How do you automate Helm charts installation?
I agree with Helm Operator, though it is in maintenance mode and on the cusp of replacement with a newer tool. I'm working with FluxCD org now, on the next generation of Helm Operator, check out Helm Controller, under the new Flux2 which is rapidly approaching 100% feature parity (in the sense of approaching a limit, it is for almost all use cases 100% feature parity already) with the stable Flux v1 + Helm Operator.

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::
