argo-workflows: Pods do not get deleted on success/failure

Checklist:

• I’ve included the version.
• I’ve included reproduction steps.
• I’ve included the workflow YAML.
• I’ve included the logs.

What happened: I am trying to implement GC strategy to delete pods automatically after workflow is done. However, podsdon’t get deleted. I’ve tried with all strategy options (see), but result is the same.

What you expected to happen:

Workflows should be deleted after Success or failure.

How to reproduce it (as minimally and precisely as possible): Submit following workflow with argo CLI.

Anything else we need to know?:

Workflow.yaml

apiVersion: argoproj.io/v1alpha1
kind: Workflow                  # new type of k8s spec
metadata:
  generateName: nirav-test-    # name of the workflow spec
spec:
  podGC:
    strategy: OnPodCompletion
  entrypoint: pod-gc-strategy          # invoke the whalesay template
  templates:
  - name: pod-gc-strategy
    steps:
    - - name: fail
        template: fail
      - name: succeed
        template: succeed

  - name: fail
    container:
      image: alpine:3.7
      command: [sh, -c]
      args: ["exit 1"]

  - name: succeed
    container:
      image: alpine:3.7
      command: [sh, -c]
      args: ["exit 0"]
