piku VS awesome-home-kubernetes

I like it. I wrote Piku (https://github.com/piku/piku) with much the same interest in fixing some of my pains, so I get where you're coming from with this. Will drop it into one of my current projects to build ESP32 binaries :)

I never had any serious issue with SD cards since the Pi 2B (and I've kept Pis running for years).

Anyway, for those wanting to deploy more generic apps, that is why I initially wrote https://github.com/piku/piku - you still have to flash the OS (and rpi-imager does that with sane defaults these days), but once you're done you have Heroku-like deployments for any language runtime you install on the Pi.

I also have https://github.com/rcarmo/ground-init, a cloud-init like shim that simplifies setting up machines (I'm a big fan of cloud-init, but since Raspbian doesn't support it and Ubuntu on ARM requires some fiddling to make it work I decided it wasn't too hard to roll my own).

(I probably should look into glueing that into rpi-imager, but there is are only so many hours in the day...)

I automated that away a long time ago: https://github.com/piku/piku/blob/master/piku.py#L814

So, stupid question: why couldn't I just use the 'baremetal' OS provided by Hetzner, install Postgres, Redis & node, create a separate db for each app, and run each app with https://github.com/piku/piku on a different port? For backups, I'll setup crontab to dump dbs locally and to S3.

piku?

Also check out the awesome kubernetes@home repo where many homelabbers share their configs.

Sorry I'm not familiar with this. Are you referring to this?

https://github.com/k8s-at-home/awesome-home-kubernetes https://github.com/k8s-at-home/template-cluster-k3s

To see it in action be sure to check out my repository or the many others here.

Make it usable and link to the best place with k3s in action: https://github.com/k8s-at-home/awesome-home-kubernetes

Nice but I suggest going to https://github.com/k8s-at-home/awesome-home-kubernetes and learn from the best at this topic ;)

Check out Flux V2. It syncs a git repo with your cluster, allowing you to define your infrastructure as code. It will keep your cluster synced with your repo and detect changes. A number of example repos are Here and onedr0p did a example repo here There's many options for structuring folder, I'd recommend you have a look at a few repos and pick one you like. The linked template is a good start, as it helps avoid dependency hell with a crd folder that starts before the YAML that needs the crd defined. Many people on the awesome list also run ansible for full infrastructure as code. I spent a lot of time perfecting my setup to go from blank Ubuntu VM to my cluster with a few keystrokes. Running it in git also helps you be able to use things like renovate bot to keep versions up to date. As for namespaces, everyone had their own method, but about using kube-system. Also, keep a eye out for services that refuse to have their name space changed.
