📋 Script Details

HAProxy — TCP/HTTP load balancer and reverse proxy. Complements the UI-driven proxies already in the repo (nginxproxymanager, npmplus, zoraxy, traefik) for layer-4 balancing, health checking and failover, where a GUI proxy is not enough. Requested in discussion #3129.

  • Distribution package, nothing exotic: apt install haproxy.
  • Ships a working haproxy.cfg with sane defaults, TLS floor at 1.2 (ssl-min-ver TLSv1.2 no-tls-tickets), the standard errorfiles, a statistics page on 8404 with a generated password, and a commented frontend/backend example to copy.
  • haproxy -c -f validation runs both at install and in the update path — a syntax error stops the service, which takes every proxied site down with it, so the update aborts before restarting rather than after.
  • Note: there is no configuration UI by design; rules are written by hand. Certificates are not renewed by HAProxy, and it wants cert+key concatenated into one PEM. Both documented in the JSON.

    The HAProxy script is ready for testing:

    bash -c "$(curl -fsSL https://github.com/community-scripts/ProxmoxVED/raw/main/ct/haproxy.sh)"

    Default credentials:
    Username: admin

    HAProxy has no configuration UI. The install ships only a statistics page on port 8404 plus a commented frontend/backend example - you have to write your own rules in /etc/haproxy/haproxy.cfg.
    The generated password for the statistics page is in the 'stats auth' line of /etc/haproxy/haproxy.cfg.
    Always validate before restarting: 'haproxy -c -f /etc/haproxy/haproxy.cfg'. A syntax error prevents the service from starting, which takes every proxied site down with it. The update path in this script does that check automatically.
    For TLS, HAProxy expects certificate and key concatenated into a single PEM file. Certificates are not renewed by HAProxy itself - pair it with certbot or an ACME client.

    Note: This is not in the official repo yet—it's just a dev version! After merging into ProxmoxVE, it will need to be recreated.

    This isn't related to HAProxy, but
    if an exclamation mark (!) is included in the “Custom - Password” field, the script won't run.
    It would be best to either disallow it on the web form or wrap it in quotes (‘’) when submitting it.

    Just replaced a VM install of haproxy with this CT. So far so good.
