Please add env var to specify the listening port

Hello,
Please add an environment variable to change the listening TCP port to something else than 8080. In a traditional bridge network Docker/Podman deployment, the host is NATing the port and we can remap it using the -p switch when deploying the container. However, when using a MacVlan or IPVlan network, no remap is available and we are forced to use port 8080.
Thanks!
