## Examples

```bash
$ docker ps

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                                            NAMES

```

### Find out all the ports mapped

```bash
$ docker container port test

7890/tcp -> 0.0.0.0:4321
9876/tcp -> 0.0.0.0:1234
```

### Find out a specific mapping

```bash
$ docker container port test 7890/tcp

0.0.0.0:4321
```

```bash
$ docker container port test 7890

0.0.0.0:4321
```

### An example showing error for non-existent mapping

```bash
$ docker container port test 7890/udp

2014/06/24 11:53:36 Error: No public port '7890/udp' published for test
