We've got a few different Molecule scenarios which help you get up to speed fast in order to develop for a specific feature set. The primary requirement for those scenarios is that you have a working Docker installation.
If you'd like to validate one of the feature sets, you can simply run the following command on your local system with the name of the scenario you'd like
molecule converge -s <scenario>
If you want to expose your local instance to the outside world, or if you are running this on a remote system, you can use the HOST_IP environment variable.
HOST_IP=1.2.3.4 molecule converge -s <scenario>
