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.

Building a Kubernetes Operator with the Operator Framework
Kubernetes Operators simplify the management of complex applications on Kubernetes. In this guide, we'll walk through creating a simple Kubernetes Operator using the Operator Framework. We'll also cover setting up a local Kubernetes cluster with KIND (Kubernetes in Docker) and deploying the Operator to the KIND cluster.

Writing a Kubernetes Operator
Since Go got generics, working with the Kubernetes API could become far more ergonomic. It's been pulling teeth until now. I'm eager to see how the upstream APIs change over time.
In the mean time, one of the creators of the Operator Framework[0] built a bunch of useful patterns using generics that we used to build the SpiceDB Operator[1] called controller-idioms[2].
Does anyone know of other efforts to improve the status quo?

is there a way to set expiry date for k8s rbac setting?
There are many frameworks, like the Operator Framework (https://operatorframework.io/) to the MetaController (https://github.com/metacontroller/metacontroller) to KubeBuilder(https://github.com/kubernetes-sigs/kubebuilder) to the Kubernetes Operator Framework (kopf, https://kopf.readthedocs.io/en/stable/), among others.

How OLM helps to install and upgrade operators
Operator lifecycle manager (OLM) is a Kubernetes feature & is part of Operator framework which provides tools that helps in the development and management of operators. OpenShift 4.x is build using different operators that manages cluster components like api-server, etcd, authentication, OAuth, ingress, etc. OpenShift makes use of OLM to install these operators as part of cluster build & OLM comes by default with OpenShift. OLM is an operator itself and understanding how it manages the operator lifecycle using different CRD’s & its flow is important, which I have explained in my article.

Operators are so much easier to click-install -- how do I get them back out as manifests?
The documentation gives you all available options, but many of them are optional. If you know the package name of the operator (which you can get either via oc get packagemanifests or kubectl operator list-available from the kubectl plugin all you really need is:
