# Local setup
We use a `socat` container to forward ports from the VM to localhost (via Docker for Mac), to make it easier to access some VMs. To build
```
(cd dockerfiles; docker build -t socat -f Dockerfile.socat .)
```
And then run:
```
docker run --rm -t -d -p 8080:8080 socat tcp-listen:8080,reuseaddr,fork tcp:192.168.65.100:80
```
This forwards local port `8080` to `192.168.65.100:80`, so if you start, say the `intro` image, run `moby run -ip 196.168.65.100 intro`
