Hello,

I got it to work with HA proxy. Below is the configuration that worked for me, sharing it here so others can benefit as well:

global
    log         127.0.0.1 local2

    chroot      /var/lib/haproxy
    pidfile     /var/run/haproxy.pid
    maxconn     4000
    user        haproxy
    group       haproxy
    daemon

    stats socket /var/lib/haproxy/stats

    ssl-default-bind-ciphers PROFILE=SYSTEM
    ssl-default-server-ciphers PROFILE=SYSTEM

defaults
    mode                    http
    log                     global
    option                  httplog
    option                  dontlognull
    option http-server-close
    option forwardfor       except 127.0.0.0/8
    option                  redispatch
    retries                 3
    timeout http-request    10s
    timeout queue           1m
    timeout connect         10s
    timeout client          1m
    timeout server          1m
    timeout http-keep-alive 10s
    timeout check           10s
    maxconn                 3000

frontend stats
    bind *:6666
    stats enable
    stats uri /stats
    stats refresh 10s
    stats admin if LOCALHOST

frontend main
    bind *:5000
    default_backend     registry
    option              forwardfor

backend registry
    mode http
    balance leastconn
    stick-table type string len 200 size 1m expire 30m
    stick on cookie(NXSESSIONID)

    option httpchk HEAD /web1 HTTP/1.0
    http-check expect ! rstatus ^5
    server  registry1 AAA.BBB.XXX.XX:5000 check cookie check
    server  registry2 AAA.BBB.YYY.YY:5000 check cookie check
    server  registry3 AAA.BBB.ZZZ.ZZ:5000 check cookie check

    option log-health-checks

    option redispatch
    timeout connect 1s
    timeout queue 5s
    timeout server 3600s

And my systemd unit, as icing on the cake :slight_smile:
