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 10001See also https://wiki.eclipse.org/Jenkins#My_build_fails_with_.22No_user_exists_for_uid_1000100000.22.2C_what.27s_the_issue.3F
