k8s Terminating Namespace

일반적으로는 K8s Terminating namespace 강제 삭제로 삭제된다.

아래 예시는 그렇게 해도 삭제가 안되는 사례

$ kubectl get ns | grep Terminating
dind              Terminating   581d

$ kubectl describe ns dind
Name:         dind

No resource quota.

No LimitRange resource.

$ kubectl get ns dind -oyaml
apiVersion: v1
kind: Namespace
metadata:
  annotations:
    cattle.io/status: '{"Conditions":[{"Type":"ResourceQuotaInit","Status":"True","Message":"","LastUpdateTime":"2024-02-19T14:12:18Z"},{"Type":"InitialRolesPopulated","Status":"True","Message":"","LastUpdateTime":"2024-02-19T14:12:18Z"}]}'
    lifecycle.cattle.io/create.namespace-auth: "true"
  creationTimestamp: "2022-08-20T11:28:15Z"
  deletionTimestamp: "2024-03-16T10:56:40Z"
  finalizers:
  - controller.cattle.io/namespace-auth ###
...

→ kubectl edit ns 명령어로 finalizer를 제거했더니 삭제되었다.
