Any leads are really appreciated.

Hi, can you tell which kubernetes version are you using? by using following command you can get the version kubectl version As of v1.9 you need to use apps/v1beta1 – Header

Answer 1

Your error message should be like this:

error: error validating "couch_persistant_deploy.yaml": error validating data: ValidationError(Deployment.spec.template.spec.volumes[0]): unknown field "claimName" in io.k8s.api.core.v1.Volume; if you choose to ignore these errors, turn validation off with --validate=false

See, error message is specific: unknown field "claimName" in io.k8s.api.core.v1.Volume

In your Deployment you need to nest claimName value one level deep inside of its persistentVolumeClaim key, because non-list values must be indented inside their keys (only keys starting a list such as name here - which begins with a dash - don't have to be indented):

  volumes:
  - name: task-pv-storage
    persistentVolumeClaim:
      claimName: task-pv-claim  # fix is here

But you did

  volumes:
  - name: task-pv-storage
    persistentVolumeClaim:
    claimName: task-pv-claim  # invalid

Which makes your Deployment object invalid
