Can't start qtcreator in docker

[ignacioi96]

As the title explains when running the command provided I get an error. Here it is:

`docker run -it -v /tmp:/tmp rain92/kobo-qt-dev qtcreator $DISPLAY
Authorization required, but no authorization protocol specified
qt.qpa.xcb: could not connect to display :1
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

/launch.sh: line 10: 7 Aborted (core dumped) qtcreator
`

pretty new to docker and I'm not sure what to do... any ideas?

found a solution by running the following on the command line.

xhost +local:

and then

docker run -it -e DISPLAY=$DISPLAY -v /tmp:/tmp rain92/kobo-qt-dev
once inside the container run

qtcreator
