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

5-Step Approach: Projectsveltos for Kubernetes add-on deployment and management on RKE2
In this blog post, we will demonstrate how easy and fast it is to deploy Sveltos on an RKE2 cluster with the help of ArgoCD, register two RKE2 Cluster API (CAPI) clusters and create a ClusterProfile to deploy Prometheus and Grafana Helm charts down the managed CAPI clusters.

“Ansible for DevOps” eBook by Jeff Geerling Is Now Free
4. Having moved to a container orchestrator, all of my nodes are immutable. Hardware and VM instances _can_ be born magically into existence. Nearly all infra providers support [cluster-api](https://cluster-api.sigs.k8s.io/). Network infrastructure can now be managed with TF, so I go that route.
- PR to docs are welcome.

Is it possible to install Rancher to manage an already functioning K8S?
You might find interesting the capi-rancher-import k8s operator we use in Sylva, it would adopt in Rancher server the Cluster API created k8s clusters (with bootstrap provider kubeadm or even rke2 - you can lookup CAPBR for the latter). I understand your clusters are not created by Cluster API, so if you could move the workloads/resources to new clusters created by Cluster API, this can come handy. (Adoption of non-CAPI clusters into CAPI is not yet a standard practice, more in https://github.com/kubernetes-sigs/cluster-api/issues/7776)

What tool suggestions do you have for someone who's gonna set up an on-premise k8 cluster? Which tools do you use?
Most of the comments have mentioned older tools like kubespray, Ansible, Rancher etc. I would suggest the cloud native way using ClusterAPI or use a tool that relies on ClusterAPI in the backend called Talos

Scaling Event-Driven Applications Made Easy with Sveltos Cross-Cluster Configuration
Sveltos is a powerful open source project that makes managing Kubernetes add-ons a breeze. It automatically discovers ClusterAPI powered clusters and allows you to easily register any other cluster (like GKE). Then, it seamlessly manages Kubernetes add-ons across all your clusters.
