On GKE prints the list of Kubernetes volumes to GCP persistent disk name mappings using kubectl
|
|
|
|
|
|
|
|
Any args are passed straight to kubectl as is
|
|
|
|
|
|
|
|
Output:
|
|
|
|
|
|
|
|
<namespace> <pvc_name> <kubernetes_persistent_volume> <gcp_persistent_disk> <zone>
|
|
|
|
|
|
|
|
This is useful to investigate GCP disks when testing disk resizing
