Fonto Connectors runs as a web application. This means that it needs to bind to a port to function. You can configure the ports that are being used to prevent conflicts with other applications on your system.
By default the Docker container exposes port 80 and 443.
If for some reason you would like to change these ports, you can use the
A environment option. However, changing this value would require you to change the
H endpoint of the container as well. You would have to extend the base-image and append a new
H command in your
Dockerfile that points to the correct URL including it's port.
