Installing kubectl plugin with krew: unused-pvc

2 min read

Krew is a plugin manager for kubectl (v1.12 or higher), we will need to install krew first. To be able to test the unused-volumes plugin we will have to create a PersistentVolumeClaim that we won't use on any pot:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: demo-pvc
  namespace: kube-system
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
