storage: fix image retrieval by id 
kubelet sends a request to create a container with an image ID (as
opposed as an image name). That ID comes from the ImageStatus response.
This patch fixes that by setting the image ID as well as the image name
and fix the login to lookup for image ID as well.

Found while running `make test-e2e-node`.

aeea656581 Limit implicit image pulling to the pause image 
The CRI doesn't expect us to implicitly pull an image if it isn't
already present before we're asked to use it to create a container, and
the tests no longer depend on us doing so, either.

Limit the logic which attempts to pull an image, if it isn't present, to
only pulling the configured "pause" image, since our use of that image
for running pod sandboxes is an implementation detail that our clients
can't be expected to know or care about.  Include the name of the image
that we didn't pull in the error we return when we don't pull one.

c0333b102b Integrate containers/storage 
Use containers/storage to store images, pod sandboxes, and containers.
A pod sandbox's infrastructure container has the same ID as the pod to
which it belongs, and all containers also keep track of their pod's ID.

The container configuration that we build using the data in a
CreateContainerRequest is stored in the container's ContainerDirectory
and ContainerRunDirectory.

We catch SIGTERM and SIGINT, and when we receive either, we gracefully
exit the grpc loop.  If we also think that there aren't any container
filesystems in use, we attempt to do a clean shutdown of the storage
driver.

The test harness now waits for ocid to exit before attempting to delete
the storage root directory.

sandbox: Force netns unmount and removal when restoring 
ns.Close() will not remove and unmount the networking namespace
if it's not currently marked as mounted.
When we restore a sandbox, we generate the sandbox netns from
ns.GetNS() which does not mark the sandbox as mounted.

There currently is a PR open to fix that in the ns package:
https://github.com/containernetworking/cni/pull/342

but meanwhile this patch fixes a netns leak when restoring a pod.

sandbox: Create a symbolic link to the networking namespace 
In order to workaround a bug introduced with runc commit bc84f833,
we create a symbolic link to our permanent networking namespace so
that runC realizes that this is not the host namespace.

Although this bug is now fixed upstream (See commit f33de5ab4), this
patch works with pre rc3 runC versions.
We may want to revert that patch once runC 1.0.0 is released.

sandbox: Setup networking namespace before sandbox creation 
In order for hypervisor based container runtimes to be able to
fully prepare their pod virtual machines networking interfaces,
this patch sets the pod networking namespace before creating the
sandbox container.

Once the sandbox networking namespace is prepared, the runtime
can scan the networking namespace interfaces and build the pod VM
matching interfaces (typically TAP interfaces) at pod sandbox
creation time. Not doing so means those runtimes would have to
rely on all hypervisors to support networking interfaces hotplug.

sandbox: Use persistent networking namespace 
Because they need to prepare the hypervisor networking interfaces
and have them match the ones created in the pod networking
namespace (typically to bridge TAP and veth interfaces), hypervisor
based container runtimes need the sandbox pod networking namespace
to be set up before it's created. They can then prepare and start
the hypervisor interfaces when creating the pod virtual machine.

In order to do so, we need to create per pod persitent networking
namespaces that we pass to the CNI plugin. This patch leverages
the CNI ns package to create such namespaces under /var/run/netns,
and assign them to all pod containers.
The persitent namespace is removed when either the pod is stopped
or removed.

Since the StopPodSandbox() API can be called multiple times from
kubelet, we track the pod networking namespace state (closed or
not) so that we don't get a containernetworking/ns package error
when calling its Close() routine multiple times as well.

60123a77ce server: Export more container metadata for VM containers 
VM base container runtimes (e.g. Clear Containers) will run each pod
in a VM and will create containers within that pod VM. Unfortunately
those runtimes will get called by ocid with the same commands
(create and start) for both the pause containers and subsequent
containers to be added to the pod namespace. Unless they work around
that by e.g. infering that a container which rootfs is under
"/pause" would represent a pod, they have no way to decide if they
need to create/start a VM or if they need to add a container to an
already running VM pod.

This patch tries to formalize this difference through pod
annotations. When starting a container or a sandbox, we now add 2
annotations for the container type (Infrastructure or not) and the
sandbox name. This will allow VM based container runtimes to handle
2 things:

- Decide if they need to create a pod VM or not.
- Keep track of which pod ID runs in a given VM, so that they
  know to which sandbox they have to add containers.

server: make logDir configurable 
While logDir isn't currently used (until the conmon implementation
lands) it's probably not a great idea to hardcode our defaults. The main
issue with this setting is that the kubelet can override it at will.

server: make ImageStore configurable 
It's a bit odd to have ImageStore be part of the config and yet we don't
allow people to modify it. However, leave it out of the commented
version because it's currently unused.

 2016-10-25 03:25:17 +00:00

78528d9bd1 store infra container in sandbox 
infra container is used to implement the pod
sandbox, it should not be exported to user.

this patch stores infra container in sandbox
immediately, only the containers created by user
are stored into container store, this prevents user
from removing/stopping infra container incorrectly.

cd12a4acfe Can't use SELinux separation when sharing the host pid/ipc namespace 
SELinux will cause breakage when sharing these namespaces.  For example it
will block processes inside of the container from looking at the hosts /proc
in hosts Pid Namespace.  It will also block all access to semaphores and
shared memory defined outside of the pod.

server: create pause rootfs manually without Docker 
This lessens the Docker requirement for creating sandboxes (with the
requirement only existing for the actual image pulling that is done when
adding a container to a pod). The interface was chosen to match the
--conmon interface, so that the location of the pause binary can be
chosen by a user.
