In some applications you may want to have access to some ports of the Raspberry Pi (e.g. for SSH connection). To do so, you can set the `QEMU_HOSTFWD` enviroment variable of the container by adding one or more entries, separated by spaces, in the standard QEMU format (`protocol::hostip:hostport-guestip:guestport`).
Example using the `docker run` command to expose the SSH port from the Raspberry Pi to the Container (`-e` part) and from the Container to the Host (`-p` part):
Example using the `docker run` command to expose the SSH and MQTT ports from the Raspberry Pi to the Container (`-e` part) and from the Container to the Host (`-p` part):
```
docker run -it -e QEMU_HOSTFWD=tcp::5022-:22 -p 5022:5022 lukechilds/dockerpi
docker run -it -e QEMU_HOSTFWD="tcp::5022-:22 tcp::1883-:1883" -p 5022:5022 -p 1883:1883 lukechilds/dockerpi
```
Example using the `docker-compose.yml` file to achieve the same result:
