volumes and link are not working at te moment would like to have setup my own docker engine so that volume and link can work, but can’t do that at the moment because the base image is not called with this option "–privileged "
Which platform are you using? Docker volumes will not work (correctly) in CircleCI 1.0, nor in CircleCI 2.0 with the docker executor.
Using the machine executor in CircleCI 2.0 gives you full Docker power for things like volumes.
