The biggest difference between my setup and your setup might be our configuration files. In Unix world we call them dotfiles. Dotfiles are files whose filename starts with a dot and hidden by default in our file managers.

I always love the idea of GitOps, where everything I have in a git repo represents the current state of my application. But not everything are made for GitOps, so we have to sort of “make it work”. In this post, I will show you how I manage to GitOps my Home Assistant configurations. Spoiler, this is hacky and messy at the same time, so please bear this in mind before continuing.

Having an up-to-date Kubernetes node is important, especially security updates. Sometimes an update requires a reboot to take effect, and you don’t want to keep checking them manually. In this post, I will share about how I automate my Kubernetes nodes to reboot when necessary using Kured.

Sometimes there are values that you want to use multiple times in your manifest files. Usually, we define them using a config map or secret and we either mount them as a file or environment variable. This is easy if you don’t use GitOps and have a small amount of pods. Also, having a single configmap and secret will clean up a lot of mess out of your cluster, and this is what variable substitution will do for you. I find this really useful especially for sensitive information you don’t want people all around the world to see. In this post, I will show you how I do variable substitution using Flux GitOps tool.

Following my previous post about Kubernetes management using Flux, this post will cover secret management using SOPS and age. SOPS is a tool to encrypt and decrypt text files while age is the encryption tool that is simple, modern, and secure.

GitOps is currently the most popular way to manage your services. It’s sort of what DevOps is but with Git. To put it in a simple way, it is a practice where you manage everything through git. Whatever you have in your git repository is what your cluster current state is. Because GitOps is so popular there are a lot of new tools focusing on GitOps right now, and Flux is one of them. In this post I will give you a glance on how I manage my Kubernetes manifests using Flux.

In this part, we are going to setting up Docker on Raspberry Pi. Here’s what you will get if you follow through the end of the tutorial:
Before we get our hands on setting up docker on our Raspberry Pi, let’s first do a system update. If you are on Manjaro, the command will be:
