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?
Love is a strong word, but kubernetes is definitely interesting. I’m finishing up a migration of my homelab from a docker host running in a VM managed with Portainer to one smaller VM and three refurbished lenovo mini PCs running Rancher. It hasn’t been an easy road, but I chose to go with Rancher and k3s since it seemed to handle my usecase better than Portainer and Docker Swarm could. I can’t pass up those cheap mini PCs
Does rancher connect the pcs together? I have like 3 mini pcs sitting around, and I’ve always wanted to kinda combine them somehow
Like being able to combine cpu power or something. Idk if this is possible without getting a mobo with multiple cpu slots, but if it is. I’d love to learn!
Yeah, Kubernetes is designed to run in a cluster so you can pool processing power and memory from multiple devices. I banged my head against the wall for hours trying to figure out how to set up a cluster by hand, but then discovered if you install Rancher in a regular docker container it can handle all that for you
