Risks of port forwarding

Hi all

As a workaround for BookStack, which has no ingress support I’m thinking about just implementing a port forwarding/opening for port 2665 to my homeserver. So I can reach BookStack from Outside my network via external_IP:2665.

But I’m not really sure about the possible risks, how docker container are hedged to each other.
Or with other words, are there serious risks in doing it like this, I mean it’s only forwarted to a docker container and the application BookStack. Or can this used as an entry point for the rest of my HA installation?

Thank you for your expertise
