OpenStack Watcher

Ansible Role that installs and configures OpenStack Watcher.

This role will install the following:

• watcher-api
• watcher-decision-engine
• watcher-applier

The role will configure Watcher, but does not provision RabbitMQ or MariaDB.

This role is intended to work primarily with OpenStack-Ansible, but consuming this role by setting the appropriate variables should be possible. See the tests/test-install-watcher.yml for example playbook.
