Docker Compose is simple: You have a Compose file that just needs Docker (or Podman).

With k8s you write a bunch of manifests that are 70% repetitive boilerplate. But actually, there is something you need that cannot be achieved with pure manifest, so you reach for Kustomize. But Kustomize actually doesn't do what you want, so you need to convert the entire thing to Helm.

You also still need to spin up your k8s cluster, which itself consists of half a dozen pods just so you have something where you can run your service. Oh, you wanted your service to be accessible from outside the cluster? Well, you need to install an ingress controller in your cluster. Oh BTW, the nginx ingress controller is now deprecated, so you have to choose from a handful of alternatives, all of which have certain advantages and disadvantages, and none of which are ideal for all situations. Have fun choosing.

Literally got it in one, here. I’m not knocking Kubernetes, mind, and I don’t think anyone here is, not even the project author. Rather, we’re saying that the excess of K8s can sometimes get in the way of simpler deployments. Even streamlined Kubernetes (microk8s, k3s, etc) still ultimately bring all of Kubernetes to the table, and that invites complexity when the goal is simplicity.

That’s not bad, but I want to spend more time trying new things or enjoying the results of my efforts than maintaining the underlying substrates. For that purpose, K8s is consistently too complicated for my own ends - and Uncloud looks to do exactly what I want.

And if you want to use more than one machine then you run `docker swarm init`, and you can keep using the Compose file you already have, almost unchanged.

It's not a K8s replacement, but I'm guessing for some people it would be enough and less effort than a full migration to Kubernetes (e.g. hobby projects).

This is some serious rose colored glasses happening here.

If you have a service with a simple compose file, you can have a simple k8s manifest to do the same thing. Plenty of tools convert right between the two (incl kompose, which k8s literally hands you: https://kubernetes.io/docs/tasks/configure-pod-container/tra...)

Frankly, you're messing up by including kustomize or helm at all in 80% of cases. Just write the (agreed on tedious boilerplate - the manifest format is not my cup of tea) yaml and be done with the problem.

And no - you don't need an ingress. Just spin up a nodeport service, and you have the literal identical experience to exposing ports with compose - it's just a port on the machines running the cluster (any of them - magic!).

You don't need to touch an ingress until you actually want external traffic using a specific hostname (and optionally tls), which is... the same as compose. And frankly - at that point you probably SHOULD be thinking about the actual tooling you're using to expose that, in the same way you would if you ran it manually in compose. And sure - arguably you could move to gateways now, but in no way is the ingress api deprecated. They very clearly state...

Plenty of valid complaints for K8s (yaml config boilerplate being a solid pick) but most of the rest of your comment is basically just FUD. The complexity scale for K8s CAN get a lot higher than docker. Some organizations convince themselves it should and make it very complex (debatably for sane reasons). For personal needs... Just run k3s (or minikube, or microk8s, or k3ds, or etc...) and write some yaml. It's at exactly the same complexity as docker compose, with a slightly more verbose syntax.

Honestly, it's not even as complex as configuring VMs in vsphere or citrix.

Might need to redefine the port range from 30000-32767. Actually, if you want to avoid the ingress abstraction and maybe want to run a regular web server container of your choice to act as it (maybe you just prefer a config file, maybe that's what your legacy software is built around, maybe you need/prefer Apache2, go figure), you'd probably want to be able to run it on 80 and 443. Or 3000 or 8080 for some other software, out of convenience and simplicity.

Depending on what kind of K8s distro you use, thankfully not insanely hard to change though: https://docs.k3s.io/cli/server#networking But again, that's kind of going against the grain.

If you just want to do development, honestly it's probably better to just use kubectl port-forward (ex - map 3000, or 8080, on your machine to any service/pod you'd like).

As for grabbing 443 or 80, most distros support specifying the port in the service spec directly, and I don't think it needs to be in the range of the reserved nodeports (I've done this on k3s, worked fine last I checked, which is admittedly a few years ago now).

As you grow to more than a small number of exposed services, I think an ingress generally does make sense, just because you want to be able to give things persistent names. But you can run a LONG way on just nodeports.

And even after going with an ingress - the tooling here is pretty straight forward. MetalLB (load balancer) and nginx (ingress, reverse proxy) don't take a ton of time or configuration.

As someone who was around when something like a LAMP stack wasn't "legacy", I think it's genuinely less complicated to setup than those old configurations. Especially because once you get it right in the yaml once, recreating it is very, very easy.
