Why use this over kubernetes, if it's the same but less memory why not only use k3s ans drop k8s

There's no real "over kubernetes". K3s is a kubernetes implementation.

You have to think of k8s as more of a specification of what can be done with multiple implementations. k3s, kind, microk8s, minikube are all implementations of kubernetes that you might want to try out.

k8s is much like the original IBM pc or a linux distribution. There are a bunch of interchangeable parts that you may land on depending on your needs.

Why use this over something else? I've found k3s to be really simple to setup and upgrade, which is why I use it for my home lab.

Because this makes certain assumptions and certain decisions about the Kubernetes Environment you want to be running.

See here: https://docs.k3s.io/

It's fully compliant but opinionated towards the smaller side.

Can this tool help to simplify self hosting implems? K3s was recommended to me to replace my personal pile of systemd units starting docker compose configs and manual reverse proxy configs. Im am completely oblivious to how k8s works.

K3s/k8s may help with that, but it's going to be a learning curve. I personally moved onto k8s for a similar reason, but it was a learning curve

Check out https://kamal-deploy.org, it just hit 1.0 and 37signals moved their whole Kubernetes stack to it. I was playing around with it recently for side projects and I think it's a nice fit for simpler products like that.

People often say kubernetes is complex, or overkill for tasks.

But let's say you have many computers and want to put them to work. Suddenly, kubernetes becomes the simplest of all options.

"Lightweight Kubernetes" and then a graph involving 2 different nodes with 10+ services running on them.

Nomad seems to be a truly "lightweight Kubernetes" and for the small amount of time I've been using it, it seems to do it's job really well and it's easy to understand all the moving pieces without spending countless of hours reading docs and source code.

Although, it's hard to recommend Nomad for future uses as it sadly stopped being FOSS :/

Interestingly, SUSE now owns Rancher [0], so k3s has been backed by a large company for some time now. I've never tried k3s, but I have always thought it's probably the most loved-by-its-users version of Kubernetes.
