Goal:
Run the unifi controller as container on my home K3s cluster.
Introduction The synology D916+ can run a docker application packed in a single container, which I found quite convenient to host a couple of applications in my home network:
The unifi controller, to manage our two Unifi Access Points The Logitech Media Server - yes, I still own several squeezeboxes I wouldn’t change for anything :D Home Assistant Planning to add further applications - and having in mind a setup where the logs from some of the home applications are fed into a elasticsearch cluster later - I decided to move them to Kubernetes, which it meant to reactivate my K3s cluster, which I had installed on a Raspberry Pi 4 a while ago - see my previous post:
Goal:
Self-host Nextcloud on Kubernetes and use it as server-side for the /e operating system
Nextcloud offers an on-premises content collaboration platform, which is open-source and free. The Nextcloud server is written in the PHP and JavaScript scripting languages.
The /e/ ROM is a fork of Android (more precisely from LineageOS).
See previous post to see how to install the OS on a LG G3 and my efforts to self-host the /e server beta version.
Goal:
Set up a minimal Kubernetes cluster on Rapberry Pi 4.
I ordered a new Raspberry Pi 4 a couple of days ago. I already use one at work for automated testing and I think it’s pretty cool, but I actually wasn’t sure what I wanted it for. After giving it a thought, I decided to install Rancher’s K3S distribution on it, turning it to a convenient, low-power-consumption, single-node K8s distribution I can use as a playground.
Goal:
Deploy cozy on my homemade kubernetes cluster
The K8s homemade cluster on baremetal was meant to be just an exercise and not a permanent setup. Still, I needed to find something to deploy on it :)
I decided to try out Cozy Cloud deploying software and dependencies as containers in my K8s cluster.
Cozy is a personal, free and self-hostable cloud platform, written in Go.
Milestones Pre-requisites: make sure the infrastructure is ready Cozy Software: installation, dependencies and configuration Docker Images: which one are available and which new ones we need K8s Configuration: write manifests for deployment in the cluster Cozy instance: create a new cozy instance and test it 1.
Goal:
Configure DNS, so applications running on the K8S cluster are reachable from the internet and TLS-protected
Setting up a home made kubernetes cluster is quite straightforward. However, for deploying applications or services accessible from the internet, the configuration capabilities of the standard provider’s internet boxes are usually too limited.
In particular I had the issue of the internal host resolution. My internet box wasn’t able to properly route requests to the own external IP address from inside the internal network.
Goal:
Set up a home Kubernetes cluster with old hardware: 1 Master and 1 Worker
Tasks:
Find old hardware Install Ubuntu Server 18.04 LTS Set up Master Node Set up Worker Node Service Account Install helm Install ingress Install cert-manager Cluster Issuer (Let’s Encrypt) Storage 1. Find old hardware Since kubernetes is lightweight and can run almost everywhere, I decided to go down to the cellar and rescue some old PC which I thought could still work for this.
