    This topic describes how to access the Kubernetes Dashboard UI and Grafana UI.

    Prerequisites

    • An E-MapReduce (EMR) Data Science cluster is created, and Kubeflow is selected from the optional services when you create the cluster. For more information, see Create a cluster.

    • Ports 32699 and 31808 are enabled. For more information, see Manage security groups.
