# Ansible Role Symlinks
|
|
|
|
Symlinks roles that are part of the [Gas Station](https://github.com/megabyte-labs/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
|
|
|
|
|
