Error

kubectl apply -f deployable-pvc.yaml
error: error validating "deployable-pvc.yaml": error validating data: ValidationError(PersistentVolumeClaim.spec): unknown field "phase" in io.k8s.api.core.v1.PersistentVolumeClaimSpec; if you choose to ignore these errors, turn validation off with --validate=false

Solution

The error you're seeing indicates that there's an incorrect or extraneous field phase within the spec section of your PVC definition in the deployable-pvc.yaml file.

The phase field is typically found under the status section of a PVC and not under the spec. You'll need to remove it to make the PVC definition valid.

Here's what you should do:

Open the deployable-pvc.yaml file in an editor.

Look for the phase field inside the spec section and remove it.

Save the file and try applying it again with:


$ kubectl apply -f deployable-pvc.yaml

If you want to automate the removal of the phase field (assuming you have yq installed), you can do:


$ yq eval 'del(.spec.phase)' deployable-pvc.yaml -i

This will modify the file in place, removing the phase field from the spec section. After that, you should be able to apply the file without any issues.
