namespaced kernel parameters (sysctls) in the
|
||||
container. For example, to turn on IP forwarding in the containers
|
||||
network namespace, run this command:
|
||||
|
||||
$ kpod run --sysctl net.ipv4.ip_forward=1 someimage
|
||||
|
||||
Note:
|
||||
|
||||
Not all sysctls are namespaced. kpod does not support changing sysctls
|
||||
inside of a container that also modify the host system. As the kernel
|
||||
evolves we expect to see more sysctls become namespaced.
|
||||
|
||||
See the definition of the `--sysctl` option above for the current list of
|
||||
supported sysctls.

## SYNOPSIS
|
||||
**kpod** [*options*] COMMAND
|
||||
|
||||
# DESCRIPTION
|
||||
kpod is a simple client only tool to help with debugging issues when daemons
|
||||
such as CRI runtime and the kubelet are not responding or failing. A shared API
|
||||
layer could be created to share code between the daemon and kpod. kpod does not
|
||||
require any daemon running. kpod utilizes the same underlying components that
|
||||
crio uses i.e. containers/image, container/storage, oci-runtime-tool/generate,
|
||||
runc or any other OCI compatible runtime. kpod shares state with crio and so
|
||||
has the capability to debug pods/images created by crio.
|
||||
