Direct Server Return (DSR) is a networking technique that allows a backend server to learn the original request’s source IP address and respond directly, even behind a load balancer.

The Border Gateway Protocol (BGP) is used for routing information between so-called autonomous systems (AS).

Custom OIDC claims allow more granular control as we can give each client application its own scope with custom claims.

Authelia is an open-source authentication and authorisation solution, fulfilling an identity and access management (IAM) role, providing multi-factor authentication (MFA) and single sign-on (SSO) for applications via a web portal.

Self-hosting multiple applications often means having to deal with disparate user accounts unless you can integrate them with a common third party.

Kubernetes RBAC configuration can seem like a daunting task at first.

Traditionally, an ideal Kubernetes workload should be stateless, meaning it should be able to run anywhere and scale freely, though this also severely limits which kinds of applications we can run, i.e. stateful applications.

SREDay London 2024 together with the day-0 TalosCon1 just finished, and I’m happy I got to attend!

Talos is an immutable operating system designed to only run Kubernetes.

If you plan to run stateful applications in your Kubernetes cluster, you quickly run into the question of where to store this state.

Taking advantage of hardware acceleration can drastically reduce both CPU and power usage when playing video, enabling seemingly innocuous chips — like the Intel N100, to render multiple 4K video streams.

In this article we’ll take a look at how to proxy external services through the Kubernetes Gateway API.

In my previous article we took a look at how to bootstrap K3s with Cilium starting from a fresh Debian 12 network installation.

Getting started with Kubernetes might seem like a daunting task at first, but getting a basic ephemeral cluster up and running with tools like minikube, kind, or k3d is quite straightforward if you follow their documentation.

With the LLM era upon us, I’ve been wanting to play around with some of the open source, self-hosted toys available.

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).

In a recent article I wanted one of the images to change dynamically with the theme.

My first motorcycle was a Moto Guzzi V65 Custom from 1986 which I constantly tinker with.

Hi, and welcome!

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.

I use Argo CD to maintain my Homelab as I find it intuitive.

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.
