They tell you it’s impossible, but it isn't: Building K8s Operators using Java and Jakarta EE
3Presented by Daniel Pfeifer (RedBridge) at EclipseCon 2022.
The industry seems to believe that the platform for our containers (Kubernetes) is exclusively based on Go to build the automations that we need. That is not the case, Kubernetes operators, controllers and webhooks are REST and HTTP and looking at Jakarta EE we have had RESTful WebServices for so very many years so why not use the specification you’re already used to in order to to build the custom automations you need?
In this session I will show how you how to build a Kubernetes Operator including the the often required webhooks in Java and just to put some sugar on top you may well walk away with some insights on how to best run your Java-stuff in containers. All of this based on north of five years of actual hands-on experience at running everything from small controllers to large monoliths in Kubernetes.
