Kubernetes

For my homelab I’m running an over-engineered one-node Kubernetes “cluster” using Cilium as the Container Network Interface (CNI). Up until recently I used MetalLB for LoadBalancer IP Address Management (LB-IPAM) and L2 announcements for Address Resolution Protocol (ARP) requests over the local network, but Cilium has now replaced this functionality.

This is going to be a bit of a follow-up on an earlier article on Cloudflare SSH tunneling where we configured SSH-tunneling through Cloudflare’s WARP-client. In this article we’ll configure Cloudflare’s cloudlared-tunnel and a Zero Trust Application to expose a browser rendered terminal to our server.

I use Argo CD to maintain my Homelab as I find it intuitive. The nice GUI also helps me to quickly inspect problems which might occur when I try something fancy. Another widely used alternative is Flux CD which solves the same problem of GitOps-ing your cluster, but I have little experience with it yet.
