Aim

To idempotently automate the installation and configuration of a Mattermost server using Ansible and Baker.

The code does the following:

Creates one VM each for an Ansible server and a Mattermost server. The database will reside on the same server as Mattermost.
Runs an Ansible playbook on the Ansible server to setup the following on the Mattermost server:
- Update the Linux system.
- Install and configure MySQL.
- Install and configure Mattermost

The functionality has been distributed into three roles respectively for each of the configuration tasks mentioned above that Ansible has to perform:

Go inside the mattermost-srv folder.
Run baker bake in the terminal to setup the mattermost VM.
Go inside the ansible-srv/group_vars folder.
Delete mattermost.yml file.
Go up one level to ansible-srv.
Run baker bake to setup the configuration server.
Since we need to use anisble-vault, we are going to have to ssh into the VM. Run baker ssh to ssh into the Ansible server.
Run `ansible-vault create mattermost.yml' and give a password for the vault. This will open an editor.
In the editor give vaules for admin_pwd: your_mattermost_admin_password and mysql_pwd: your_mysql_database_password on 2 separate lines. Save and exit.
Run mv mattermost.yml /ansible-srv/playbook/group_vars to move the new vault file to the playbook.
Exit the ssh session.
Run baker install-mm to run the ansible playbook.
Navigate to 192.168.33.100:8065 to test the server.
Admin username is admin. Password will be the value set for admin_pwd.
You can also signup as a new user as that has been enabled in the config.json.
The admin can then add the new user to a team and send them notifications.
Run baker install-mm again to verfiy that the playbook is idempotent and exisitng users and teams aren't deleted.
