      When running a build inside a docker container, some commands don't work because they rely on the user being properly set. For example, ssh doesn't work with the following error:

       

      No user exists for uid 150.

       

      I think this could be solved by append to passwd on container startup, something like this (untested, for proof of concept):

      if [ "$(id -u)" != "0" ]; then

          echo "jenkins:x:$(id -u):$(id -g):Jenkins:${HOME}:/sbin/nologin" >> /etc/passwd

      fi

          Comment [ My above workaround can further be improved by adding "-v jenkins_etc:/etc" to the Jenkins docker run command line. That way /etc/passwd will be available to all agent containers.

          And if you do that, you don't need the {{environment{}}} variables I have above.  Unfortunately, you'll still need to override $HOME. ]
