# 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_LOGGING_SERVICE:$ES_PORT/elasticsearch/XXX
|
|
# are proxied to:
|
|
# http://127.0.0.1:9200/XXX
|
|
# 2. Elasticsearch and Kibana are run in separate pods and Elasticsearch
|
|
# has an IP and port exposed via a Kubernetes service. In this case
|
|
# the Elasticsearch service *must* be called 'elasticsearch' and then
|
|
# all requests sent to:
|
|
# KIBANA_LOGGING_SERVICE:$ES_PORT/elasticsearch/XXX
|
|
# are proxied to:
|
|
# http://$ELASTICSEARCH_LOGGING_SERVICE_HOST:$ELASTICSEARCH_LOGGING_SERVICE_PORT:9200/XXX
|
|
# The proxy configuration occurs in a location block of the nginx configuration
|
|
# file /etc/nginx/sites-available/default.
