##Working with ansible-vault

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.

This demonstrates that you can configure a Flask application through Flask-Script, without having to create a Flask instance or deal with circular dependencies. Note that Flask-Script's Manager accepts a factory function in place of a Flask app object.

Running:

python manage.py runserver

gives "Hello, world!" on http://localhost:5000/, while running:

python manage.py runserver -c development.cfg
