External components

By default, plain docker-compose up, assuming both pipelines are included, will start containers for following services:

• MySQL
• Keystone
• ElasticSearch
• Zookeeper
• Kafka

However, each of them is treated, at the same time as the dependency for Monasca, hence can be externalized with the help of appropriate environmental variables.

The following guide presents how to achieve that.

Using external OpenStack Keystone

By default monasca-docker uses Keystone stored in separate container. But if you want to use an external Keystone you need to overwrite some environment variables in specific containers.

Remove the keystone image initialization and all references to this image from depends_on, from other services, from docker-compose.yml and log-pipeline.yml files.

Example configuration taking into account usage of Keystone aliases instead of ports when overwriting environment variables:

docker-compose.yml

In agent-forwarder and agent-collector:

environment:
  OS_AUTH_URL: http://192.168.10.6/identity/v3
  OS_USERNAME: monasca-agent
  OS_PASSWORD: password
  OS_PROJECT_NAME: mini-mon

In alarms:

environment:
  OS_AUTH_URL: http://192.168.10.6/identity/v3
  OS_USERNAME: mini-mon
  OS_PASSWORD: password
  OS_PROJECT_NAME: mini-mon

In monasca:

environment:
  KEYSTONE_IDENTITY_URI: http://192.168.10.6/identity
  KEYSTONE_AUTH_URI: http://192.168.10.6/identity
  KEYSTONE_ADMIN_USER: admin
