List Pods for a Project
oc get projects oc get -n <project-name> pods
List Pods on Nodes
oadm manage-node <node-name> --list-pods
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>
Execute Commands in Containers
oc rsh <pod-id> <command>
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.
