Many of the posts I read here are about Docker. Is anybody using Kubernetes to manage their self hosted stuff? For those who’ve tried it and went back to Docker, why?
I’m doing my 3rd rebuild of a K8s cluster after learning things that I’ve done wrong and wanted to start fresh, but when enhancing my Docker setup and deciding between K8s and Docker Swarm, I decided on K8s for the learning opportunities and how it could help me at work.
What’s your story?

Kubernetes is useful if you have gone full cattle over pets. And that is very uncommon in home setups. If you only own one or two small machines you cannot destroy infra easily in a “cattle” way, and the bloatware that comes with Kubernetes doesn’t help you neither.
In homelabs and home servers the pros of Kubernetes are not very useful: high availability, auto-scaling, gitops integrations, etc: Why would you need autoscaling and HA for a SFTP used only by you? Instead you write a docker-compose.yml and call it a day.
The one exception to this is if you’re using your homelab to learn kubernetes.
That was the only time I used K8s and k3s on my homelab.
And for anything that I do want to set up in a HA/cattle kind of way, I use Docker Swarm, as it feels like a more comfortable extension of docker compose.
Here’s a slightly different story: I run OpenBSD on 2 bare-metal machines in 2 different physical locations. I used k8s at work for a bit until I steered my career more towards programming. Having k8s knowledge handy doesn’t really help me so much now.
On OpenBSD there is no Kubernetes. Because I’ve got just two hosts, I’ve managed them with plain SSH and the default init system for 5+ years without any problems.
