If you are not familiar with the oc command, refer to OpenShift - Getting Started with the oc command.

The oc get pods command can be used to list the pods in the currently selected project.

~]# oc get pods
NAME         READY   STATUS     RESTARTS  AGE
foo-9mzm2    1/1     Running    0         8d
foo-vmzmz    1/1     Running    0         8d
bar-pflxc    1/1     Running    0         8d

The oc logs pod/<pod name> command can be used to view a pods log.

oc logs pod/foo-9mzm2

The output can be pipe to the tail command to only view the last 10 entries in the log.

oc logs pod/foo-9mzm2 | tail

The -f or --follow option can be used to stream the log in real time.

oc logs -f pod/foo-9mzm2

The -p or --previous flag can be used to see previous logs.

oc logs -p pod/foo-9mzm2

The -s or --since option can be used to only display logs in the last x seconds, x mintues, or x days.

oc logs -p pod/foo-9mzm2 --since=24h

Or, you could SSH onto node server1.example.com. Switch to the root user account.

sudo -i

The container will contain the POD log, like this.
