Health Check Commands: Kubeflow Notebook Controllers

The Notebook Controller watches and manages Notebook custom resources that the Jupyter Web App creates. For each Notebook custom resource, the Notebook Controller syncs all Kubernetes resources that are needed to run a Jupyter Notebook server on Kubernetes. Please refer to the following commands to perform a health check or investigation into the Kubeflow Notebook Controllers.

1. Check the status of the Notebook Controller Deployment:

$ kubectl get deployment -n kubeflow notebook-controller-deployment -o wide

2. Inspect the events on the Notebook Controller Deployment:

$ kubectl describe deployment -n kubeflow notebook-controller-deployment

3. Check the status of the Notebook Controller Pod:

$ kubectl get pods -n kubeflow -l kustomize.component=notebook-controller -o wide

4. View Notebook Controller logs:

$ kubectl logs -n kubeflow deploy/notebook-controller-deployment -f
