Running kubernetes in your homelab is a fantastic way to learn, explore, express yourself, and run services that you use.

Running kubernetes in your homelab is complex, time consuming, there are almost no docs to help you (homelab focused docs for things you want to install), and nothing is copy paste. You have to make everything happen yourself.

No it’s not. It’s much different than running docker, compose, swarm. It’s meant for scale, it’s complex, it’s made for enterprise, not your local development or your homelab. It can do these things, it can do them quite well, but it’s not the target audience.

Yes

Ok we should probably dive deeper into this, but good chance if you are here and have made it this far you it would probably be a fine choice. The choice is quite time and skill dependant.

First thing up, if you like copy pasting thing into your homelab, changing a few config options, but mostly running it as the docs instructed, kubernetes is not for you. The homelab/self hosting space is heavily reliant on docker compose, 90% of the things you want to run will likely have a docker command, and likely a docker compose example that you can copy paste and get running right away. Maybe 5% of projects have something for kubernetes, you Will have to do it yourself.

I’m setting up longhorn in my homelab, and I ran into an issue where I initially setup some pvcs under longhorn, and later realized that to get longhorn to snapshot and backup I needed to hand edit volumes after the fact or change storage class. I’m all in on gitops so option 1 was not an option. So changing storageclass it is.

Now the issue is that you CANNOT mutate storageclass on a provisioned pvc, it is an immutable attribute.

This migration job will create a new pvc with the new storageclass and move the data from the old pvc to the new pvc.

I connected my home network to have 4G bakcup with Google Fi and Netgear LM1200. Goodle Fi offers free data-only sim cards that you can order from their service. It takes a couple of days, and a new sim arrives in the mail free of charge. It does pull data from your account, so if you are not on an unlimited plan be careful of how much you let go through the sim.

I’ve owned this for a few years now, but it’s been disconnected for a good six months or so. I’m not s[e what happened, but it stopped recognizing the old sim card. no need to point out the coffee stains at the end, its definitely not related

Activating the sim asked for a confirmation code shipped with the sim card, then brought me to this page.
