Thanks Pierre-Charles. This is exactly what is needed to make Mickael's image work on the cluster. 

Cheers,

Hi all,

I'm finally trying to create my own Docker image to run Wild Web Developer tests and runtime. WIP is at https://github.com/eclipse/wildwebdeveloper/blob/docker/docker/Dockerfile . The image seems correct locally (I can start vncserver, or at least it seems so) so I deployed it to hub.docker.com <http://hub.docker.com> ( https://hub.docker.com/r/mickaelistria/wildwebdeveloper-build-test-dependencies/ ) to be able to reference it in our Jenkinsfile ( https://github.com/eclipse/wildwebdeveloper/blob/docker/Jenkinsfile#L15 ) and use it during build.
However, when the image is used on ci.eclipse.org <http://ci.eclipse.org>, it's failing to start the vncserver with an error that looks like a user management issue:
`vncserver: Could not create //.vnc.` (from https://jenkins.eclipse.org/wildwebdeveloper/job/Wildwebdeveloper/job/docker/4/console ). This error makes me think it's because the current user of the Docker image is not named to it's not possible to infer a correct path.

Not sure this is the same issue (I can not see the console log you linked to), but the CBI images available at [1] had to perform some specific step regarding user id:

### user name recognition at runtime w/ an arbitrary uid - for OpenShift deployments
COPY scripts/uid_entrypoint /usr/local/bin/uid_entrypoint
RUN chmod u+x /usr/local/bin/uid_entrypoint && \
    chgrp 0 /usr/local/bin/uid_entrypoint && \
    chmod g=u /etc/passwd

ENTRYPOINT [ "uid_entrypoint" ]

and at the end:

USER 10001
