Unable to create a Docker container using a downloaded 3DSlicer version

Hi,
I have been trying to build a Docker image to run a given 3DSlicer version (5.2.2) on an HPC system. Once I have the base installation working, I will be willing to instal SlicerDMRI, UKFTractography and SlicerWMA extensions.

Although I have gone through the various related posts on the forum and even some repositories linked on those, I am unable to make the base installation work in the container.

My dockerfile is the following:

FROM ubuntu:22.04

LABEL version="1.0.0"
LABEL description="3DSlicer"

# Update + upgrade package management
RUN apt-get update && apt-get -y upgrade

RUN apt-get install -y wget

  mkdir -p ${SLICER_HOME} && \

  rm /tmp/Slicer.tar.gz

# Make Slicer available in the PATH
ENV PATH="${SLICER_HOME}:${PATH}"

The container is built successfully, but when I try to check that I can execute 3DSlicer, I get:

$ docker run 3dslicer Slicer --version
QFactoryLoader::QFactoryLoader() checking directory path "/opt/slicer/lib/QtPlugins/platforms" ...

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: xcb.

error: [/opt/slicer/bin/SlicerApp-real] exit abnormally - Report the problem.

This error has been reported in other threads, but none of the solutions proposed seem to get past the error. In fact, all lines between libx11-6 and RUN apt-get install -y '^libxcb.*-dev' that I have added after reading these threads have not modified the error message, so they could be removed from the above recipe.

What am I missing?

Thank you.

Also, not sure whether this will work nicely on an HCP system.
