Vanilla deployment on OpenShift - 02jh - unable to connect to hub

Hello all,

I was finally able to deploy JupyterHub on OpenShift and all the resources are running, but I am unable to connect to it.

I don’t have anything configured yet and this is just a vanilla install with helm (empty config).

oc get pods
NAME                              READY   STATUS    RESTARTS   AGE

user-scheduler-75bdd8c74f-scxfj   1/1     Running   0          11m
oc get services
NAME           TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)        AGE
hub            ClusterIP    <none>        8081/TCP       12m
proxy-api      ClusterIP   <none>        8001/TCP       12m
proxy-public   LoadBalancer   <pending>     80:31066/TCP   12m

In OpenShift, I am creating a route to the proxy-public service:

oc get routes
NAME        HOST/PORT                                     PATH   SERVICES       PORT   TERMINATION   WILDCARD
notebooks          proxy-public   http   edge          None

But when I visit the URL, it just times out!

Looking at the hub container logs, it’s up and it should be accepting traffic:

What am I missing?

Figured it out, one of the network policies I had applied to make this deployment work was restricting traffic from external clients.

The policy was taken from here: Kubernetes - Api_request to the proxy failed with status code 599, retrying - #9 by dprateek1991

Had to change ingress to any peer to get it to work.
