## kubectl expose
|
|
|
|
Take a replicated application and expose it as Kubernetes Service
|
|
|
|
### Synopsis
|
|
|
|
|
|
Take a replicated application and expose it as Kubernetes Service.
|
|
|
|
Looks up a replication controller or service by name and uses the selector for that resource as the
|
|
selector for a new Service on the specified port. If no labels are specified, the new service will
|
|
re-use the labels from the resource it exposes.
|
|
|
|
```
|
|
kubectl expose RESOURCE NAME --port=port [--protocol=TCP|UDP] [--target-port=number-or-name] [--name=name] [--public-ip=ip] [--type=type]
|
|
```
|
|
|
|
### Examples
|
|
|
|
```
|
|
// Creates 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
|
|
|
|
// Creates 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
|
|
```
|
|
|
|

|
|
--protocol="TCP": The network protocol for the service to be created. Default is 'tcp'.
