positive.code: |*_MODE_* (default: *install*)

  Running the deployer creates a deployer pod and prints its name.
  
  . Wait until the pod is running. It may take several minutes for {product-title}
  to retrieve the deployer image from the registry.

  [NOTE]
  ====
  The logs for the *openshift* and *openshift-infra* projects are automatically aggregated and grouped into the *.operations* item in the Kibana interface.
  
  The project where you have deployed the EFK stack (*logging*, as documented here) is _not_ aggregated into *.operations* and is found under its ID.

  You can watch its progress with:

  ----
  $ oc get pod/<pod_name> -w
  ----
  +
  It should eventually enter Running status and end in Complete status.
  If it seems to be taking too long to start, you can retrieve more details about
  the pod and any associated events with:
  +
  ----
  $ oc describe pod/<pod_name>
  ----

  You can also check the logs if the deployment does not complete successfully:

  ----
  $ oc logs -f <pod_name>

  If you set `*enable-ops-cluster*` to `true` for the deployer, Fluentd
  is configured to split logs between the main ElasticSearch cluster
