# port
|
|
|
|
Usage: docker port CONTAINER [PRIVATE_PORT[/PROTO]]
|
|
|
|
List port mappings for the CONTAINER, or lookup the public-facing port that is
|
|
NAT-ed to the PRIVATE_PORT
|
|
|
|
You can find out all the ports mapped by not specifying a `PRIVATE_PORT`, or
|
|
just a specific mapping:
|
|
|
|
$ docker ps test
|
|
