Ansible Role Symlinks

Symlinks roles that are part of the Gas Station project to a location that Ansible can digest

Overview

Install Doctor was previously called Gas Station. It was also Ansible based. Some of the features that Install Doctor provides are made available via Ansible roles that Gas Station provides. This script symlinks Gas Station's roles so that they can be leveraged by Install Doctor.

Some of the roles that Gas Station provides are not available via Ansible Galaxy yet. This script symlinks Gas Station roles to an Ansible Galaxy / Ansible friendly location.

Ansible Installation

If Ansible is not already installed, this script will also install Ansible and all the necessary requirements using pipx. This script must run before the install-packages script because some of the Ansible roles might be leveraged by it.

TODO

Move installation logic into the ZX installer so that Ansible and its dependencies are only installed when required
Remove Ansible dependency completely
