OpenShift Origin: Node not ready

Question

I appear to have some problem with my installation of OpenShift Origin.

When I get endpoints for the router, I get the following:

oc get endpoints --namespace=default --selector=router
NAME          ENDPOINTS   AGE
router-west   <none>      21m

Obviously the router should have at least one endpoint.

Im trying to follow the troubleshooting guide on https://docs.openshift.com/enterprise/3.1/admin_guide/sdn_troubleshooting.html#debugging-the-router however it does not provide assistance in the situation where the router has not endpoints.

When I get my list of nodes, I get:

oc get nodes
NAME                         LABELS                                              STATUS     AGE
openshift.hughestech.space   kubernetes.io/hostname=openshift.mydomain.com   NotReady   38d

When I describe the node, I get the following:

oc describe node openshift.mydomain.com

Where have I gone wrong? What do I need to do? Thanks

Restart the node service and see if that makes a difference in oc get nodes output.

systemctl restart origin-node

Unless your node is running you can cannot make a running router pod and resulting in no endpoints.
