Overview

expose dynamically exposes a resource, which can be a pod, another service, a replication controller, deployment or replicaset as a new service. If no service type is explicitly specified, ClusterIP is assumed. Specific service types (NodePort, LoadBalancer, or ExternalName) can be requested with --type.

Expose a Pod

If a pod is used, the command reads the pod's labels and creates a service with a matching selector. By default, if no type is specified, ClusterIP is assumed.

kubectl [-n <namespace>] expose pod <pod-name> --port=<port> --target-port=<target-port> --name=<service-name> [--type=ClusterIP|NodePort|...]

kubectl expose pod httpd --port=9898 --target-port=80 --name=httpd-svc

Expose a Higher Level Controller

If a replication controller, deployment or replicaset are used, the command reads their selector and re-uses it for the service being created.
