Spring Boot + OpenShift

This example shows how to use Fabric8 Maven plugin for generating OpenShift/Kubernetes resources of a Spring Boot application. Also shows how to use Arquillian Cube together with Fabric8 to run deployment tests to ensure that the application will work when deployed into OpenShift cluster.

Previous steps

• git clone [email protected]:lordofthejars/rest-springboot-openshift.git

• minishift start I have tested with OpenShift Origin 3.6.0

• oc login

Run tests

mvn clean verify -Popenshift,openshift-it -Denv.init.enabled=true -DenableImageStreamDetection=true

This command will compile project and run tests using Spring Test framework. After that uses Fabric8 Maven plugin to generate openshift.json, kubernetes.json and spring-boot-http-is.yml (for Image Stream generation).

Then it runs deployment test (io.openshift.booster.OpenShiftIT) which creates a temporal namespace (itest-xxxx), apply Fabric8 generated resources and finally when everything is deployed and up and running, it executes the test method.

Warning

Sometimes the first time you run Fabric8 Maven plugin you get an HTTP 504 error. Just rerun again the build and it will work.
