11 oc set volumes [OPTIONS]

16 Update volumes on a pod template
17 This command can add, update or remove volumes from containers for any
20 object that has a pod template (deployment configs, replication con‐
21 trollers, or pods). You can list volumes in pod or any object that has
22 a pod template. You can specify a single object or multiple, and alter
23 volumes on all containers or just those that match a given name.
24 If you alter a volume setting on a deployment config, a deployment will
27 be triggered. Changing a replication controller will not affect running
28 pods, and you cannot change a pod's volumes once it has been created.
29 Volume types include:
32 · emptydir (empty directory) default : A directory allocated
34 when the pod is created on a local host, is removed when the pod
35 is deleted and is not copied across servers
36 · hostdir (host directory): A directory with specific path on
38 any host (requires elevated privileges)
39 · persistentvolumeclaim or pvc (persistent volume claim): Link
41 the volume directory in the container to a persistent volume
42 claim you have allocated by name - a persistent volume claim is
43 a request to allocate storage. Note that if your claim hasn't
44 been bound, your pods will not start.
45 · secret (mounted secret): Secret volumes mount a named secret
47 to the provided directory.
48 For descriptions on other volume types, see ⟨https://docs.open‐
50 shift.com⟩
