Pod Status

The most complete information set is generated by "oc get -o yaml pod ..." and "oc describe pod ...":

oc [-n <project-name>] [[oc get#pods|get pods]
oc [-n <project-name>] -o yaml get pod] <pod-name>
oc [-n <project-name>] describe pod <pod-name>
oc [-n <project-name>] describe pod/<pod-name>
oc [-n <project-name>] edit pod/<pod-name>

Monitor Pod's Logs

oc logs -f <pod-name>

Update a Pod Defintion

Stopping Pods

A pod can be stopped by deleting its associated "pod" object:

oc delete pod/logging-fluentd-3kz30

The controller (either replication or DamonSet) will detect that the pod is missing and it will start a new one.
