In this article, you will get a brief overview of what Operators are and why it could be interesting to create them in Java. Future articles will show you how to create a simple Operator using the Java Operator SDK (JOSDK), an open source project that aims to simplify the task of creating Kubernetes Operators using Java.
As you can guess, this series of articles is principally targeted at Java developers interested in writing Operators in Java. You don't have to be an expert in Operators or Kubernetes. However, a basic understanding of all these topics will help.
