🧪 Build a Local Ansible Lab with Docker (No VMs Needed)

#devops #docker #ansible

I recently put together a lightweight Ansible lab using Docker — and it’s been a super clean way to test playbooks without spinning up virtual machines or using the cloud.

Whether you're learning Ansible or just want a disposable playground, this setup gives you:

⚙️ What's Inside?

  • 🐧 Three Ubuntu containers (managed nodes)
  • 🔐 SSH enabled (user: root, password: root)
  • 🐍 Python pre-installed for Ansible modules
  • 🌐 Docker network named ansible
  • 🎯 Port forwarding so you can SSH from your local machine

🚀 Why I Built This

I wanted a quick, minimal lab that would let me focus on learning Ansible without spending time managing VMs or cloud resources. With Docker Compose, I just run:

docker-compose up --build -d
Enter fullscreen mode Exit fullscreen mode

…and I’m ready to automate.

🧪 Try It Out

Here’s what you need to do:

  1. Clone the repo 
   git clone https://github.com/sheharyar566/ansible-docker-lab.git
   cd ansible-docker-lab
Enter fullscreen mode Exit fullscreen mode
  1. Start the lab 
   docker-compose up --build -d
Enter fullscreen mode Exit fullscreen mode
  1. SSH into a node 
   ssh root@localhost -p 2221
Enter fullscreen mode Exit fullscreen mode
  1. Create an inventory file for Ansible and run: 
   ansible -i inventory.ini all -m ping
Enter fullscreen mode Exit fullscreen mode
