This project contains various samples for different usages of [Fabric8 Kubernetes Client](https://github.com/fabric8io/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"

```
