This project was created to help you build your own home lab where you can test your applications and configurations without breaking your workstation so you can learn on cheap devices without paying for more expensive cloud services.

The project contains code written for the tutorial, but you can also use parts of it if you refer to this repository.

Note: The inventory.yml file is not shared since that depends on the actual environment so it will be different for everyone. If you want to learn more about the inventory file, watch the videos on YouTube or read the written version on https://dev.to. Links in the video descriptions on YouTube.

You can also find an example inventory file in the project root. You can copy that and change the content so you will use your IP addresses and usernames.

cp inventory-example.yml inventory.yml

Optionally, if you want to start an SSH agent, run:

ssh-agent $SHELL

If you generated an SSH private key at ~/.ssh/ansible the it will be added automatically when you souce the homelab env scripts. Otherwise you need to run:

ssh-add $PATH_OF_THE_SSH_PRIVATE_KEY

Use the actual path of the SSH private key instead of the variable.

Since Ansible 8.0.0 requires a recent Python version, if you are on Ubuntu 22.04 for example you can install Nix and run the following command to create the Python environment using Python 3.11:

./create-nix-env.sh venv

or

./create-nix-env.sh venv-linux

If you created a python virtual environment with the name "venv", you can activate it using

source homelab-env.sh

Override the HOMELAB_ENV variable to customize the environment:

HOMELAB_ENV=custom-env source homelab-env.sh

If you want venv-linux on linux and venv-darwin on macOS, you can run

source homelab-env-os.sh
