paraview/parafoam not running in docker container

I am trying to use the version of openFoam supplied to run in a docker container.
In my hands, paraFoam/paraview stops with the following message:

bash-4.2$ paraview
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Reinstalling the application may fix this problem.
Aborted (core dumped)

But reinstalling did not solve the problem.
My versions are:

Ubuntu: 1604 LTS
openFoam: v_1706
docker: Docker version 1.12.6, build 78d1802

And from inside the Docker container

bash-4.2$: qmake -v
QMake version 3.1
Using Qt version 5.9.0 in /home/buzz2/pawan/OpenFOAM/ThirdParty-1706-docker/platforms/linux64Gcc/qt-5.9.0/lib

Some docs say that with QT5 the "platforms" directory should be put next to the executable.
How do I make this ? Tank-you and sorry if this is not the right place to ask.
