#!/usr/bin/expect -f
#
# This script sets the user passwords for elastic,apm_system,kibana,kibana_system,logstash_system,beats_system,remote_monitoring_user
# It uses the environment variables to set these passwords in the provided container id
#
# Requirements:
# ARGUMENTS:
# 0 - the elastic-search container id (eg. set-elastic-passwords.exp 141aba142)
# 
# ENVIRONMENT VARIABLES:
# ES_ELASTIC - The elastic search super-user password
# ES_APM_SYSTEM - The password for the user the APM server uses when storing monitoring information in Elasticsearch.
# ES_KIBANA_SYSTEM - The password for the user Kibana uses to connect and communicate with Elasticsearch.
# ES_LOGSTASH_SYSTEM - The password for the user Logstash uses when storing monitoring information in Elasticsearch.
# ES_BEATS_SYSTEM - The password for the user the Beats use when storing monitoring information in Elasticsearch.
# ES_REMOTE_MONITORING_USER - The password for the user Metricbeat uses when collecting and storing monitoring information in Elasticsearch. It has the remote_monitoring_agent and remote_monitoring_collector built-in roles.
