oc ex dockergc [Options]
Perform garbage collection to free space in docker storage
If the OpenShift node is configured to use a container runtime other than docker, docker will still be used to do builds. However OpenShift itself may not manage the docker storage since it is not the container runtime for pods.
This utility allows garbage collection to do be done on the docker storage.
Only the overlay2 docker storage driver is supported at this time.
Run in single-pass mode with no effect.
The percent of disk usage after which image garbage collection is always run.
The percent of disk usage before which image garbage collection is never run. Lowest disk usage to garbage collect to.
Minimum age for a container or unused image before it is garbage collected. Examples: '300ms', '10s' or '2h45m'.
Options Inherited from Parent Commands
Allow a SignatureVerifier to use keys which are technically non-compliant with RFC6962.
log to standard error as well as files

Username to impersonate for the operation
Group to impersonate for the operation, this flag can be repeated to specify multiple groups.
Path to the file containing Azure container registry configuration information.
Comma-separated list of files to check for boot-id. Use the first one that exists.

The name of the kubeconfig cluster to use
location of the container hints file
The name of the kubeconfig context to use
Indicates the tolerationSeconds of the toleration for notReady:NoExecute that is added by default to every pod that does not already have such a toleration.
Indicates the tolerationSeconds of the toleration for unreachable:NoExecute that is added by default to every pod that does not already have such a toleration.
use TLS to connect to docker
path to trusted CA
path to client certificate
path to private key
a comma-separated list of environment variable keys that needs to be collected for docker containers
Only report docker containers in addition to root stats
DEPRECATED: docker root is read from docker info (this is a fallback, default: /var/lib/docker)
Whether to enable cpu load reader
Max length of time for which to store events (per type). Value is a comma separated list of key values, where the keys are event types (e.g.: creation, oom) or "default" and the value is a duration. Default is applied to all non-specified event types
Max number of events to store (per type). Value is a comma separated list of key values, where the keys are event types (e.g.: creation, oom) or "default" and the value is an integer. Default is applied to all non-specified event types
Interval between global housekeepings
Interval between container housekeepings
If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure
Path to the kubeconfig file to use for CLI requests.
Maximum number of seconds between log flushes
when logging hits line file:N, emit a stack trace
Whether to log the usage of the cAdvisor container
If non-empty, write log files in this directory
log to standard error instead of files
Comma-separated list of files to check for machine-id. Use the first one that exists.
Require server version to match client version
- -n, --namespace=""
If present, the namespace scope for this CLI request
The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests.
- -s, --server=""
The address and port of the Kubernetes API server
logs at or above this threshold go to stderr
Writes in the storage driver will be buffered for this duration, and committed to the non memory backends as a single transaction
use secure connection with database
Bearer token for authentication to the API server
The name of the kubeconfig user to use
- -v, --v=0
log level for V logs
Print version information and quit
comma-separated list of pattern=N settings for file-filtered logging
