Class OpenShiftTopologyConnector

java.lang.Object

org.wildfly.swarm.topology.openshift.runtime.OpenShiftTopologyConnector

All Implemented Interfaces:

org.jboss.msc.service.Service<OpenShiftTopologyConnector>, org.jboss.msc.value.Value<OpenShiftTopologyConnector>, TopologyConnector

public class OpenShiftTopologyConnector
extends Object
implements org.jboss.msc.service.Service<OpenShiftTopologyConnector>, TopologyConnector

Topology connector for OpenShift 3. This topology connector knows how to interact with the Kubernetes API in OpenShift 3 to provide topology information to other systems. For now it is read-only, exposing Kubernetes Services but relying on OpenShift methods to create and announces new services. The default service account for the OpenShift applications needs read access to the Kubernetes API. This can be done with a command like: oc policy add-role-to-user -z default view Relevant environment variables:

• $KUBERNETES_SERVICE_HOST - the hostname of the Kube API server, set automatically when running on OpenShift
• $KUBERNETES_SERVICE_PORT - the port of the Kube API server, set automatically when running on OpenShift
• $KUBERNETES_NAMESPACE - the Kube namespace to use - this is the project name when running on OpenShift. This will be auto-detected in some cases and an error will be thrown if the value can't be auto-detected and also is not set
