There's a lot more knobs and bolts to set, which you can find in the defaults/main.yml

Testing - Molecule

This project comes with a molecule configuration. Please see ./molecule/README.md

Examples:

molecule test

Testing - Vagrant

This project comes with a Vagrantfile, this is a fast and easy way to test changes to the role, fire it up with vagrant up

See vagrant docs for getting setup with vagrant

Once your VM is up, you can reprovision it using either vagrant provision, or ansible-playbook tests/playbook.yml -i vagrant-inventory

If you want to toy with the test play, see tests/playbook.yml, and change the variables in tests/vars.yml

If you are contributing, please first test your changes within the vagrant environment, (using the targeted distribution), and if possible, ensure your change is covered in the tests found in .travis.yml
