Any love for Kubernetes here?
(lemmy.world)
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?
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
No shit. So you're saying I can hook up like three mini pcs and make a mega at home server!? I gotta look into this. Did you follow a guide or anything you think is good enough or is as easy as a Google?
My recommendation is to look into k3sup and Rancher. I had a lot of trouble trying to install rancher in a docker container and migrating to a cluster after, and k3sup makes it really easy to set up a k3s cluster without having to configure everything manually
You can accomplish the same task with docker swarm, but I figured it would be better to learn something that wasn't abandonware
I haven't dug into the storage side yet since I have a separate NAS, but it will probably be beneficial to set up something like Ceph, GlusterFS, or Longhorn if you don't have one
Oh I just realized this is for kubernates. Unraid is all dockers. Can a docker swarm also pool resources?
Yep, similar concept. Not sure how well unraid will handle the swarm behavior but I can imagine there's someone out there who has tried it before
