Code change:
Is this a BUG REPORT or FEATURE REQUEST?: /kind feature What happened: I need to know to which Pod(s) a PVC is being mounted to, without having to go through each Pod one by one checking the Volume mounts and the PersistentVolumeClaim. The kubectl describe pvc and get pvc, only tell you to which Persistent Volume the PVC is bound to, but not if is being used by a Pod(s) What you expected to happen: Add a new field in the describe or get that lists the pods that are using the PVC as a volume mount How to reproduce it (as minimally and precisely as possible): Have a PV/PVC bound and create a pod using a volume mount Anything else we need to know?: Not sure if this is only for Azure Disk, which is the Storage Class I am using. Environment: Kubernetes version (use ): 7 Cloud provider or hardware configuration: Azure OS (e.g. from /etc/os-release): Ubuntu 16.04 Kernel (e.g. ): 4 Install tools: Azure Kubernetes Services Others: -n/a
/sig storage
/sig cli
I think the kubectl describe can just construct this on the fly. Another angle is should we add this information to PVC object itself
That will be great, as right now the only way to correlate a PVC to a Pod is via a "describe" on the Pod.
I can work on a PR for this!

+1 for the feature. cc
How to find "what pods are using particular PVC through command line"
+1 for the feature.
this feature will be in Kubernetes 1.12
ok kubernetes 1.12 released, how to? which command?
Can someone point to the documentation or paste command to get the pods which have the PVC in use
see the associated PR to see an example usage of this The line in should show it.
Workaround for the meantime:
Thanks , this workaround is great for those people who still use old kubernetes version. However it will meet an error if the pod have no volumes, so I improves it by adding a to check whether the volumes exists or not.
python script to list pods with pvc in namespace(s): Is a part of a cli to set pods with velero/restic annotations. Hope it helps someone :)
For posterity... There is a Used By: field in the output of describe.
client-go didn't give this api... ,PodPVCIndex can solve the problem
Hi thanks worked for me ;) but I want to make it reverse my workarounds with adding after didn't worked do you have any ideas
$ kubectl describe pvc -A Used" Name: ocs-deviceset-lso-volumeset-0-data-1b45dn Namespace: openshift-storage StorageClass: lso-volumeset Used By: rook-ceph-osd-1--8fwpd Also useful ^
the reason it didn't work is because each return does, in point of fact, have a key defined for claimName. That key is just set to null value. So, what you'd actually want to do is test for nulls. As nice as answer is, it's a PITA to parse unstructured human-readable command output, as opposed to command output in a markup language that well known shell parsers like jq and yq can work with. Towards that end, because I had use of this, I came up with the following: That simple not null test at the end plucks out all your nulls. Obviously invert the last conditional if you want all the nulls, but you'll get all sorts of temp things that way that you probably won't care about.
