Kubernetes Cluster screen

The top of this screen contains the following buttons:

The table on this screen contains the following information and functions:

  • Name: Name of the cluster. Clicking a Kubernetes cluster name opens the Kubernetes Cluster Details screen for that Kubernetes cluster. See Viewing Kubernetes Cluster Details.
  • Version: Version of Kubernetes running in the cluster.

    If the Kubernetes version number includes the phrase -hpe<n>, where <n> is a number, the host is running a Kubernetes version that is distributed by Hewlett Packard Enterprise, which uses the containerd runtime.

  • Resources: This column presents the following information:
    • Cores: Number of CPU cores.
    • Memory: Amount of RAM, in GB.
    • GPUs: Quantity of GPUs.

      If the GPU supports MIG, when you click the More Info link, GPU Details dialog shows information about the MIG configuration. For example:

      GPU Devices: The number of GPU devices.
      MIG device details

      If the GPU device does not support MIG, the GPU Details dialog lists the GPU devices, but shows N/A in MIG Status and in MIG Devices.

  • Details: Additional information about the cluster, such as the date and time it was created and the user who created it. For Data Fabric cluster, this column includes the following additional information:

    • Datafabric: Indicates yes, YES, true, or TRUE for Data Fabric Worker nodes.

    • Name of the Data Fabric associated with the cluster.

    • Links to the the Policy Viewer, the Grafana and Kibana services, and the Data Fabric Managed Control System. These links are not shown when the system is in Lockdown mode. See Lockdown Mode.
      NOTE Grafana and Kibana Endpoints are not available for Footprint-Optimized configuration.

    • Delete: Clicking the Delete button (trash can) deletes the current Kubernetes cluster. See Deleting a Kubernetes Cluster.
    • Edit: Clicking the Edit icon (pencil) opens the Edit Kubernetes Cluster screen. See Editing an Existing Kubernetes Cluster.
    • Access Kubernetes Dashboard: Clicking the Access Kubernetes Dashboard button (screen) opens the Kubernetes dashboard for this Kubernetes cluster. See Accessing the Kubernetes Dashboard.
    • Download Admin Kubeconfig: Clicking the Download Admin Kubeconfig button (down arrow) downloads the Administrator Kubeconfig file for the Kubernetes cluster. See Downloading Admin Kubeconfig.
