1.1. 帮助

$ kubectl explain --help
List the fields for supported resources

 This command describes the fields associated with each supported API resource. Fields are identified via a simple
JSONPath identifier:

  <type>.<fieldName>[.<fieldName>]

 Add the --recursive flag to display all of the fields at once without descriptions. Information about each field is
retrieved from the server in OpenAPI format.

Use "kubectl api-resources" for a complete list of supported resources.

Examples:
  # Get the documentation of the resource and its fields
  kubectl explain pods

  # Get the documentation of a specific field of a resource
  kubectl explain pods.spec.containers

Options:
      --api-version='': Get different explanations for particular API version (API group/version)
      --recursive=false: Print the fields of fields (Currently only 1 level deep)

Usage:
  kubectl explain RESOURCE [options]

Use "kubectl options" for a list of global command-line options (applies to all commands).
