Lab 12 - Solution

• Solution Project: https://github.com/pstauffer/flask-mysql-app/tree/master/lab12_solution

Important

This is just an example of a solution.

• You can also split the project into more roles and work with dependencies

  • mysql role (reusable for other projects)
  • gunicorn role (reusable for other projects)
  • flask role (reusable for other projects)
  • git role (reusable for other projects)

• Use fixed variables inside the roles in vars/main.yml

• Manage the whole my.cnf as template and add the ansible_managed header

• Verify, if the database already exists (to replace the ignore_errors)

• Use fixed versions for the packages (gunicorn, mysql-server, ...) to make sure, the application works with this versions

• put the RedHat / Debian part into own files redhat.yml / ``debian.yml

• Verify, if the application (gunicorn) is already running (to make the task idempotent)

• use tags
