Glasskube Operator Architecture

Frameworks & Programming language

There are multiple possible solutions to build a custom operator on top:

• Go based "Operator Framework": https://sdk.operatorframework.io/docs/building-operators/golang/
• Java based "Java Operator SDK": https://javaoperatorsdk.io/

We decided to use the Java Operator SDK in combination with Kotlin.

@pmig why java over golang ? was it because the apps that are being deployed with glass kube are java based and interoperability would be easier ? I wanted to contribute to the operator but the language is what stopped me from doing so for now. Looking forward to heading why Java was chosen over GlassKube. I have worked with fabric8io Kubernetes client in my time at Red Hat when I used to work on the jenkins openshift plugins so was quite surprised to see it be used here as well.

we initially started out with Java / Kotlin due to our previous experiences with these languages. The operator is in maintenance mode and superseded by our package manager https://github.com/glasskube/glasskube/

Using the languages you know definitely makes the development quicker and java is good as well if you have a dependency on certain java libraries. But thanks for letting me know I will checkout the other repo.
