Kubernetes Host: Validate the Worker Installation

Prerequisites

You have added the hosts as workers as described in Kubernetes Host: Add the Hosts as Workers.

Perform this procedure for each Kubernetes cluster you created.

About this task

Use the following procedure to validate each Kubernetes cluster you created.

Procedure

  1. Access the Services tab of the Kubernetes Administrator Dashboard screen (see Services Tab) and verify that the new Kubernetes Worker hosts appear and that all services are green.

    Hosts that are in a ready state and are not included in an existing Kubernetes cluster should have both the BD Agent and Monitoring Collector active. If the host has persistent disks, then the HPE Ezmeral Data Fabric services must also be enabled and active.

  2. If this host contains GPU devices, verify that those devices are available. See Using GPUs in Kubernetes Pods.
  3. Create and test a Kubernetes workflow as described in Getting Started with General Kubernetes Functionality and Kubernetes Cluster Usage Examples.
  4. Verify that the sample applications are generating the correct output.
  5. Access the Service Endpoints screen for each cluster you created.
  6. In the Services column, note the list of services (such as Hive thrift server, Mysql server, Spark master, and/or SSH) and the hostname:port combination listed for each service.
  7. Attempt to access each of the services using the hostname:port combination provided.
