Building

Build the project without running tests using:

./mvnw clean install -DskipTests

Integration tests

Minikube

Minikube is a tool that makes it easy to run Kubernetes locally. Minikube runs a single-node Kubernetes cluster inside a VM on your laptop for users looking to try out Kubernetes or develop with it day-to-day.

Follow the instructions for installing Minikube here.

To start the Minikube cluster run:

minikube start

You should see a message saying

Starting local Kubernetes cluster...
Kubectl is now configured to use the cluster.

Running the tests

Once the Minikube is up and running, you can run all integration tests.

First determine the master address using kubectl cluster-info command which should show something like:

Kubernetes master is running at https://192.168.99.100:8443
kubernetes-dashboard is running at https://192.168.99.100:8443/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard

Now set KUBERNETES_MASTER to point to the master address shown above and run the tests:

export KUBERNETES_MASTER=https://192.168.99.100:8443
export KUBERNETES_NAMESPACE=default
$ ./mvnw test

Google Container Engine

Create a test cluster and target it using something like (use your own project name, substitute --zone if needed):

gcloud container --project {your-project-name} clusters create "spring-test" --zone "us-central1-b" --machine-type "n1-highcpu-2" --scope "https://www.googleapis.com/auth/compute","https://www.googleapis.com/auth/devstorage.read_only","https://www.googleapis.com/auth/logging.write" --network "default" --enable-cloud-logging --enable-cloud-monitoring
gcloud config set container/cluster spring-test
gcloud config set compute/zone us-central1-b
gcloud container clusters get-credentials spring-test

Running the tests

Once the test cluster has been created, you can run all integration tests.

First determine the master address using kubectl cluster-info command which should show something like:

Kubernetes master is running at https://104.197.162.59
GLBCDefaultBackend is running at https://104.197.162.59/api/v1/proxy/namespaces/kube-system/services/default-http-backend
Heapster is running at https://104.197.162.59/api/v1/proxy/namespaces/kube-system/services/heapster
KubeDNS is running at https://104.197.162.59/api/v1/proxy/namespaces/kube-system/services/kube-dns
kubernetes-dashboard is running at https://104.197.162.59/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard

Now set KUBERNETES_MASTER to point to the master address shown above and run the tests:

export KUBERNETES_MASTER=https://104.197.162.59
export KUBERNETES_NAMESPACE=default
$ ./mvnw test
