The Prototype:

The final part:

That’s exactly what I’m doing, check out my GitHub repo I linked.

I’m friends with a DevOps engineer who has a similar repo, and he said it landed him his last two jobs.

Leave a Star if you like what you see

Did some reading, yea you’re right.

So many of the containers run in K8s are built with docker, but the containers themselves aren’t docker.

I think many people (like I used to 10min ago) think that docker = some-kind-of-container.

Best plain-English version:

Kubernetes is an orchestrator:

• Docker Engine and Podman are container engines.
• Kubernetes used to support Docker Engine via dockershim, but that support was removed in v1.24.
• Kubernetes now talks to runtimes like containerd or CRI-O.
• You can still build images with Docker and run them on Kubernetes, but Kubernetes is not “using Docker under the hood” in the old sense anymore.

Kubernettes is a orchestrator for containers.

As your article said, you don’t NEED to use docker.

But in many cases you do use docker, many of the containers I run are docker containers

Also K8s come with a LOT of other benefits almost all big systems run on K8s, you can view all your logs in once place, you can manage all your app versions and upgrades in one place, you can automate app upgrades and backups etc in one place. You can setup alerts for when services have issues or warnings etc.

K8s uses docker under the hood, once you have 3 nodes, you can plug out one of the nodes and the whole system will recover and all your services stay up.

I had a SSD fail on me and it brought down Immich and Nextcloud, then they were down for like a week while I did troubleshooting and ordered a new SSD.

Once my 3rd node is up, if a SSD fails I will just get a notification that my cluster is degraded, and I can investigate it while everything stays working.

It’s gross overkill for a homelab, but it’s fun to build and setup.

Thanks!! And still have a lot to do

One of the main reasons I started this is to be less dependent on Google, Microsoft etc.

Yes I know I use GitHub and Cloudflare, it’s a marathon not a sprint and perfection is the enemy of progress.

So if you came to the comments to scream at me for using GitHub/Cloudflare, please first see This

Old post of how my homelab started, and how things used to be: https://piefed.social/post/1002037

According to their own documentation: https://github.com/truenas/scale-build

The TrueNAS build system previously hosted here has been moved to an internal infrastructure.

This isn’t them stopping use of the build, it’s them making it proprietary. They are still using it, just not open-sourcing it.

It’s a fan controller. It’s a DIY way for me to power the fans and control their speed. It draws power from my NAS (the thing next to it)

Thanks will do

The T-Slot bolts are spring loaded so I can shift them to any height I like, for now they are spaced widely apart but once I can 3D print I’ll fit everything into 1/2U sizes

Thanks I’ve joined there as well
