Role Name
=========
A brief description of the role goes here.
Requirements
------------
Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
A role that installs the Bluecloud uFish stack
Role Variables
--------------
A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
The most important variables are listed below:
``` yaml
bc_ufish_compose_dir: '/srv/bc_ufish_stack'
bc_ufish_docker_stack_name: 'bluecloud-ufish'
bc_ufish_docker_service_server_name: 'bc-ufish-server'
bc_ufish_docker_service_client_name: 'bc-ufish-client'
bc_ufish_docker_server_image: 'tommasinopierfrancesco/ufish-server'
bc_ufish_docker_client_image: 'tommasinopierfrancesco/ufish-client'
bc_ufish_docker_network: 'bc_ufish_net'
# IMPORTANT. Set it to True for the server that is going to host the DB
bc_ufish_behind_haproxy: True
bc_ufish_haproxy_public_net: 'haproxy-public'
# DB
bc_ufish_db_docker_host: 'localhost'
bc_ufish_db_host: 'ufish-mysql'
bc_ufish_db_port: 3306
bc_ufish_mysql_root_password: 'set it in a vault file'
bc_ufish_db_pwd: 'set it in a vault file'
bc_ufish_db_name: 'bc_ufish'
bc_ufish_db_user: 'bc_ufish_u'
bc_ufish_db_volume: 'bc_ufish_db_data'
bc_ufish_db_constraints: 'node.labels.ufish_db_data == bc_ufish'
```
Dependencies
------------
A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.
Example Playbook
----------------
Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
- hosts: servers
roles:
- { role: username.rolename, x: 42 }
A docker swarm cluster is required
