Build & Deploy Your Own Code in Your Homelab!

Build & Deploy Your Own Code in Your Homelab!

So you’re a software engineer or a developer who wants to self-host your own code in your own homelab? Well this is the tutorial for you! In this step-by-step guide we’ll walk through setting up a repo, building and testing our own code (with unit tests) in a self-hosted Gitlab CI runner in our CI pipeline, then we’ll build a Docker image and push it up to a container registry, then we’ll use kubectl in our CD pipeline to deploy our Docker container to our self-hosted kubernetes cluster! This all happens in a couple of minutes and then we’ll truly have continuous integration and continuous delivery in our homelab!
