The Ansible Galaxy is a web-based repository of Ansible roles and collections. Ansible is an open-source automation tool that can be used for configuration management, application deployment, and task automation. Ansible roles are collections of tasks, files, templates, and variables that can be reused across different playbooks and projects. Collections are similar to roles but can also contain modules, plugins, and other types of content.
The Ansible Galaxy allows users to search for and download pre-built Ansible roles and collections created by other users, which can save time and effort in developing and testing automation workflows. It also provides a platform for users to share and collaborate on their own roles and collections with the wider Ansible community.
The Ansible Galaxy can be accessed through a web interface or through the Ansible command-line interface (CLI) using the "ansible-galaxy" command. Users can browse and search for roles and collections by name, author, tag, or keyword. They can also rate, review, and fork existing roles and collections, or create and publish their own.
