Why This Project?

The motivation behind this Docker Ansible Lab project is to eliminate the headaches associated with creating a lab environment for Ansible practice. The traditional setup demands a robust machine capable of running at least three VMs, with various configurations such as network establishment and SSH communication. This project aims to simplify the process by allowing users to set up a scalable lab environment within Docker, with minimal configuration requirements.

Project Goals

The primary goal of the Docker Ansible Lab project is to enable users to effortlessly set up a lab environment within a Docker container. Unlike traditional setups, this project offers scalability, allowing users to create more than three machines with ease. The emphasis here is on minimizing the setup steps and allowing users to dive straight into Ansible without worrying about the intricacies of lab configuration.
