Docker image works locally but not in CI build

Can anyone tell me where I'm going wrong with this attempt to mount?

sleep commands won’t help, the SSH feature (which you already tried since then) is to way to debug and it can stop the execution after a job. You are using sudo befoe the docker client command, but even without sudo the daemon is probably running as root and that is what matters. Even when you have permission issues for some reason, there should be an error message, not an empty folder in the container. Now I start to remember how Docker runs on CircleCI. I implemented my custom builder call…

You can find links to the circleci documentation which explains docker is running remotely unless you ask for a virtual machine not a container.
