[ghost]

Is this a BUG REPORT or FEATURE REQUEST?:

What happened: I submit the gcc-ttl.yaml , but after the workflow finished, it did not delete the workflow and pods

What you expected to happen:

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Environment:

• Argo version: v2.2.0

Same to me. After checking the workflow-controller log, it shows
E0921 18:21:51.030059 1 ttlcontroller.go:124] error deleting 'default/gc-ttl-5mgg4': workflows.argoproj.io "gc-ttl-5mgg4" is forbidden: User "system:serviceaccount:argo:argo" cannot delete workflows.argoproj.io in the namespace "default".

@jessesuen so here we need to do another rolebinding?

[jessesuen]

Oops, yes the role needs to be expanded to perform delete:

- apiGroups:
  - argoproj.io
  resources:
  - workflows
  - workflows/finalizers
  verbs:
  - get
  - list
  - watch
  - update
  - patch
  - delete # <<<< this needs to be added
