A lot of people have asked me about my home Kubernetes cluster, and so I have decided to put together a series of blog posts about the architecture. I’m going to split it into sections, with each section focusing on a specific area. If you haven’t read the other parts of this guide, I recommendContinue reading “Kubernetes Homelab Part 1: Overview”

Using TrueNAS to provide persistent storage for Kubernetes
A while ago I blogged about the possibilities of using Ceph to provide hyperconverged storage for Kubernetes. It works, but I never really liked the solution so I decided to look at dedicated storage solutions for my home lab and a small number of production sites, which would escape the single-node limitation of the MicroK8sContinue reading “Using TrueNAS to provide persistent storage for Kubernetes”
Load-balancing Ingress with MetalLB on MicroK8s
Out of the box, the MicroK8s distribution of ingress-nginx installed as the MicroK8s addon ingress binds to ports 80+443 on the node’s IP address using a hostPort, as we can see here on line 20: This is fine for a single-node deployment, but now MicroK8s supports clustering we need to find a way of load-balancing our Ingress, as a multi-node cluster willContinue reading “Load-balancing Ingress with MetalLB on MicroK8s”
Exposing the Kubernetes Dashboard with an Ingress
With MicroK8s it’s easy to enable the Kubernetes Dashboard by running If you’re running MicroK8s on a local PC or VM, you can access the dashboard with kube-proxy as described in the docs, but if you want to expose it properly then the best way to do this is with an Ingress resource. Firstly, makeContinue reading “Exposing the Kubernetes Dashboard with an Ingress”
Building a hyperconverged Kubernetes cluster with MicroK8s and Ceph
This guide explains how to build a highly-available, hyperconverged Kubernetes cluster using MicroK8s, Ceph and MetalLB on commodity hardware or virtual machines. This could be useful for small production deployments, dev/test clusters, or a nerdy toy. Other guides are available – this one is written from a sysadmin point of view, focusing on stability andContinue reading “Building a hyperconverged Kubernetes cluster with MicroK8s and Ceph”
Fronting legacy services with Kubernetes
There are many benefits to Kubernetes but what’s not discussed so often is how to migrate your services from their legacy hosting to their new home in Kubernetes. Specifically, I’m looking at the case where you have a single server or a single public IP address and you want to run your services on thatContinue reading “Fronting legacy services with Kubernetes”
