I'm using Swarm on a small cluster (3-5) machines. Is there any reliable Kubernetes alternative for that? Portainer as Swarm UI was buggy for me - a usable and stable UI would be nice, but I'm not sure if I should do the full Kubernetes dance :/ Easy to debug and lightweight would be also great. I didn't really found something good.

Almost all non kubernetes docker solution seem to be no longer maintained. But nomad is alive and has interesting concepts.

It's not like Kubernetes has a better UI. You could take a look at OpenShift. It's a Kubernetes based Open Source distro my Red Hat and it includes a quite nice UI, both for users and admins.

I'd be really interested to know more about your setup and processes if you're running Swarm in production? For example, how do you handle rolling updates?

  we are not a SaaS company, we just run some simple nodejs based services on swarm and my goal is to use swarm as a testing hub for docker - mostly the ci should push something there for the devs. So uptime does not matter, however swarm crashed badly a few times on me and at the moment everything important is well configured outside using your typical LTS linux distribution and I'm hesitant to move our basic services to it...basically 9-5 it has to work, I can just run apt-get update && reboot earlier or later - really not sure if I should move all the stuff into swarm / k8s - also because bus factor would be one and there is some experience with the old linux way. For everything that resembles a microservice/service -> Docker, everything else (ldap, mail) -> oldschool. So far so good. I'm looking at k3s or minikube with rancher as ui - maybe that's better, or we just ignore the hype and run docker-compose.yml files by hand but that's also pretty shitty.
