The set of commands docker port inspect and docker container inspect will not identify the

published port(s) for a container. The reason is that there is no such command as docker port

inspect. The correct command to inspect the port mappings of a container is docker port1. The

command docker container inspect can also show the port mappings of a container, but it will display

a lot of other information as well, so it isnot as concise as docker port2. To identify the published

port(s) for a container, you can use either of these commands:

docker port CONTAINER will list all the port mappings of the container1.

docker port CONTAINER PRIVATE_PORT will list only the port mapping of the specified private port of

the container1.

docker container inspect --format=' { {.NetworkSettings.Ports}}' CONTAINER will list only the port

mappings of the container in a JSON format23.

For example, if you have a container named web that publishes port 80 to port 8080 on the host, you

can use any of these commands to identify the published port:

$ docker port web

80/tcp -> 0.0.0.0:8080

$ docker port web 80

0.0.0.0:8080

$ docker container inspect --format=' { {.NetworkSettings.Ports}}'web

map[80/tcp:[map[HostIp:0.0.0.0 HostPort:8080]]]

:

docker port

docker container inspect

How can I grab exposed port from inspecting docker container?
