In the Gateway API SIG’s own words, If you’re familiar with the older Ingress API, you can think of the Gateway API as analogous to a more-expressive next-generation version of that API.

In this article we’ll explore how to use Traefik in Kubernetes combined with Cert-manager as an ACME (Automatic Certificate Management Environment) client to issue certificates through Let’s Encrypt.

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.

In a recent article I wanted one of the images to change dynamically with the theme. I didn’t find any support for this in the Blowfish Hugo theme I’m using, so I had to get creative. I also wanted to reuse an earlier shortcode I experimented with for automatically resizing images.

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.

Being able to log into your servers from everywhere with an internet connection is convenient as you never know when something may decide to break. However, exposing your ssh-connection to the open web can pose security risks if not done correctly. There’s a plethora of solutions to help with this, e.g. Tailscale, OpenVPN, ngrok, or similar VPN providers. In this article we’ll focus on Cloudflare’s cloudflared1 to securely tunnel ssh connections to a remote server.
