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!

Stop 'k rollout restart deploy' from restarting everything?
Anyway, I haven’t checked for sure as I’m away from laptop but it should be possible to use something like Kyverno to block that operation. We had to do similar in the past to hotfix a bug in our CLI tool. I wrote a blog post about it that might give you an idea: https://www.giantswarm.io/blog/restricting-cluster-admin-permissions

Kyverno - Kubernetes Native Policy Management

Admission controller to mutate cpu requests?
You could use a policy tool like kyverno or OPA.

Did I miss something here, regarding network policies and helm templates? (Slightly ranty)
You do still have to create a policy for every namespace, but don't have to worry about labeling individual pods. We're starting to move to Helm/kustomize for our namespaces to deploy default things like network policies to each one, and we're also starting to use kyverno more, which I think is a little more purpose built for this type of thing than metacontroller is.

kubernetes provider resources v1 vs non-v1 is it just me or is this dumb?
I knew it was unsupported so about 6 months ago I had started an effort to switch to Kyverno, which is far better and actually supported. The version of Kyverno I was using had a v1beta1 AdmissionController. Fortunately that was in a helm chart so easily caught by pluto before my upgrade.

Kyverno Policy As Code Using CDK8S
Kyverno Kyverno is a policy engine designed for Kubernetes, Kyverno policies can validate, mutate, and generate Kubernetes resources plus ensure OCI image supply chain security.
What are some alternatives?
grype - A vulnerability scanner for container images and filesystems
falco - Cloud Native Runtime Security
kubevirt - Kubernetes Virtualization API and runtime in order to define and manage virtual machines.
gatekeeper - 🐊 Gatekeeper - Policy Controller 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.
Kubewarden - Kubewarden is a policy engine for Kubernetes. It helps with keeping your Kubernetes clusters secure and compliant. Kubewarden policies can be written using regular programming languages or Domain Specific Languages (DSL) sugh as Rego. Policies are compiled into WebAssembly modules that are then distributed using traditional container registries.
