Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Trying Finch and introduce containerd
The author uses a Mac and uses Docker Desktop or colima x Docker CLI to realize a Docker development environment. Dcoker Desktop uses an internal HyperKit (macOS hypervisor) to launch a Linux VM and run dockerd in it. Docker Desktop is based on Lima, and it generates Lima configuration files, and it is used to run Linux.

Docker on OpenBSD?
Sorry, I was misinformed. It seems MacOS still does use a tool called hyperkit to run a (presumably linux) VM as a backend for docker. I thought it was using something similar to jails.

New to ARM64 processors world
You might try using HyperKit as the hypervisor with Kubernetes. It uses Apple's own hypervisor. Minikube, or rather docker, supports it. I would go with minicube as you can start and stop it as needed with ease.

Anyone know how to pass a USB device from M1 mac to Ubuntu container?

A modern toolkit to start working with container images on macOS that meets your needs without requiring a Docker Daemon or even Docker Desktop
What’s the magic behind docker working on macOS?. The answer is virtualization accomplished by the moby/hyperkit hypervisor (AFAIK), a toolkit for embedding hypervisor capabilities in your application, which means that dockerd works in a VM virtualized by the hyperkit. Why I’m telling you this is once you decide to work with containerd on your macOS environment to discover capabilities and more adapt to it because we assume you use containerd in your Kubernetes environment as a default container runtime, you had to have the same virtualization technology under the hood to let containerd working on macOS. Also, you need to have some client tooling to interact with containerd by keeping simplicity and usability in mind.

Docker on Mac is based on Hyperkit which is a lightweight VM. https://github.com/moby/hyperkit Crostini is running in a full KVM instance. You challenged me about the Termina shell. Type it in and see if I'm right. No need to debate this anymore when you can verify for yourself.

Docker is not allowed for „big“ companies anymore
Docker Desktop doesn't use virtualbox behind the scenes. It uses hyperkit.

Trying Finch and introduce containerd
Direct use of containerd? containerd? turns out I didn't know anything about container technology. containerd was originally developed by Docker in 2015 as a daemon that provided basic container management capabilities under Docker. containerd's scope has gradually expanded and now seems to cover almost everything in the Docker Engine. For example, nerdctl is a CLI for containerd; the UX is almost identical to the Docker CLI, and Docker Compose is also supported (nerdctl compose).

Docker for Mac Without Docker Desktop
Nerdctl[1] (for containerd) works fine with docker-compose.yml for my purposes (which are not much). The only issue I encountered was with environment variable substitution not working the same as docker-compose, but I didn't look hard for a solution and edited my compose file
1. https://github.com/containerd/nerdctl mine came bundled with Rancher desktop, and 'nerdctl compose up' is all I've needed

K8 cluster and containerd Deployment
I haven't tried it personally but you might be able to export the tar from docker host with docker cli and then load it on containerd host using nerdctl - https://github.com/containerd/nerdctl

Podman, the open source Docker alternative ported to M1 (Apple Silicon) machines
It looks like the real nice thing here is having a formula for QEMU with the ARM patch applied: https://github.com/simnalamburt/qemu/tree/hvf
With this I believe you could also used [nerd](https://github.com/containerd/nerdctl) instead of podman but I haven't tested it yet.

Running Nomad for a Home Server
One area, where containerd didn't had a first class support was CLI. the default containerd CLI "ctr" has a very naive implementation. The reason for that I believe is, containerd as a system was never meant to be consumed by humans, and was designed to be consumed by higher layers e.g. orchestration systems like nomad or k8s. However, with the deprecation of dockershim in k8s, and users moving to containerd, a new docker compatible CLI came out:
https://github.com/AkihiroSuda/nerdctl
If you just have containerd running on your system (with no docker daemon running), you can just install nerdctl and add
alias docker="nerdctl"
to your ~/.bashrc file.
Then you can just run any docker commands the way you used to with docker, and it will run those commands against the containerd API giving you the same CLI experience that you used to have with docker.
