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

What's your take if DevOps colleague always got new initiative / idea?
Depends. When I came into my last company I immediately noticed the lack of reproducible environments. Brought this up a few times and was met with some resistance because "we didn't have the capacity"... Until prod went down and it took us 23 hours to bring it back up due to spaghetti terraform.

Questions about Rancher Launched/imported AKS
For the latest releases of rancher: https://github.com/rancher/rancher/releases When is Rancher 2.7.1 going to be released? The Rancher support matrix for 2.7.1 shows k8s v1.24.6 as the highest supported version and Azure will drop AKS v1.24 in a few months... Should this be a concern for us? What could happen if we create our cluster with Rancher for an unsupported K8s version? 1.25 for example. - Rancher 2.7.2 just got released including support for 1.25. I have however tested running unsupported versions before, unless there is major deprecations in the kubernetes API it is fine in my experience. If we move to AKS imported clusters, in case we add node pools, and upgrade the cluster, will those changes be reflected in the Rancher Platform? - Yep! If we face some issues by running an unsupported K8s version on Rancher Launched K8s clusters, is it possible to remove it from Rancher, do the stuff we need, and then import it into the platform? - Yes, however be careful and do testing before doing in prod. From top of mind: Remove cluster from rancher (if imported), if rancher created you might want to revoke ranchers SA key for the cluster first (so it can't remove it). Delete the cattle-system namespace, and any other cattle-* namespaces you don't want to keep. And do your thing. It looks like AKS is faster than Rancher regarding supported Kubernetes versions... We would like to know if Rancher will always be on track with AKS regarding the removal of K8s version support and new versions. - In my experience yes. (Been using rancher on all three clouds for a 4 years now). What are exactly the big differences between imported AKS and Rancher-launched AKS? What should we look at, and what issues can we face when using one or another? - The main difference is that rancher will not be able to upgrade the cluster for you. You will have to do that yourself.

Google and Microsoft’s chatbots are already citing one another in a misinformation shitshow
When I searched DuckDuckGo instead, the 12th link actually had the real answer. It's in this issue on Rancher's GitHub. Turns out the Rancher admin needs to be in all of the Keycloak groups they want to have show up in the auto-populated picklist in Rancher. Being a Keycloak admin and even creating the groups isn't good enough. Frustratingly, the "caveat" note the Rancher guy is pointing to that says this is only present in the guide to setting up Keycloak for SAML, but apparently this is also true for OIDC.
