You can run a Docker beacon node with the following command:
```bash
$ docker run -p 9000:9000 -p 127.0.0.1:5052:5052 -v $HOME/.lighthouse:/root/.lighthouse sigp/lighthouse lighthouse --network mainnet beacon --http --http-address 0.0.0.0

```
> To join the Pyrmont testnet, use `--network pyrmont` instead.

### Ports
In order to be a good peer and serve other peers you should expose port `9000`.
In order to be a good peer and serve other peers you should expose port `9000` for both TCP and UDP.
Use the `-p` flag to do this:
```bash
$ docker run -p 9000:9000 sigp/lighthouse lighthouse beacon
$ docker run -p 9000:9000/tcp -p 9000:9000/udp sigp/lighthouse lighthouse beacon
```
If you use the `--http` flag you may also want to expose the HTTP port with `-p
127.0.0.1:5052:5052`.
```bash
$ docker run -p 9000:9000 -p 127.0.0.1:5052:5052 sigp/lighthouse lighthouse beacon --http --http-address 0.0.0.0
$ docker run -p 9000:9000/tcp -p 9000:9000/udp -p 127.0.0.1:5052:5052 sigp/lighthouse lighthouse beacon --http --http-address 0.0.0.0
```
