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.

Annotations in Kubernetes Operator Design
The operator that I've been working on is designed to manage the full lifecycle of a QuestDB database instance, including version and hardware upgrades, config changes, backups, and (eventually) recovery from node failure. I used the Operator SDK and kubebuilder frameworks to provide scaffolding and API support.
-
Hacking in kind (Kubernetes in Docker)
I've recently been working on an operator (built using the operator-sdk) that manages cluster node lifecycles. Kind allows you to spin up clusters with multiple nodes, using a Docker container per-node and joining them using a common Docker network. However, the kind executable does not allow you to modify an existing cluster by adding or removing a node.

Creating Kubernetes Operators with operator-sdk
To illustrate what we can do with an operator, I will create a proof of concept using operator-sdk. According to the official website::
- What Is A Kubernetes Operator?
-
Writing a Kubernetes Operator
Besides the frameworks TFA lists, you can also build Operators in Ansible or Helm.

Using k8s-apiserver as AAA server for microservices?
Operator SDK is basically just a thin wrapper for kube-builder

What topics should I cover as DevOps in Golang after practice and learning syntax
You mean the Operator SDK? https://sdk.operatorframework.io

Dont understand how I can watch external resources modification/deletion with my custom operator
yes I agree with youu, an issue has been opened on the operator-sdk github page regarding this topic https://github.com/operator-framework/operator-sdk/issues/6117

7 Kubernetes Companies to Watch in 2022
Isovalent makes an enterprise version of Cilium, an open source tool that uses eBPF to provide security and observability for cloud native environments. Liz gave a great talk at KubeCon Los Angeles about eBPF that I highly recommend. My reaction to her talk was that I wished I had Cilium years ago to troubleshoot some difficult incidents. When I first heard about eBPF I had thought of it more from the observability standpoint, but Cilium also provides a CNI plugin, transparent encryption, logs for security audits, and much more.

Redundancy for apps
A lot of projects are currently heavily focused on K8S (like Cilium - ebpf service mesh).
