Ansible Masterclass (Docker Lab)

A hands-on Ansible learning environment that uses Docker containers as SSH-enabled managed nodes. Organized into four progressive levels (basics, intermediate, advanced, multi-group), covering connectivity, packages, services, files, variables, loops, user management, handlers, data-driven tasks, and multi-play group-targeting deployments. Features a production-style site.yml using roles, both static and dynamic inventory (auto-discovers running containers), and comprehensive documentation. Two Ubuntu 22.04 containers with passwordless sudo are bootstrapped in seconds.
