Description Sergio 2019-08-20 10:02:21 UTC
When the migration is quiescePods=true, cronjobs are not suspended and they continue spamming jobs.

How reproducible: always


Steps to Reproduce:
1. oc new-project cronjobtest
2. Create a helloworld cronjob

apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: hello
spec:
  schedule: "*/1 * * * *"
  jobTemplate:
    spec:
      template:
        spec:
          containers:
          - name: hello
            image: busybox
            args:
            - /bin/sh
            - -c
            - date; echo Hello from the cluster
          restartPolicy: OnFailure

3. Migrate the cronjobtest project with quiescePods=true


Actual results:

1. Cronjob is not suspended
oc get cronjob
NAME      SCHEDULE      SUSPEND   ACTIVE    LAST SCHEDULE   AGE
hello     */1 * * * *   False     1         14s             10m

2. Jobs continue to be scheduled
oc get pods
NAME                     READY     STATUS      RESTARTS   AGE
hello-1566294480-4j9g2   0/1       Completed   0          2m
hello-1566294540-7x78z   0/1       Completed   0          1m
hello-1566294600-kltmx   0/1       Completed   0          19s


Expected results:

1. Cronjob should be suspendend
  "oc get cronjob" should show "SUSPEND" with "true" value

2. "oc get pods" should show no new pods scheduled.
