After completing the installation of a Kubernetes cluster on your NVIDIA DGX systems using BCM, how can you verify that all worker nodes are properly…

The kubectl get nodes command is the standard and authoritative method for querying the Kubernetes API server to determine the status of all nodes within the cluster. The output lists each registered node and its current status. A status of "Ready" indicates that the node's kubelet is healthy, has successfully registered with the control plane, and is fully prepared to accept and run pods. This single command directly and efficiently verifies the exact conditions specified in the question for all worker nodes simultaneously.

B. kubectl get pods shows the status of application workloads (pods), not the health or registration status of the underlying worker nodes themselves.

C. This manual method only verifies local services on an individual node; it does not confirm the node's registration or communication status with the Kubernetes control plane.

1. NVIDIA DGX SuperPOD with NVIDIA Base Command Manager Deployment Guide (v3.1.0): In the post-installation verification section, this guide explicitly instructs administrators to use kubectl get nodes to confirm that all nodes have joined the cluster and are in a ready state.

Reference: Section 5.1, "Verifying the Kubernetes Cluster," page 29. The guide states, "After the Kubernetes cluster is deployed, you can verify that the cluster is running and that all the nodes have joined the cluster," followed by the example command kubectl get nodes -o wide.

2. Official Kubernetes Documentation: The official documentation defines the kubectl get nodes command as the primary tool for listing nodes and describes the "Ready" condition as the key indicator that a node is healthy and able to run pods.

Reference: Kubernetes Documentation > Concepts > Architecture > Nodes > Node Status. The "Ready" condition in the status field signifies that the node is healthy and ready to accept pods.
