You can't. The socket admin interface allows you to only disable existing servers and then re-enable them, but you can't add a completely new server. However you can reload haproxy so that it minimises and on some platforms eliminates dropping any existing connections. Probably your init script already does this with the reload-command. For example this blog post tells about this https://medium.com/@Drew_Stokes/actual-zero-downtime-with-haproxy-18318578fde6 but I've also hear that on modern linux kernels even the iptables syn trick isn't needed, but I can't confirm.
