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.

is kubeadm sufficient?
Thanks for the feedback. I haven't tried BYOH yet, I am using vcluster, but I've been meaning to try flintlock and Liquid Metal.

Bare Metal Solutions
Have a look at Liquid Metal using microvms on baremetal and using flintlock. It's pretty frigging awesome. :)

Maestro: A Linux-compatible kernel in Rust
Isn't gVisor kind of this as well?
"gVisor is an application kernel for containers. It limits the host kernel surface accessible to the application while still giving the application access to all the features it expects. Unlike most kernels, gVisor does not assume or require a fixed set of physical resources; instead, it leverages existing host kernel functionality and runs as a normal process. In other words, gVisor implements Linux by way of Linux."

Faster Filesystem Access with Directfs
This sort of feels like seeing someone riding a bike and saying: why don’t they just get a car? The simple fact is that containers and VMs are quite different. Whether something uses VMX and friends or not is also a red herring, as gVisor also “rolls it own VMM” [1].

OS in Go? Why Not
There's two major production-ready Go-based operating system(-ish) projects:
- Google's gVisor[1] (a re-implementation of a significant subset of the Linux syscall ABI for isolation, also mentioned in the article)
- USBArmory's Tamago[2] (a single-threaded bare-metal Go runtime for SOCs)
Both of these are security-focused with a clear trade off: sacrifice some performance for memory safe and excellent readability (and auditability). I feel like that's the sweet spot for low-level Go - projects that need memory safety but would rather trade some performance for simplicity.

Tunwg: Expose your Go HTTP servers online with end to end TLS
It uses gVisor to create a TCP/IP stack in userspace, and starts a wireguard interface on it, which the HTTP server from http.Serve listens on. The library will print a URL after startup, where you can access your server. You can create multiple listeners in one binary.

How does go playground work?
The playground compiles the program with GOOS=linux, GOARCH=amd64 and runs the program with gVisor. Detailed documentation is available at the gVisor site.

Multi-tenancy in Kubernetes
You could use a container sandbox like gVisor, light virtual machines as containers (Kata containers, firecracker + containerd) or full virtual machines (virtlet as a CRI).
What are some alternatives?
talos - Talos Linux is a modern Linux distribution built for Kubernetes.
firecracker - Secure and fast microVMs for serverless computing.
ansible-role-k3s - Ansible role for deploying k3s cluster

kata-containers - Kata Containers is an open source project and community working to build a standard implementation of lightweight Virtual Machines (VMs) that feel and perform like containers, but provide the workload isolation and security advantages of VMs. https://katacontainers.io/
hetzner-k3s - A CLI tool to create and manage Kubernetes clusters in Hetzner Cloud using the lightweight distribution k3s by Rancher.
sysbox - An open-source, next-generation "runc" that empowers rootless containers to run workloads such as Systemd, Docker, Kubernetes, just like VMs.
