kubectl-describe:tldr:c90a6

The command "kubectl describe nodes ${node_name} -n ${namespace}" is used with the kubectl command-line tool to retrieve detailed information about a specific node in a Kubernetes cluster.

Here is a breakdown of the command:

• "kubectl": the command-line tool used to interact with the Kubernetes cluster.
• "describe": the command used to get detailed information about a specific resource.
• "nodes": the resource type we want to get information about, in this case, it is a node.
• "${node_name}": the name of the node you want to get information about. You need to replace "${node_name}" with the actual name of the node.
• "-n ${namespace}": an optional flag used to specify the namespace of the node. You need to replace "${namespace}" with the actual name of the namespace. If no namespace is specified, it defaults to the "default" namespace.

By running this command, you will get a detailed description of the specified node, including its status, resource usage, allocated pods, addresses, and more. This information can be useful for troubleshooting or monitoring purposes.
