The Operator SDK makes it simple to build Kubernetes-native applications, providing the tools to build, test, and package Operators. The SDK also helps the developer to build Operators without requiring knowledge of Kubernetes API complexities.
In this article, we will create a sample Operator for deploying a sample application based on Spring Boot and Camel. This application is a simple Camel route that uses the undertow component. After building the Operator, we will deploy it on an OpenShift cluster.

The Operator Framework is an open source toolkit for managing Kubernetes-native applications. This framework and its features provide the ability to develop tools that simplify complexities, such as installing, configuring, managing, and packaging applications on Kubernetes and Red Hat OpenShift. In this article, we show how to use third-party APIs in Operator-SDK projects.
In projects built with Operator-SDK, only the Kubernetes API schemas are added by default. However, you might need to create, read, update, or delete a resource that is from another API—even one that you created yourself via other Operator projects.
Let’s check out an example scenario: How to create a Route resource from the OpenShift API for an Operator-SDK project.
