Hi,

Per https://www.haproxy.com/blog/truly-seamless-reloads-with-haproxy-no-more-hacks/

Haproxy 1.8's socket transfer mechanism would provide seamless reload, basically both haproxy-a/b would share the socket file.

exec haproxy -f /usr/local/etc/haproxy/haproxy.cfg -sf $(s6-svstat /var/run/s6/services/haproxy-b | egrep -o "pid \d+" | egrep -o "\d+") -x /var/run/haproxy.sock

Hey @hihellobolke, thanks so much for the info! I don't really do SD with this project in any of my work right now, but the seamless reload might replace the need for running two instances altogether if I'm understand it correctly!
