Writing Kubernetes Sample Controller in Java

I recently saw this Sample Controller repository on kubernetes Github repository. This just implements a simple controller for watching CustomResource named Foo as defined within a CustomResourceDefinition.

I thought it would be a good idea to port this example which is written in GoLang to Java using Fabric8 Kubernetes Client


Fabric8 Kubernetes Java Client

Fabric8 Kubernetes Client recently released 5.0.0 version with a focus towards improved support regarding CustomResource and Kubernetes Operator related usage. It’s already integrated into Java Operator SDK.
