DBSeer Docker on remote server

[Inception95]

Hi, thanks for the great effort on DBSeer! I am currently running DBSeer on AWS instance using the DBSeer Docker image, however, I couldn't start the UI correctly based the "Docker Usage Guide for DBSeer.pdf".

Here are my steps to fix this:

1. enable the X11 forwarding on aws instance
2. install and start Xming on my local Windows laptop
3. ssh to the aws instance and pull the DBSeer image
4. echo $DISPLAY to check if it is the current_ip:11.0
5. use DISPLAY_NUMBER=$(echo $DISPLAY | cut -d. -f1 | cut -d: -f2) to set the DISPLAY_NUMBER, which is 11 here
6. use socat TCP4:localhost:60${DISPLAY_NUMBER} UNIX-LISTEN:/tmp/.X11-unix/X${DISPLAY_NUMBER} & to set the DISPALY inside and outside the docker correctly
7. use the docker run -e DISPLAY -v /var/lib/postgresql/11/main/:/dbseer/dataset -v /tmp/.X11-unix/:/tmp/.X11-unix -v /root/.Xauthority:/root/.Xauthority --net=host --rm dongyoungy/dbseer /run_dbseer to start the UI, the .Xauthority should be mounted to the /root/ not /developer/ since the default user to the image is root.

Now I can start the UI.
