Pod status.phase shall not transition from Succeeded to Pending.
(Note that this is dependent on timing of the deletion.)

I think this is the reason we are seeing multiple deployer pods running for DeploymentConfigs.

Version
$ oc version
oc v3.7.0-alpha.1+cba28e3-1203-dirty
kubernetes v1.7.6+a08f5eeb62
features: Basic-Auth

Server https://172.16.20.152:8443
openshift v3.7.0-alpha.1+39957d6-1203-dirty
kubernetes v1.7.6+a08f5eeb62
Steps To Reproduce
  1. docker pull centos:centos7
  2. oc observe pods --output=gotemplate -a '{{.}}'
  3. oc create -f ~/tmp/pod/pod.yaml; sleep 3; oc delete -f ~/tmp/pod/pod.yaml;
Current Result

Pod transitions from Succeeded to Pending after being deleted.

Expected Result

Once Pod reaches phase Succeeded it stays there.

Additional Information

$ cat ~/tmp/pod/pod.yaml

    env:

PLEG picks up on the container moving from running -> exited and the pod is marked as Succeeded.

However, then we failed to get the container status because it doesn't exist anymore, and the pod is seen as orphaned. PLEG goes from exited -> non-existent and a new status is created for the pod starting an Pending.

Opened upstream issue kubernetes/kubernetes#54499. We'll see if they want to revert or fix. Hopefully we'll get a quick response.
