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.

Gokrazy – Go Appliances
Another project that aims to deliver this is Linuxkit (https://github.com/linuxkit/linuxkit). All the components they ship are written in memory safe languages (usually Go) and run as containers under containerd. You can build a custom image very easily, fully defined as a YAML file.

An overview of single-purpose Linux distributions
docker-the-company maintained https://github.com/linuxkit/linuxkit when I worked there. I have no idea who maintains it now, but it looks like it is still active (presumably still docker-the-company, since their adopters list [1] lists docker desktop).

Unpopular opinion: I was promised lightweight containers but I got yet another VM
Behind the scenes Docker Desktop for Mac spawns a linuxkit VM with a bit of extra stuff like NFS to enable mounting Mac paths into containers. In the Docker Desktop settings you'll find the current resource assignment for that VM. That is pretty much reserved for docker so that it does not have to compete with MacOS processes for available resources.

What happened to the nice Ansible cloud (provisioning) listing?

Ask HN: How are you using unikernels?
The definition of what a unikernel is needs to be narrowed down, a lot of these projects in the space (not all the ones listed above) have material differences that are not clear:
- some run only one language
- some require recompilation
- some essentially swap out libraries, others do something closer to dropping your already mostly static binary in a minimal disk image
- some build pid1 processes, others VMs images
Anyway, here are some additional entries in the space:
- https://ssrg-vt.github.io/hermitux/
- https://github.com/linuxkit/linuxkit (more embedded/minimal VM than unikernel)
- https://nabla-containers.github.io/ (runs on Solo5)
I am going through using Linuxkit to build AMIs for cloud providers now. I wouldn’t necessarily class linuxkit as a universal project because it doesn’t have the hallmark blurring of user and kernel space or kernel-as-a-library but you can customize the kernel so it’s an adjacent idea, and I think it’s the one most likely to be in actual use at non-hyperscalers.

Unikraft: Fast, Specialized Unikernels the Easy Way
I believe there is growing interest in providing leaner, "trimmed" runtimes for services deployed to the cloud. Today, this is seen largely by specializing the Linux kernel for, for example, container services[0] or in general[1], as much as that is possible (the paper above covers this problem in greater detail). But, Unikernels in themselves are not yet widely adopted. This is the space Unikraft is aiming to enter, providing the ultimate level of specialization for a target application.
It's clear that bigger players, such as Red Hat[2] are interested in the topic of unikernels, and that cloud providers are preparing for this future too [3].

Blog: KWOK: Kubernetes WithOut Kubelet
Docker Desktop runs dockerd in a Linux VM with Apple's hypervisor framework. You can also run containers in a Linux VM with Parallels or VMware Fusion hypervisors. But you can't run VMs inside those VMs as it stands today. This works fine on Intel Macs which means you can't experiment and use KVM - one of the killer features of Linux and things like https://kubevirt.io/

Docker + portainer vs k8. EILI5
Proxmox VE can run VMs and LXC containers (see my comment below on LXC). Kubernetes can run OCI containers, but there's also KubeVirt for running VMs.

Live Switching Pods to another Node on Resource Limits
Another option would be something like KubeVirt but that is a different use case where you are actually running a VM in a container for hard-to-containerize workloads.
What are some alternatives?
nanos - A kernel designed to run one and only one application in a virtualized environment
harvester - Open source hyperconverged infrastructure (HCI) software
unikraft - A next-generation cloud native kernel designed to unlock best-in-class performance, security primitives and efficiency savings.

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/
