dashboard VS k3s

Setting up and interacting with your first cluster can be overwhelming. Just like me, you might have come across the infamous kubernetes/dashboard, followed the installation instructions, and asked yourself: "What did I just do and why exactly does this work the way it works?" And after some tinkering with your cluster, you might have installed even more external tools that help you with some specific aspects of cluster management, providing you with either a CLI or a Web UI.

Loki needs Promtail

Kibana needs Elasticsearch

I'm not sure if this has good enough log viewing https://github.com/kubernetes/dashboard

The Kubernetes Dashboard could work for this use case.

yaml GITHUB_URL=https://github.com/kubernetes/dashboard/releases VERSION_KUBE_DASHBOARD=$(curl -w '%{url_effective}' -I -L -s -S ${GITHUB_URL}/latest -o /dev/null | sed -e 's|.*/||') sudo k3s kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/${VERSION_KUBE_DASHBOARD}/aio/deploy/recommended.yaml

paste the token created. Have fun! source1 source2

At the end of the guide, two web applications will be deployed: the sample ASP.NET Core app from Microsoft and Kubernetes dashboard. Both served on custom local domains with trusted TLS.

Here's an option developed by the Kubernetes folks, https://github.com/kubernetes/dashboard . There are several more options out there if you search for alternatives to this.

Kubernetes Dashboard GitHub tells:

sorry I misspoke this is the pattern I was thinking of - https://github.com/kubernetes/dashboard/blob/master/modules/web/Dockerfile

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.

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.

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.

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.

Kubernetes - k3s distribution

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.

You should be familiar with Kubernetes and have set up a Kubernetes cluster. I recommend k3s.
