      Description

      I use `ssh-agent` within a docker (through the https://wiki.jenkins-ci.org/display/JENKINS/CloudBees+Docker+Pipeline+Plugin plugin). From the logs, the ssh-agent appears to start and load the proper credentials.

      However, if I were to use the credentials, those would not work at all. If I inspect the environment, I see that the `SSH_AUTH_SOCK` variable is set, however, if I inspect the content of the /tmp directory, there is no such file created.

      I thought it might have been permission related so I tried creating a plain file and a pipe file in the directory, both operations worked.

      Finally, I checked if the socket was created on the slave (and not within the docker container). That does not appear to be the case. Furthermore, the environment variable is only available within the container.
