Colima k8s nix setup
What about the docker-cli? colima also ships with a docker-compatible cli to interact with containerd called nerdctl. We can execute the same docker cli commands like:

Nginx Unit – Universal web app server
Using nerdctl: https://github.com/containerd/nerdctl
I'd really disagree that compose files are somehow one-shot, or blindly modified. To the contrary, really, we have them checked in with the source code. Upon deployment to the cluster, the (running) services will be intelligently updated or replaced (in a rolling manner, causing zero downtime). LXC might be more elegant, but I have no idea what simple, file-based format I could use to let engineers describe the environment their app should run in without compose.
I need something that even junior devs can start up with a single command, that can be placed in the VCS along with the code, and that will not require deep Linux knowledge to get running. Open for suggestions here, really.

Jenkins Agents On Kubernetes
Now since Kubernetes works off of containerd I'll be taking a different approach on handling container builds by using nerdctl and the buildkit that comes bundled with it. I'll do this on the amd64 control plane node since it's beefier than my Raspberry Pi workers for handling builds and build related services. Go ahead and download and unpack the latest nerdctl release as of writing (make sure to check the release page in case there's a new one):

Going through a Kubernetes training with autogenerated captions and about half are coming up like this.
That's why nerdctl, their cli binary, is so well named.

Python + containerd? Who might be interested?
Well, it is indeed a good option. However, containerd is a good alternative that is growing even among developers. Please see: https://github.com/containerd/nerdctl

How to own your own Docker Registry address
Nerdctl/containerd has IPFS support :)

DockerHub replacement stratagy and options
nerdctl supports IPFS for both image pulling and pushing, including encrypted images and eStargz lazy pulling. For building, the current method is a locally hosted translator so that the traditional pulls can be converted to work over IPFS. They even have docs on running it on k8s node, though if my reading is correct this isn't exactly a cloud native approach (running systemd services on each node...).

Packer Workflows with Jenkins
Multipass I love Multipass for quick Ubuntu instances spun up for testing or as a playground. Wish I would have known and used of it sooner.

VMs on macOS using Apple's native Virtualization.Framework
If you just need Ubuntu then you can try "Multipass" from Canonical (https://multipass.run/). Works quite well on my M2 Air. I haven't tried using Linux GUI with it though as I need only terminal based VMs.

Simulate an Ubuntu-like VM inside macOS
Multipass is pretty clutch for trivial VMs on MacOs for sure. I use it for a bunch of ssh jump boxes running vpns to different sites. The macOS build does not support custom images (lest not without [some truly insane hacks](https://github.com/canonical/multipass/issues/1260#issuecomm...) , which doesn’t really matter for what I use it for but it is kind of a bummer. If you need something with a little more grunt but don’t want to go full blown with writing your own QEMU tooling or fussing with something like UTM or Parallels, [quickemu](https://github.com/quickemu-project/quickemu) is a really nice qemu wrapper with sane defaults that can expose a whole lot of power if you need it.

VirtualBox 7.0.10 download links have disappeared
I would be cautious or even distrustful of using anything from Oracle. VirtualBox components come under three different licenses - GPLv2, personal use & evaluation license, and an enterprise license. Their VirtualBox license FAQ [1] gives them enough leeway to change future licenses at will. If an exploit is discovered in your old VirtualBox and they've changed the license, you're out of luck.
We've moved our development to KVM and Virtual Machine Manager on Linux [3] and UTM on Mac [4]. There are other options to run your VM, such as Multipass [5] or VirtualBuddy [6].
On a digressive topic - it was fun migrating our legacy application server stack from Oracle Java (old & poorly considered decision) to OpenJDK, thanks to their license [2].

Lima: A nice way to run Linux VMs on Mac
How does it compare to https://multipass.run/?

Hands-on Kubernetes and maybe go for a certification
If you have a reasonably beefy computer, you can always try setting up Multipass and set up 2-3 nodes for a k8s cluster, it's how I'm doing my own certification training. I do have a k3s Raspberry Pi cluster, but with Pi prices being what they are still it'd almost be cheaper to do a cloud setup. ☹️

Colima: Container runtimes on macOS (and Linux) with minimal setup
Whenever I need a VM on my MacOS I reach out to Multipass[1].
It is a project by Canonical and has a decent amount of features to get the job done. However, it only supports Ubuntu VMs and has some rough edges.
What are some alternatives?
lima - Linux virtual machines, with a focus on running containers
podman-compose - a script to run docker-compose.yml using podman
colima - Container runtimes on macOS (and Linux) with minimal setup
kaniko - Build Container Images In Kubernetes
wsl-environments
podman - Podman: A tool for managing OCI containers and pods.
Moby - The Moby Project - a collaborative project for the container ecosystem to assemble container-based systems
docker-images - Official source of container configurations, images, and examples for Oracle products and projects
k3s - Lightweight Kubernetes
UTM - Virtual machines for iOS and macOS
