Fabric8 Kubernetes Client Demo

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"
