2. Upgrade to logging
openshift_logging_install_logging=true
openshift_logging_es_cluster_size=2
openshift_logging_es_number_of_replicas=1
openshift_logging_es_number_of_shards=1
openshift_logging_es_memory_limit=2Gi
openshift_logging_es_nodeselector={"node-role.kubernetes.io/infra": "true"}

openshift_logging_use_ops=true
openshift_logging_es_ops_cluster_size=3
openshift_logging_es_ops_number_of_replicas=1
openshift_logging_es_ops_number_of_shards=1
openshift_logging_es_ops_memory_limit=2Gi
openshift_logging_es_ops_nodeselector={"node-role.kubernetes.io/compute": "true"}
openshift_logging_elasticsearch_storage_type=hostmount
