NAME
crio.conf - CRI-O configuration file
DESCRIPTION
The CRI-O configuration file specifies all of the available command-line options for the crio(8) program, but in a TOML format that can be more easily modified and versioned.
FORMAT
The [TOML format][toml] is used as the encoding of the configuration file. Every option and subtable listed here is nested under a global "crio" table. No bare options are used. The format of TOML can be simplified to:
[table]
option = value
[table.subtable1]
option = value
[table.subtable2]
option = value
CRIO TABLE
The crio table supports the following options:
root="" CRIO root dir (default: "/var/lib/containers/storage")
runroot="" CRIO state dir (default: "/var/run/containers/storage")
storage_driver="" CRIO storage driver (default is "devicemapper")
storage_option=[] CRIO storage driver option list (no default)
CRIO.API TABLE
listen="" Path to crio socket (default: "/var/run/crio.sock")
CRIO.RUNTIME TABLE
conmon="" Path to the conmon executable (default: "/usr/local/libexec/crio/conmon")
conmon_env=[] Environment variable list for conmon process (default: ["PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin",])
pids_limit="" Maximum number of processes allowed in a container (default: 1024)
runtime="" OCI runtime path (default: "/usr/bin/runc")
selinux=true|false Enable selinux support (default: false)
signature_policy="" Path to the signature policy json file (default: "", to use the system-wide default)
seccomp_profile="" Path to the seccomp json profile to be used as the runtime's default (default: "/etc/crio/seccomp.json")
apparmor_profile="" Name of the apparmor profile to be used as the runtime's default (default: "crio-default")
CRIO.IMAGE TABLE
default_transport A prefix to prepend to image names that can't be pulled as-is (default: "docker://")
image_volumes="" Image volume handling ('mkdir' or 'ignore') (default: "mkdir")
insecure_registries="" Enable insecure registry communication, i.e., enable un-encrypted and/or untrusted communication.
List of insecure registries can contain an element with CIDR notation to specify a whole subnet. Insecure registries accept HTTP and/or accept HTTPS with certificates from unknown CAs.
Enabling --insecure-registry is useful when running a local registry. However, because its use creates security vulnerabilities it should ONLY be enabled for testing purposes. For increased security, users should add their CA to their system's list of trusted CAs instead of using --insecure-registry.
pause_command="" Path to the pause executable in the pause image (default: "/pause")
pause_image="" Image which contains the pause executable (default: "kubernetes/pause")
registries="" Comma separated list of registries that will be prepended when pulling unqualified images
CRIO.NETWORK TABLE
network_dir="" Path to CNI configuration files (default: "/etc/cni/net.d/")
plugin_dir="" Path to CNI plugin binaries (default: "/opt/cni/bin/")
