We run our regression tests in docker to make sure they not interfere however
plugins seems to force mounting /tmp:/tmp which is shared between containers,
which means tests will interfere with each other. I want to mount /tmp/${BUILD_NUMBER}:/tmp. However if I specify that build is failing because /tmp passed again with a different value (besides being passed twice and var not expanding which is different bug)
14:14:31 Error response from daemon: Duplicate bind mount /tmp
14:14:31 FATAL: Failed to run docker image
docker run --tty --detach --privileged --workdir /var/lib/jenkins/jobs/build-gerrit-master/workspace --volume /tmp/${BUILD_NUMBER}:/tmp:rw --volume /tmp/467:/tmp:rw --volume /var/lib/jenkins:/var/lib/jenkins:rw --volume /tmp:/tmp:rw
So it either should not pass /tmp mount point if it see that user defined one, or it should allow to complete override everything that plugin want to pass by default.
[JENKINS-36769] Cannot override /tmp volume mount

added a comment - besides shell script executions, is there anything else we should be aware of.
we also run into random temp file collision during heavy multi-active container builds in parallel

Mounting /tmp is required for executing shell build steps, the shell script is written in /tmp by the master/slave and read from the build container, if you don't share it directly, you'll have a FileNotFound.
