kubeadm VS k3s

It works on top of KubeADM, you can also implement specific configuration about it.

https://github.com/kubernetes/kubeadm/blob/main/docs/ha-considerations.md was a huge help in getting it up and running.

Kubeadm is a more barebones tool, focusing on cluster node setup and Kubernetes component installation. It’s a command line tool that facilitates the various setup operations, but configuration needs to be done manually and per node.

For HA I opted for keepalived + haproxy and it has been working quite well so far (followed the guide from https://github.com/kubernetes/kubeadm/blob/main/docs/ha-considerations.md)

- set up with a Load Balancer (I'm using haproxy)

This is a useful guide on how to set them up (note: the version of HAProxy they specify is no longer being maintained, but you can upgrade it to a later version): Kubeadm - HA Considerations

Hi, last few days I'm solving the same thing. So I found some helpful github issue https://github.com/kubernetes/kubeadm/issues/581 maybe it helps.

Kubeadm is a cluster provisioning tool implementing the best-practices for creating Kubernetes clusters (following Kubernetes The Hard Way steps). Kubeadm performs the actions necessary to get a minimum viable and secure cluster. It follows Kubernetes operator architectural approach for cluster creation and management. What is also important, Kubeadm is an official Kubernetes SIG Lifecycle project - this is important because official Kubernetes SIG projects usually tent to have better community support and be more mature than their non-official counterparts.

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.

K3s' go.mod[0] is insane.
