# Create a service for a replicated nginx, which serves on port 80 and connects to the containers on port 8000.
kubectl expose rc nginx --port=80 --target-port=8000

# Create a service for a replication controller identified by type and name specified in "nginx-controller.yaml", which serves on port 80 and connects to the containers on port 8000.
kubectl expose -f nginx-controller.yaml --port=80 --target-port=8000

# Create a service for a pod valid-pod, which serves on port 444 with the name "frontend"
kubectl expose pod valid-pod --port=444 --name=frontend

# Create a second service based on the above service, exposing the container port 8443 as port 443 with the name "nginx-https"
kubectl expose service nginx --port=443 --target-port=8443 --name=nginx-https

# Create a service for a replicated streaming application on port 4100 balancing UDP traffic and named 'video-stream'.
kubectl expose rc streamer --port=4100 --protocol=udp --name=video-stream

# Create a service for a replicated nginx using replica set, which serves on port 80 and connects to the containers on port 8000.
kubectl expose rs nginx --port=80 --target-port=8000

# Create a service for an nginx deployment, which serves on port 80 and connects to the containers on port 8000.

      --dry-run[=false]: If true, only print the object that would be sent, without sending it.
      --external-ip="": Additional external IP address (not managed by Kubernetes) to accept for the service. If this IP is routed to a node, the service can be accessed by this IP in addition to its generated service IP.
  -f, --filename=[]: Filename, directory, or URL to a file identifying the resource to expose a service
      --generator="service/v2": The name of the API generator to use. There are 2 generators: 'service/v1' and 'service/v2'. The only difference between them is that service port in v1 is named 'default', while it is left unnamed in v2. Default is 'service/v2'.
  -l, --labels="": Labels to apply to the service created by this call.
      --load-balancer-ip="": IP to assign to to the Load Balancer. If empty, an ephemeral IP will be created and used (cloud-provider specific).
      --name="": The name for the newly created object.
      --no-headers[=false]: 当使用默认输出格式时不打印标题栏。
  -o, --output="": Output format. One of: json|yaml|wide|name|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://releases.k8s.io/release-1.3/docs/user-guide/jsonpath.md].
      --output-version="": Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
      --overrides="": An inline JSON override for the generated object. If this is non-empty, it is used to override the generated object. Requires that the object supply a valid apiVersion field.
      --port="": The port that the service should serve on. Copied from the resource being exposed, if unspecified
      --protocol="": The network protocol for the service to be created. Default is 'TCP'.
      --record[=false]: Record current kubectl command in the resource annotation.
  -R, --recursive[=false]: Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
      --save-config[=false]: If true, the configuration of current object will be saved in its annotation. This is useful when you want to perform kubectl apply on this object in the future.
      --selector="": A label selector to use for this service. Only equality-based selector requirements are supported. If empty (the default) infer the selector from the replication controller or replica set.
      --session-affinity="": If non-empty, set the session affinity for the service to this; legal values: 'None', 'ClientIP'
  -a, --show-all[=false]: When printing, show all resources (default hide terminated pods.)
      --show-labels[=false]: When printing, show all labels as the last column (default hide labels column)
      --sort-by="": If non-empty, sort list types using this field specification.  The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
      --target-port="": Name or number for the port on the container that the service should direct traffic to. Optional.
      --template="": Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview].
      --type="": Type for this service: ClusterIP, NodePort, or LoadBalancer. Default is 'ClusterIP'.

      --alsologtostderr[=false]: 同时输出日志到标准错误控制台和文件。
