Pod cannot be terminated

[chiyiliao]

I create a pod with below config:

############

testpod.yaml

############
apiVersion: v1
kind: Pod
metadata:
name: test-job
spec:
serviceAccountName: saname
restartPolicy: Never
containers:
- name: test-pod
image: ubuntu
command:
- /bin/sleep
- "10"
resources:
limits:
cpu: 100m
memory: 128Mi
requests:
cpu: 100m
memory: 128Mi

############

CMD: kubectl -f testpod.yaml

After the sleep command finished, it does not terminated,

CMD: kubectl get pod
test-job 1/2 Running 0 5m26s

CMD: kubectl describe pod test-job
.
.

It seems like the update-gcp-id-token does not terminated.
Is it possible to terminate update-gcp-id-token after test-pod fininshed?

Thank you!
