Hello,
This could be very useful when using as a docker image within plesk.
However within Plesk Proxy it is not possibel to use port routing for this container.
The problem is also described here: https://support.plesk.com/hc/en-us/articles/115003142213-Not-possible-to-add-Docker-Proxy-rules-no-container-is-displayed
But the solution to expose the port is already integrated in this image.
