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.

Speed boost achievement unlocked on Docker Desktop 4.6 for Mac
Both Kata Containers and UTM support virtio-fs, so this is not strictly true. The former can be used as a stand-in replacement for the runtime used by docker desktop[1]. With the latter, one could use a UTM-backed guest as a docker runtime in macOS[2] or run docker directly on the guest[3].

Kubernetes Security Checklist 2021
For services with increased security requirements, it is recommended to use a low-level run-time with a high degree of isolation (gVisior, Kata-runtime)

Kata Containers on GKE?
On the official Kata repo, I found a tutorial only for manually deployed Kubernetes on GCE.

Monitoring Elixir Apps on Fly.io with Prometheus and PromEx
This is new and may not be used much, but it is possible to use part of Kata with part of Firecracker. https://github.com/kata-containers/documentation/wiki/Initia...

Docker Without Docker
If it's using firecracker, it's probably using KVM virtualization while ensuring that the memory the VM consumes is not pinned... that is, that the VM can be swapped out of memory. For reference, firecracker was created by AWS to run and secure AWS Lambda. The hypervisor is written in rust and uses seccomp to eliminate unnecessary system calls. They open sourced it a few years back.
What you gain is a stronger security boundary. Just FYI, since 2019, you can also do this in Kubernetes using Kata containers which will happily shim firecracker. The setup is not simple though.
https://github.com/kata-containers/documentation/wiki/Initia...
Overall, fly.io building infrastructure on this pattern is fantastic and making it accessible is fantastic. Looking forward to seeing how this continues to evolve and am happy to see more infra build on top of firecracker. Very exciting!

Automating deployment to kubernetes
If you are deploying simple manifests (not helm-stuff), try shopify's [krane](https://github.com/Shopify/krane). I build a [deploy-container](https://github.com/strowi/deploy/) for use with gitlabs ci-stages a while back.

Using Ansible to deploy k8s manifests
If you have the flexibility to use a different tool https://github.com/Shopify/krane is a great one which among other things does compare what's on the cluster vs what's applied and can prune resources accordingly
What are some alternatives?
grype - A vulnerability scanner for container images and filesystems
lens-resource-map-extension - Lens - The Kubernetes IDE extension that displays Kubernetes resources and their relations as a force graph.
kubevirt - Kubernetes Virtualization API and runtime in order to define and manage virtual machines.
gluster-kubernetes - GlusterFS Native Storage Service for Kubernetes
simplenetes - The sns tool is used to manage the full life cycle of your Simplenetes clusters. It integrates with the Simplenetes Podcompiler project podc to compile pods.
