The amount of services running is not an indication of how lightweight the underlying tech is. K3S is for orchestration across nodes, and by design you can't run services on the master for security reasons unless you manually change it.
Are you trying to say that 10 services and 2 nodes would be less on Nomad?
Re: K3s – Lightweight Kubernetes
#33Earlier quoted context omitted.
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 ne…
So all of those can be used to host a highly available multi physical node cluster?
k3s and microk8s definitely support multiple node setup. I'm not sure about kind or minikube (Maybe? You'd have to look into the docs). How ready they are and how well they'll scale out will depend a lot on how the controllers are setup.
k3s, at least, supports multiple controller nodes on setup.
Where things really get squirrelly, at least with k3s, is storage and ingresses. k3s supports both but in a super robust fashion.

#34Interestingly, 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. [0] https://www.suse.com/news/suse-completes-rancher-acquisition...
If you want to easily try it out, we baked it into Rancher Desktop [1]. RD let's you run Kubernetes (via k3s) and containers on your desktop. You pick the k8s version.

Disclosure, I work for SUSE and started Rancher Desktop.

Nomad also doesn't have nearly half of the features that Kubernetes does. Need service discovery? Set up a Consul cluster. Need secret management? Install vault. Need vault enterprise? Install a separate Consul cluster! This was a few years ago, maybe it's changed? I dunno.
Anyway, lightweight here means that whole bunch of external dependencies have been ripped out. E.g. AWS/GCP/Azure and I believe other things too.

You can run k3s with a single node. In that case it uses sqlite instead of etcd which is great for a smaller resource footprint. If you're comparing k8s distros, you'll be hard pressed to find a setup that uses fewer system resources.

#37We have been using K3S in production now for 2 years. And it's working like a charm.

Nomad is an alternative to k8s, but it is not really a "lightweight k8s". Nomad and k8s are way to different to call them versions of eachother.
And the whole license thing. Nothing changed for end users.

#39forget about it if you want to run it on an IPv6-only VPS, it's not ready yet
K3s absolutely supports ipv6-only

Does Nomad expose an API that you can extend with controllers running inside the cluster? Because Kubernetes without operators is not Kubernetes.
