text: Title: [Docker] Please export port 8000 for plesk
  Body: Hi there, merry Christmas!
  
  I am trying to install paperless-ng on a server using Plesk. It's working and I got it all running - but Plesk does not recognize the port you're exposing, which prevents me from actually accessing the service. I am using your docker image from https://hub.docker.com/r/jonaswinkler/paperless-ng
  
  I found this article, where they describe in the comments what needs to be done
  https://support.plesk.com/hc/en-us/articles/115003142213-Unable-to-add-Docker-Proxy-rules-in-Plesk-no-container-is-displayed
  
  The way I see it, all we'd need would be an EXPOSE 8000 in the docker file. But I am no expert and just guessing wildly. Would be much appreciated!
  
  Best,
  Jens
