- MetaController: Writing Kubernetes controllers can be simple
- What Is A Kubernetes Operator?
-
Why is Kubernetes adoption so hard?
It worth adopt proper controller development with something like Metacontroller, Kopf or Java Operator SDK.
- What is your approach to adding custom labels to a pod in a deployment that's managed by a helm chart?
-
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.
-
Is there a tutorial on how to write an Operator in Go?
You might like a little alternative to writing your own in the first instance:) take a look at https://metacontroller.github.io/metacontroller/
-
Writing an Operator from scratch
Codegen is not magic, but if you want to make it simple stupid, supportable and prod-usable I'd go for metacontroller. There's not much magic to it - just common admission/validation webhooks propagated to your controller implementation, alongside the simplest possible reconciliation cycle. We had adopted Knative driven metacontrollers and it's a pretty solid approach.

For what should I take a look?
https://github.com/metacontroller/metacontroller - Sounds cool! I will look into it.
-
Dynamic Mutating Pod Admission Controller?
When I need a quick mutating controller, I like to use MetaController, which makes rapid prototyping really easy: https://metacontroller.github.io/metacontroller/
-
Best option to write a CRD today?
If you are more into lightweight and common use cases, look at metacontroller or the shell-operator.
