Section Number and Name: Deploying the EFK Stack

Describe the issue: In the referenced section, the is a figure with output of command "oc get pods -w". One of the pods that's visible in the output is logging-curator-1541129400-l5h77. This is however quite misleading. The reason is that curator pod is not created alongside other pods of EFK stack by design. Instead, the pod is controlled by OpenShift cronjob that can be acquired like this: oc get cronjob -n openshift-logging -l component=curator.
By default, the actual pod is only created once a day at 3:30 AM and does its thing. Then it stays in the pod listing with Completed status until deleted. So, to bottom line it: It would be very big coincidence if the user actually saw what the documentation displays. They will see such output only if they run their deployment around 3:30 AM. In all the other cases, they won't see the curator pod at all and might be confused why that happens.

Suggestions for improvement: I think it would be good to remove the curator pod from the output and ideally also explain that user should not worry if they don't see it, since it's controlled by a cronjob. We could also reference section about curator where the implementation is explained:

Additional information: I am reporting this bug after experienced such troubles myself. You can see BZ1684053 for reference.
