Issue MESOS-3413: Docker containerizer does not symlink persistent volumes into sandbox
For the ArangoDB framework I am trying to use the persistent primitives. nearly all is working, but I am missing a crucial piece at the end: I have successfully created a persistent disk resource and have set the persistence and volume information in the DiskInfo message. However, I do not see any way to find out what directory on the host the mesos slave has reserved for us. I know it is ${MESOS_SLAVE_WORKDIR}/volumes/roles//_ but we have no way to query this information anywhere. The docker containerizer does not automatically mount this directory into our docker container, or symlinks it into our sandbox. Therefore, I have essentially no access to it. Note that the mesos containerizer (which I cannot use for other reasons) seems to create a symlink in the sandbox to the actual path for the persistent volume. With that, I could mount the volume into our docker container and all would be well.
