Ansible Galaxy is the platform created by Ansible for its community. It allows its members to make and submit their own roles for other members to use, alter, upgrade, enhance, and optimize.
Ansible Galaxy is built to allow easier role submission by developers and role importation by users. When installing Ansible on the controller host, add in the ansible-galaxy command line. This command allows a Terminal interaction with the Ansible Galaxy repository.
Ansible Galaxy has given Ansible a huge advantage and allowed it to grow faster than any other automation tool. The existence of a supply of code written by experienced users is invaluable for less experienced users to easily access and learn from. This supply is composed of well-written Ansible-based projects and workflows.
