Do you run Docker in a VM or on the host node? I'm running a lot of LXC at home on Proxmox but sometimes it'd be nice to run Docker stuff easily as well.
Just create an LXC container to run your dockers, all you have to do is make sure you run the LXC as privileged and enable nesting.
There are security performance and capability concerns with that approach, apparmor on the first layer lxc probably being the most annoying.
If you want to isolate your docker sandbox from your main host, you should use a vm not a container.

I need a kubernetes cluster with high availability, load balancing and horizontal pod autoscaling, because that is something I want to learn. I don't care that it's just for wife's home-made dog collars webshop.
This is the way

I spend all day at work exploring the inside of the k8s sausage factory so I'm inured to the horrors and can fix basically anything that breaks. The way k8s handles ingress and service discovery makes it absolutely worth it to me. The fact that I can create an HTTPProxy and have external-dns automagically expose it via DNS is really nice. I never have to worry about port conflicts, and I can upgrade my shit whenever with no (or minimal) downtime, which is nice for smart home stuff. Most of what I run tends to be singleton statefulsets or single-leader deployments managed with leases, and I only do horizontal for minimal HA, not at all for perf. If something gives me more trouble running in HA than it does in singleton mode then it's being run as a singleton.
k8s is a complex system with priorities that diverge from what is ideal for usage at home, but it can be really nice. There are certain things that just get their own VM (Home Assistant is a big one) because they don't containerize/k8serize well though.

A mini PC is a good middle ground. Mostly for the video transcode and machine learning power.
Yeah, a mini PC... or if you already have one, why not 5 mini PCs?
That's what Iam aiming for at the next hardware update. I don't have the space for a server rack and a SFF desktop would also not fit into my home, so a miniPC it'll be. I cannot wait to move to x86.

As a developer and not a sysadmin, I refuse to learn anything more than docker. It's good enough for me π€
Edit: on a more serious note, proxmox with docker containers has been more than enough for me

I've been enjoying Jeff Geerling's ongoing experiments with his 10" Raspberry Pi mini rack.
It doesn't work for me since all of my network equipment is 19" and there's no point in having two racks but having a 10" standard is still a great idea!
Off-topic but can you tell me why your name is red? I use Voyager and your name is red, it should mean something, right?

Ha ha
Under-complicated -> over-complicated -> under-complicated.
There's a 'just right' that I think you skipped through.
Ain't nobody got time for that
Random mixed parts -> 4u unraid server with switch -> random fedora Optiplex that never fails unlike 4u server

I've discovered that there are a lot of medium-tier software engineers who immediately will go straight to horizontal scaling (i.e: just throw hardware at it), and I've seen instances where very highly skilled engineers just write their code better, set things up on a bare metal server, cache things, etc. and manage with just a single badass server
Right? I just spin up another process on my home server. No need to get more hardware involved for something that's inherently a software problem.
Even just the choice of programming language makes a big difference. Running a JVM language or NodeJS, Python, Ruby etc., you can be bottlenecked by a Pi. Meanwhile, Rust or C/C++ will use barely a fraction of those resources.
Yup, a pi is enough for me.
Well... 5 Pis and an ancient NUC running proxmox are enough for me. And a DS920+... and an old laptop running docker are enough for me.
With Linux any old computer from yesteryear can become a quick server. That's what I do, just make sure you got backups.
My home server is literally made from garbage left over from other PCs. The motherboard is currently some piece of junk from a prefab PC with a custom power socket, so I got to make my own adapter from scratch.
Yup! When I built a gaming comphter last year my old desktop became my first dive into linux. Probably overkill, but ive been having a blast with it.
Nice!
Floor PCs FTW

Switched from a raspberry pi 3 to a second hand x86 thin client (lenovo thinkcentre m920q) because raspberry pi 4 were not available at the time. Made me learn proxmox and a bunch of other cool stuff my raspi couldn't handle.
I'm rooting for ARM / RISC-V to become more popular in desktop computing / servers though.
Is there RISC-V hardware already? I thought the specification was still under development.

Waiting for proxmox-arm becoming a thing (I know there's some community versions trying it but I'm not sure how reliable they are)
The hardware virtualisation available for arm just isnβt there yet
Apple Silicon Macs do a great job with virtualization. Outside of them there's just no nice high end hardware that's well suited for something like proxmox. It's either low end SBC, or the hyper proprietary ARM servers that I don't think we can even buy.
Those are heavily customised, weβre talking raspberry piβs here

I've always liked riscv. Just the idea of literally everything on the device being open source is a fun idea. Manuals to everything.

I need
It's just fun to play with, there is no "need".
Yeah, I enjoyed my time with k3s setup at home as well, but right now I don't really want nor need that π
rPi with k3s installed
How does that compare to microk8s? I have been using that for a while and like the plugins.
k3s
kbnts?
That's not a typo: https://k3s.io/
It's basically a Kubernetes cluster, which you can run locally on your PC. Really useful for playing around with Kubernetes before you move to a 'proper' environment.
That's neat, and also gives me another reason to hate numeronyms π
