Create a new host group
-----------------------
* Create a new host group for ``flask_app`` in both inventories ``test`` and ``prod``

.. code-block:: yaml

	# file: test and prod
	[flask_app:children]
	web
	db

* Change the ``test`` and ``prod`` host group to use the new hostgroup ``flask_app``

.. code-block:: yaml

	# file: test
	[test:children]
	flask_app

.. code-block:: yaml

	# file: prod
	[prod:children]
	flask_app

* Create the variable ``flask_app_source`` only for the ``flask_app`` group with the value ``https://github.com/pstauffer/flask-mysql-app.git``

.. code-block:: yaml

	# file: group_vars/flask_app.yml
	---
	flask_app_source: https://github.com/pstauffer/flask-mysql-app.git


Extend your flask_app role
--------------------------
* Use the defined ``flask_app_source`` variable in your task file for the git checkout

.. code-block:: yaml

    # file: roles/flask_app/tasks/main.yml
	---
	- name: checkout flask_app
	  git:
	    repo: '{{ flask_app_source }}'
	    dest: /opt/flask_app
	    version: '{{ flask_app_version }}'

* Create a dependency on the already created ``python-pip`` role

.. code-block:: yaml

	# file: roles/flask_app/meta/main.yml
	---
	dependencies:
	  - python-pip

* Run the playbook ``deploy.yml`` for both inventories ``test`` and ``prod``

    ansible-playbook -i test deploy.yml

    ansible-playbook -i prod deploy.yml

* Verify the checkout of the correct version

.. code-block:: bash

    ssh web1.<firstname>.lab
    cd /opt/flask_app
    git describe --tags
    v1.0

    ssh web2.<firstname>.lab
    cd /opt/flask_app
    git describe --tags
    v1.1


Commit your changes

.. code-block:: bash

    git status
    git add roles/*
    git commit -m 'lab 11'
