A Simple Java project demostrating usage of fabric8 kubernetes Java client

Fabric8 Kubernetes Client Demo

Java CI with Maven License Twitter

This project contains various samples for different usages of Fabric8 Kubernetes Client. I generally use them in my blogs or for testing.

How to Build?

Just need to run mvn clean install to compile project

How to run a specific sample?

In order to run a sample, you need to be logged into a Kubernetes/OpenShift cluster. You can either use minikube or minishift if you don't have access to a remote cluster.

You can load project as maven project in your IDE and can run sample from IDE. You can also run it from maven using exec-maven-plugin. For example, here is how you would run DeploymentDemo:

mvn exec:java -Dexec.mainClass="io.fabric8.DeploymentDemo"

Fabric8 Code Generation samples

  • CRD YAML -> Java POJO
