If you use persistent data volumes in Docker, you might want to access them via command-line. If your docker host is Linux, that's not a problem; you can find Docker volumes by /var/lib/docker/volumes path. However, that's not the case when you use Docker for Mac. Try to cd /var/lib/docker/volumes from your MacOS terminal, and you 'll get nothing. You see, your Mac machine isn't a real Docker host. ![]() ![]() Docker Machine was the first approach to run Docker on either Mac or Windows. It is essentially a set of CLI tools that start a boot2docker virtual machine inside a provided hypervisor (like VirtualBox, Parallels, and VMWare). File system mounts are either provided via the hypervisor itself or (as the hypervisor is usually rather slow) an additional tool like NFS. Mac shortcut for strikethrough in gmail. Docker for Mac runs a virtual machine behind the scenes and hides it from you to make things simpler. Simpler, unless you want to dig deeper. So, to access persistent volumes created by Docker for Mac, you need to log in that hidden virtual machine first, which is not that straightforward. In order to accomplish this, we need to use a serial terminal on Mac. • We need to 'screen into' the Docker driver by executing a command: screen ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/tty • You should see a blank screen, just press Enter, and after a while, you should see a command line prompt • Now you're inside Docker's VM and you can cd into volumes dir by typing: cd /var/lib/docker/volumes • Profit, you got there! • If you need to transfer files from your MacOS host into Docker host (for example to put files into docker volumes) use directories shared between host (mac os) and Docker host (Docker VM), you can find a list of such directories under File Sharing tab of your Docker for Mac application. Hope this helps someone! Background Although helpfully goes out of its way to appear to be running natively on macOS, behind the scenes it actually runs on an Alpine Linux VM using. Refer to for more details. Under most circumstances we won’t need to understand the underlying implementation, but there are occasions where it is helpful to be able to see exactly what Docker is doing. In order to do this, we need access to the actual VM itself. This isn’t a problem when using as we can easily connect to the VirtualBox VM; it is not quite so obvious how to achieve this on the new architecture. I had it for years on a Mac. How to format a passport hard drive for mac. I can find it under Device Manager and Disk Management but that's it. Now either because of time, corruption or because it may have been formatted for a Mac when I plug it into my PC I cant access it. But unfortunately it bit the dust and I decided to get a PC. Accessing the Docker Device The callin device for the Docker VM can be found at ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/tty.
