Getting Started with Ansible

Ansible is a system for executing commands on remote systems. It allows a declarative approach - so if you run a playbook (the system configuration files are called playbooks) that says a system has a Docker container running Jellyfin, Ansible will check if that’s true, and if not, make it so. Ansible is best used when you have a large number of systems to maintain, but even with a small number, it serves to document systems as well as to automate their creation.
