flask-ansible

Usage

First you need to create an SSH key pair, copy the public key on remote hosts and copy the private key to the empty id_rsa file in this project. Build and run the sample application on your workstation:

docker build -t flask-ansible .
sudo docker run -p 80:80/tcp flask-ansible

Now open http://localhost on your browser, or just use curl to call the only method on the sample application:

curl 'localhost/?host=srvX.example,srvY.example'

That command uses Ansible to run these two tasks on srvX.example and srvY.example hosts:

27 ...
28 dict(action=dict(module='shell', args="hostname -f")),
29 dict(action=dict(module='yum', args="name=nano, state=latest"))
30 ...

This is a sample JSON response from the application:

Development

Use Flask documentation for more information on developing Flask applications. You can use any Ansible module to write tasks in your application. If you develop new Ansible modules just put them in application/library directory in this project and start using them in the application.
