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.

How to connect to a docker container service when it's running on a mac?
This is due to the way Windows and OSX implement docker. They both use a VM running Linux; Windows uses Hyper-V and OSX uses Bhyve. (https://github.com/machyve/xhyve)
-
Asymptotic Notation !
Nowadays, docker uses runc, that is OCI compliant. Docker on macOS uses Hypervisor.framework through xhyve, and is completely macOS native. No VM is used (even under the hood) when running docker on macOS, it's native.
- Does xhyve on MacOS (Monterey) supports the passthru of the GPU ?

Favourite Hypervisor for a macOS Host?
I was happiest with xhyve https://github.com/machyve/xhyve
Serial console in terminal was nice (for me!), network configuration was trash (I think I was able to set the subnet by fiddling around with system plists? and it would revert from time to time), and I didn't have to deal with Virtualbox. I've been away from macs for a while, I don't know if xhyve works on the M1, but it might. I ran a FreeBSD vm so I could run my server code on my laptop in an environment that was like production but slower.

[Desktop] Mac mini – Apple M1 Chip 8-core CPU, 8-core GPU – 8GB Memory – 256GB SSD - $569.99 ($669.99-$100)
Docker for Mac actually spins up TinyCoreLinux VMs using xhyve that your docker containers run on top of. This is because containers borrow the host kernel, so you can't natively run Linux containers on Mac. Xhyve spawns VMs so a Linux kernel will be present.

There's also been a port of FreeBSD's bhyve to macOS for years: https://github.com/machyve/xhyve (which, in turn, is [or at one point was] used by Docker to virtualize Linux)

What Is Your Hypervisor
I've used xyhve on my Mac to have a FreeBSD VM running a copy of https://www.freshports.org/, including a copy of the database, which runs about 200GB. For dev work, it was fine. I used it when I didn't have [great] internet connectivity, for example, when on the train/plane. When upgrading packages or just doing dev work, it was great.

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.

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].
