    K3s is another compact Kubernetes distribution. Developed by SUSE, it's packaged as a single binary that comes in at less than 70MB. Despite this tiny footprint, K3s is certified as compatible with upstream Kubernetes, is ready for production use, and supports high availability.

    Opinionated meaning it picks, install, patches your CNI/Ingress/Load Balancer/DNS Server/Metrics Server/Monitoring Setup.

    k3s is probably most well known as it ships with bunch of preinstall software: https://github.com/k3s-io/k3s so you can just start throwing yaml files at cluster and handling workloads. It's what I use for my homelab.

    Paid things I've heard of include OpenStack and SideroLabs. Haven't used personally by SRE coworkers say good things about them.

  • Linux fu: getting started with systemd

    For self-hosting I've found https://k3s.io to be really good from the SUSE people. Works on basically any Linux distro and makes self-hosting k8s not miserable.
  • Nix is a better Docker image builder than Docker's image builder
    21 projects | news.ycombinator.com | 15 Mar 2024
    Yes it’s going to depend on which k8s distribution you’re using. We have work in-progress for k3s to natively support nix-snapshotter: https://github.com/k3s-io/k3s/pull/9319

    For other distributions, nix-snapshotter works with official containerd releases so it’s just a matter of toml configuration and a systemd unit for nix-snapshotter.

    We run Kubernetes outside of NixOS, but yes the NixOS modules provided by the nix-snapshotter certainly make it simple.

    K3S: is a lightweight distribution of Kubernetes that is designed for resource-constrained environments. It is an excellent option for running Kubernetes on a virtual machine or cloud server.

  • K3s Traefik Ingress - configured for your homelab!
    3 projects | dev.to | 15 Dec 2023
    I recently purchased a used Lenovo M900 Think Centre (i7 with 32GB RAM) from eBay to expand my mini-homelab, which was just a single Synology DS218+ plugged into my ISP's router (yuck!). Since I've been spending a big chunk of time at work playing around with Kubernetes, I figured that I'd put my skills to the test and run a k3s node on the new server. While I was familiar with k3s before starting this project, I'd never actually run it before, opting for tools like kind (and minikube before that) to run small test clusters for my local development work.

  • Building a no-code Helm UI with Windmill - Part 1
    3 projects | dev.to | 6 Dec 2023
    I’ve created a local cluster with K3S and installing Windmill could not be simpler with just one chart to configure, which already has sane defaults to get started. For this demo we will also configure workers to passthrough environment variables to our scripts so that they have access to the Kubernetes API server for later.

    actually that is not really true - i strongly urge you to try out http://k3s.io/ or https://k0sproject.io/

    these are full-fledged, certified k8s distributions that run on raspberry pi as well as all the way in production.
