+# This code below is designed to support two specific scenarios for
+# using Elasticsearch and Kibana with Kubernetes. In both cases the
+# environment variables PROXY_HOST and PROXY_PORT identify the instance
+# of Elasticsearch to be used by Kibana. The default value for ES_HOST
+# identifies the location that served the Javascript for Kibana and
+# the default value of ES_PORT 5601 is the port to be used for connecting
+# to Kibana. Both of these may be overriden if required. The two scenarios are:
+# 1. Elasticsearch and Kibana containers running in a single pod. In this
+#    case PROXY_HOST is set to the local host i.e. 127.0.0.1 and the
+#    PROXY_PORT is set to 9200 because Elasticsearch is running on the
+#    same name as Kibana. If KIBANA_IP is the external IP address of
+#    the Kubernetes Kibna service then all requests to:
+#       KIBANA_SERVICE:$ES_PORT/elasticsearch/XXX
+#    are proxied to:
+#       http://127.0.0.1:9200/XXX
+# 2. Elasticsearch and Kibana are run in separate pods and Elasticsearch
+#    has an IP and port exposed via a Kubernetes service. In this case
+#    the Elasticsearch service *must* be called 'elasticsearch' and then
+#    all requests sent to:
+#       KIBANA_SERVICE:$ES_PORT/elasticsearch/XXX
+#    are proxied to:
+#       http://$ELASTICSEARCH_SERVICE_HOST:$ELASTICSEARCH_SERVICE_PORT:9200/XXX
+# The proxy configuration occurs in a location block of the nginx configuration
+# file /etc/nginx/sites-available/default.
