Ansible for the Homelab — Series Introduction
This is a practical, hands-on series for anyone who manages more than one machine at home and is tired of repeating the same manual steps. We'll use Ansible to automate everything from initial server setup to deploying real services - including secrets management, Docker, Cloudflare tunnels, and your own code.
No prior Ansible experience required. If you can SSH into a Linux box and edit a YAML file, you're ready.
What is Ansible?
Ansible is an open-source automation tool that lets you describe your infrastructure as code. Instead of SSHing into each machine and running commands by hand, you write a playbook once and run it against as many hosts as you need.
It's agentless - nothing installs on your servers. Ansible connects over SSH, runs your tasks, and disconnects. That makes it easy to adopt incrementally alongside whatever you're already doing.
What We'll Cover
-
Part 1 - Installation and Your First Inventory. Install Ansible, define your hosts, and verify connectivity across your lab.
-
Part 2 - Your First Playbook. Automate initial server setup - users, SSH keys, and baseline packages.
-
Part 3 - Roles and Structure. Organize playbooks into reusable roles so your repo stays clean as it grows.
-
Part 4 - Ansible Vault. Storing secrets safely so you can commit your code without exposing passwords.
-
Part 5 - Deploying Services with Docker. Use Ansible to install Docker and deploy containerized services across your lab.
-
Part 6 - Cloudflare Integration. Automate DNS records and Cloudflare tunnel configuration directly from your playbooks.
-
Bonus - Deploying Your Own Code. For developers: package your own APIs and services as Docker containers and deploy them to dev and prod with a single playbook.
Prerequisites
- One or more Linux machines you can SSH into (VMs, Raspberry Pis, or bare metal all work)
- A control node - your laptop or a dedicated machine - running macOS or Linux
- Basic comfort with the command line and YAML
This site runs on the same infrastructure we'll be building. Every role, playbook, and pattern in this series comes from a working homelab.
Let's get started.
