Installation

Ansible is a Python application so it can be installed using Pip or Homebrew. To use Pip;

$ sudo pip install ansible

Once it has installed it should be possible to run the following command from $TIS-DEVOPS

$ ansible jenkins -i ansible/inventory/build -m ping
10.1.0.4 | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}

Creating a new stack

1. Check out $TIS-DEVOPS
2. Create a new directory under docker/stacks/:stack_name
3. Add a docker-compose.yml in that new directory. If your application needs environment variables then use an env_file section, i.e. 

   env_file:
     - ./:stack_name.env

   
   

4. Create new playbook under ansible/ directory that matches your service name

5. Add the hosts to the Ansible inventory file for platforms you are targetting.

6. Create a Jinja template under ansible/roles/docker_compose/templates/:stack_name.env.j2

7. Commit and push your changes to Github.
8. Create a deploy job in Jenkins by copying the 'revalidation-dev-deploy' job and changing the export STACK=revalidation to match your stack name.
