move the socket  
```sh
# mv /var/run/docker.sock /var/run/docker.sock.original
```

redirect all socket communications to a tcp listener in port 1234  
```sh
# socat TCP-LISTEN:1234,reuseaddr,fork UNIX-CONNECT:/var/run/docker.sock.original
```

create a new proxy socket to be use by the application  
```sh
# socat UNIX-LISTEN:/var/run/docker.sock,fork TCP-CONNECT:127.0.0.1:1234
```

sniff the traffic  
```sh
# tcpdump -i lo -netvv port 1234
