  kubectl create clusterrole NAME --verb=verb --resource=resource.group [--resource-name=resource.name]
  kubectl create configmap NAME [--from-literal=key1=value1] [--from-literal=key2=value2] [--from-file=[key=]source] [--dry-run=server|client|none] [--output=wide|yaml|json] [options]
  kubectl create cronjob NAME --image=image [--schedule=''] --command -- [COMMAND] [args...] [options]
  kubectl create deployment NAME --image=image [--dry-run=server|client|none] [--output=wide|yaml|json] [options]
  kubectl create job NAME --image=image --command -- [COMMAND] [args...] [options]

Examples:
  # Create a pod using the data in pod.json.
  kubectl create -f ./pod.json

  # Create a pod based on the JSON passed into stdin.
  cat pod.json | kubectl create -f -

  # Edit the data in EDITOR (default vim).
  kubectl create configmap my-config --from-file=config.json --edit

  # Create a new namespace named my-namespace
  kubectl create namespace my-namespace

Options:
  -f, --filename='': Filename, directory, or URL to files to use to create the resource
  -k, --kustomize='': Process a kustomization directory. This flag can't be used together with -f or -R.
  --edit=false: Edit the data in $EDITOR
  --force=false: Create resource even if it already exists
  --dry-run='none': Must be "none", "server", or "client". If client strategy, only print the object that would be sent, without sending it. If server strategy, submit server-side request without persisting the resource.
  -o, --output='': Output format. One of: yaml, json, wide, name, go-template-file, go-template, jsonpath-file, jsonpath. If unspecified, will default to yaml for standalone objects and table for lists.
  --record=false: Record current kubectl command in the resource annotation. If set to false, do not record the command. If set to true, record the command. If not set, default to updating the existing annotation value only if one already exists.

在这个帮助文档中，你可以看到 `kubectl create` 命令支持不同类型的资源对象，包括 Pod、Deployment、Service、Secret 等。对于每个资源对象类型，文档都提供了示例和参数说明。
