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.

How we wrote Tarantool Kubernetes Operator
The Tarantool ecosystem is constantly growing. Today it already has a lot of connectors for popular programming languages (Golang, Python, Java, etc.), extension modules for building applications with blocks (vshard, queue, etc.), and frameworks that speed up the development process (Cartridge and Luatest).

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

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
