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.

Kubernetes: Virtual Clusters As Development Environments
Alternatives: The concept of virtual clusters is rather new, so only few solutions for it exist. However, there are also open-source proof-of-concepts for a virtual cluster technology, such as k3v or the project from the Kubernetes multi-tenancy SIG.

create a configmap when a new namespace get created
This seems like a pretty good fit for HNC. You can restrict users to only create subnamespaces, and then ensure that the configmaps in the parent namespaces get propagated to the children.

Virtual Clusters For Kubernetes - Benefits & Use Cases
Virtual Kubernetes clusters are still a very new topic, but they are already available today. The multi-tenancy working group has presented an experimental solution in this area. k3v by Darren Shepherd is another proof of concept implementation in the open-source community.

Kubernetes Failure Stories
In a way this reminds me of Kubernetes Virtual Clusters. Each virtual cluster has its own tenant control plane, namespaces. Multiple virtual clusters exist in a super cluster.

Best Practice: Should each collection of resources be in their own namespace?
As a side note, hierarchical namespaces are coming, which makes things even more flexible: https://github.com/kubernetes-sigs/multi-tenancy/tree/master/incubator/hnc

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

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?
fluent-bit - Fast and Lightweight Logs and Metrics processor for Linux, BSD, OSX and Windows
falco - Cloud Native Runtime Security
helmfile - Deploy Kubernetes Helm Charts
gatekeeper - 🐊 Gatekeeper - Policy Controller for Kubernetes
k3s - Lightweight Kubernetes [Moved to: https://github.com/k3s-io/k3s]
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.
