mafamafa/haproxy-env-config repository overview

The primary feature of this project is its ability to forward incoming requests from a specified port on the host to a designated port on a target IP address. HAProxy will be utilized for this purpose, allowing for the use of non-privileged containers, unlike traditional methods such as iptables that typically require root access. Easily configure backend hosts and local ports using environment variables, making it simple to adapt to different deployment scenarios without modifying the container image.
