This example will show how to deploy a Java application to a Kubernetes cluster using Maven. It requires to run a Couchbase server that can be easily started on AWS or using Docker.

1. package: Builds the WAR file

2. install: Builds the WAR and Docker image using it

3. exec:java: Runs the application with a Couchbase server running on localhost

4. fabric8:apply: Deploys the application to Kubernetes, require install target to be invoked first

   1. By default, the Kubernetes cluster is localhost. Set KUBERNETES_MASTER environment variable to point to Kubernetes master.

1. fabric8:build: Builds the Docker image and generated Kubernetes resources

2. fabric8:resource: Generates the Kubernetes configuration file in target/classes/META-INF/fabric8 directory

3. fabric8:cluster-start: Bootstrap a Kubernetes cluster using minikube (download, install and run)
