This is the Java REST client for the version 3 architecture of OpenShift based on Kubernetes. The implementation is a work in progress to provide functionality and features of the command-line interface and is used by JBoss Tools for OpenShift. For compatibility with OpenShift 2.x see https://github.com/openshift/openshift-java-client/.

IClient client = new ClientFactory().create(url, sslCertCallback);
client.setAuthorizationStrategy(new TokenAuthorizationStrategy("ADSASEAWRA-AFAEWAAA");
List<IProject> projects = client.list(ResourceKind.PROJECTS, "test-namespace");

You may either build from source using maven (mvn clean package) or get the prebuilt artifact from the maven central.
