How to run flask app with ansible
<p>I am a new ansible user and I'm trying to run my flask application. Firstly, I would like to set the 'FLASK_APP' environment variable then use the command 'flask run'. In the purpose of doing this, my ansible tasks looks like this:</p>

<pre><code>- name: install flask with pip
  pip: name=flask
- name: set environnement
  shell: "export FLASK_APP=/var/www/main.py"
- name: start flask
  shell: "flask run"
</code></pre>
