haproxy-certbot container restart loop

[klairecodes]

When running the haproxy-certbot container (via docker-compose or otherwise), it does not start properly and instead enters a restart loop. This is all following these docs for version 3.3.4.1 on Fedora 36.

haproxy-certbot container logs from running using docker-start-services.sh from the Thingsboard repo:

iptables v1.8.4 (legacy): unknown option "--set-mark"
Try `iptables -h' or 'iptables --help' for more information.

Here is the line from the start.sh script that seems to be causing the issue:

docker/haproxy-certbot/docker/start.sh

Line 52 in 9712b3d

/sbin/iptables -t mangle -I OUTPUT -p tcp -s ${IP} --syn -j MARK --set-mark 1
