    openshift_logging_es_pvc_dynamic=true
    openshift_logging_es_pvc_size=5G
    openshift_logging_es_cluster_size=3
    openshift_logging_es_memory_limit=4G
    openshift_logging_es_number_of_replicas=2
    openshift_logging_es_nodeselector={'region' : 'infra'}
    openshift_logging_curator_nodeselector={'region' : 'infra'}
    openshift_logging_kibana_nodeselector={'region' : 'infra'}
  2. To verify, execute the following command:
    # oc get pods -n openshift-logging
