Kubernetes is great for single nodes! It definitely is more advanced than docker compose, but it’s actually not hard at all if you read through the documentation. It definitely makes running containers easier in the long run.
Here is my git repo for my big Kubernetes cluster at home: https://codeberg.org/jlh/h5b/src/branch/main/argo/custom_applications
It started out as just a NFS server and a Kubernetes server running on Proxmox in 2021.
It’s not going to make a meaningful difference in your threat model and it will cause a lot of hassle for extra configuration and broken docker images, so I wouldn’t bother.
There is some nice tooling for transparent user name spaces coming down the pipeline in Kubernetes which will be a nice 0-effort security upgrade, but if you don’t have the tooling, I would say it’s not worth it.

SSDs are getting crazy cheap.
If you need 10tb of storage, you could get 2x used 10tb hdds in raid 1 for $200, but 6x used 2tb nvme in raid 5 is only $600 and 100x faster. Both take up the same amount of space.
SMR is designed for enterprise raid that is SMR-aware.
I’m not aware of any open-source zoned storage raid but I think Ceph is planning to add support next month.
Hetzner Storage box is $20/month for 10tb.
They literally campaigned on a slogan saying that doubling the prison time would cut crime in half. Insanity.
Better source from Vox:
The memo in question:
Easy fix, just have the AI summarize what happened in the last week for you so you don’t confuse it with multiple languages. Now you don’t have to talk and the other person doesn’t have to listen!
I expected an option that replaces Aunt Janet with an AI voice that summarizes each sentence. Gotta justify all this money on AI somehow.
~, doing things like configuring browsers or dotfiles. As opposed to NixOS modules which configure system-level daemons.Ah cool, I’ll check it out.
The home manager documentation bothers me a lot
Probably not that hard to build a simple flask frontend around it.
Automatically processing files in an S3/WebDAV directory would also be useful.

There is also a k3s option for Nixos, which removes the security and side-affect risks of running a random bash script installer.
Very true. Each brick you lay upgrades your setup and your skillset. There are very few mistakes in Kubernetes as long as you make sure your state is backed up.
For question 1: You can have multiple resource objects in a single file, each resource object just needs to be separated by . The small resource definitions help keep things organized when you’re working with dozens of precisely configured services. It’s a lot more readable than the other solutions out there.
For question 2, unfortunately Docker Compose is much more common than Kubernetes. There are definitely some apps that provide kubernetes documentation, especially Kubernetes operators and enterprise stuff, but Docker-Compose definitely has bigger market share for self-hosted apps. You’ll have to get experienced with turning a docker compose example into deployment+service+pvc.
Kubernetes does take a lot of the headaches out of managing self-hosted clusters though. The self-healing, smart networking, and batteries-included operators for reverse-proxy/database/ACME all save so much hassle and maintenance. Definitely Install ingress-nginx, cert-manager, ArgoCD, and CNPG (in order of difficulty).
Try to write yaml resources yourself instead of fiddling with Helm values.yaml. Usually the developer experience is MUCH nicer.
Feel free to take inspiration/copy from my 500+ container cluster: https://codeberg.org/jlh/h5b/src/branch/main/argo
In my repo, custom_applications are directories with hand-written/copy-pasted yaml files auto-synced via ArgoCD Operator, while external_applications are helm installations, managed via ArgoCD Operator Applications.
helm charts are awful, i didn’t really like cdk8s either tbh. I think the future “package format” might be operators or Crossplane Composite Resources
Excuse you, I don’t have a problem.
There’s much better algorithmic and datatype optimizations to be made than to design your app around saving 3 bytes that most runtimes probably represent as a long long anyways
I believe only the controller needs cooling, not the dies.
