Assuming the lakeFS container exposes port 8000 on the host network, there is a simple solution (not suitable for production, of course). Instead of pointing lakectl to 127.0.0.1, point it to the IP of your machine in the local network. For example, if your machine's IP is 10.0.0.1, point lakectl to
<http://10.0.0.1:8000/api/v1>
