Overview

expose dynamically exposes a resource, which can be a pod, service, replicationcontroller, deployment or replicaset as a new service.

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 replicset are used, the command

Expose a Service

The default service type is ClusterIP, other type (NodePort, LoadBalancer, or ExternalName) can be specified with --type.

kubectl [-n default] expose pod pg-0 --port=5432 --target-port=5432 --name=postgres --type=NodePort

TODO: I don't seem to see the service with kubectl get services, but attempting to connect to the database works.
