Chapter 15. Accessing odf-console with the ovs-multitenant plugin by manually enabling global pod networking

In OpenShift Container Platform, when ovs-multitenant plugin is used for software-defined networking (SDN), pods from different projects cannot send packets to or receive packets from pods and services of a different project. By default, pods can not communicate between namespaces or projects because a project’s pod networking is not global.

To access odf-console, the OpenShift console pod in the openshift-console namespace needs to connect with the OpenShift Data Foundation odf-console in the openshift-storage namespace. This is possible only when you manually eanble global pod networking.

Issue

  • When`ovs-multitenant` plugin is used in the OpenShift Container Platform, the odf-console plugin fails with the following message: 

    GET request for "odf-console" plugin failed: Get "https://odf-console-service.openshift-storage.svc.cluster.local:9001/locales/en/plugin__odf-console.json": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

Resolution

  • Make the pod networking for the OpenShift Data Foundation project global: 

    $ oc adm pod-network make-projects-global openshift-storage
