There was a project for that called docker sync (it could use of 3 mechanisms (one being rsync) to continually keep the files up to date in the container. The problem I found was it would just randomly stop syncing with no warnings or errors of any kind. It was very flaky. Nowadays make sure you use their new virtual machine thing in docker for Mac and add :cached in your compose file of any mounted volumes and I found that alleviated my issues. It used to be really bad though.
