第 8 章 Pruning objects to reclaim resources
Over time, API objects created in OpenShift Container Platform can accumulate in the cluster’s etcd data store through normal user operations, such as when building and deploying applications.
Cluster administrators can periodically prune older versions of objects from the cluster that are no longer required. For example, by pruning images you can delete older images and layers that are no longer in use, but are still taking up disk space.
8.1. Basic pruning operations
The CLI groups prune operations under a common parent command:
$ oc adm prune <object_type> <options>
This specifies:
-
The
<object_type>to perform the action on, such asgroups,builds,deployments, orimages. -
The
<options>supported to prune that object type.
