The PersistentVolumeClaim Pvc-volume is invalid metadata name Invalid value Pvc-volume a DNS-1123 subdomain must consist of lower case alphanumeric characters

Question

Hi Guys,

I am trying to create one persistent volume claim in kubernetes. But it shows me the below error.

$ kubectl apply -f pvc.yml
The PersistentVolumeClaim "Pvc-volume" is invalid: metadata.name: Invalid value: "Pvc-volume": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')

Here I have created one yml file as given below.

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: Pvc-volume
  labels:
    name: Pvc-volume
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 3Gi

Hi@akhtar,

when you write yml code in kubernetes, you can't use capital letters in name and labels keyword. In above code, you have written Pod-volume in name and label section. So you have to change this value.

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-volume
  labels:
    name: pvc-volume
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 3Gi
