new environment variable for port number

[orsomething1030]

The default port is set to 5800 for all your docker images and the default cannot be changed. For containers on my normal docker network this is fine since I can remap the ports in the compose file, but if I use a VPN docker network then all containers share the same network interface as the vpn client container.

For instance, the vpn client docker compose file would look something like this: vpn_client: image: dperson/openvpn-client ports: #ports for app containers' UI to be reachable from local network #firefox - "5801:5800" #jdownloader #- "5802:5800" .... etc

and then your docker containers would have in their compose section: network_mode: "service:vpn_client"

Since all your docker images share 5800 as the default port, I can't use more than one of them on my VPN docker network. Please add an environment variable to the base-image to change the default port number to allow cases like this.

Same problem here, while using with the realies/soulseek-docker container. Both use 5900 as the internal VNC port, with no option to change it. Would like to see a environment variable like INTERNAL_VNC_PORT.

I have tried several things today but no luck. Mapping a modified default_site.conf with a different port does not work, the container quits with ERROR: No modification applied to /etc/nginx/default_site.conf. Very frustrating. Maybe @jlesage can give some advice on how to change the default port. Workarounds welcome.

The next version of the base image I'm working on will have this functionality.

Note that this is a problem only when creating a container without using the default bridge network. Else, you can re-map ports using the -p parameter of the docker run command.

This is now supported with version 4.0.0 of images.
