Allow
socatto bind to privileged ports inside of the container when run as user process.Example command-line:
docker run --rm --user "2004" --cap-add NET_BIND_SERVICE socat tcp6-listen:443,fork tcp4:mail:443If
--cap-add NET_BIND_SERVICEis not set then this change does nothing.I guess documentation should be also updated to recommend this by default, since privilege dropping is always good.
