    ### Show all mapped ports

    You can find out all the ports mapped by not specifying a `PRIVATE_PORT`, or
    just a specific mapping:

    ```console
    $ docker ps

    CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                                            NAMES
