      The internal, integrated container image registry in OpenShift [1] must be enabled in order to start RHOAI Notebooks and Workbenches. Attempts to start Nodebooks or Workbenches when the image registry is not enabled will fail with an "InvalidImageName" error.

      Regardless of the number of nodes in the cluster, and its network condition (connected or disconnected), the internal image registry must be configured in order to allow Jupyter Notebooks be spawned from RHOAI dashboard.

      If internal image registry is not configured, the following error will appear:

      It will happen with all available notebook images, even with custom ones.

      Some kind of dependency warning should be raised when spawning notebooks, plus documentation reference (unless this dependency has to be removed).

       

      After configuring the internal image registry, spawning jupyter notebooks work.
