Docker Desktop stores Linux containers and images in a single, large “disk image” file in the Mac filesystem. This is different from Docker on Linux, which usually stores containers and images in the
/var/lib/docker
directory.Where is the disk image file?
To uninstall Docker Toolbox from Mac, first simply download the following Docker Toolbox Uninstall Shell Script to your local machine. Use the Terminal application on your Mac (i.e. Press CMD + Space to open Spotlight Search and enter keyword 'Terminal') to change into the directory it was downloaded into (i.e. Cd /Downloads ), and then. Installed Windows via Boot Camp Assistant, but wish to remove it? Follow this easy-to-use tutorial. Subscribe Read full article ht.
To locate the disk image file, select the Docker icon and thenPreferences > Resources > Advanced.
The Advanced tab displays the location of the disk image. It also displays the maximum size of the disk image and the actual space the disk image is consuming. Note that other tools might display space usage of the file in terms of the maximum file size, and not the actual file size.
If the file is too big

If the disk image file is too big, you can:
- move it to a bigger drive,
- delete unnecessary containers and images, or
- reduce the maximum allowable size of the file.
Move the file to a bigger drive
To move the disk image file to a different location:

Do not move the file directly in Finder as this can cause Docker Desktop to lose track of the file.
Delete unnecessary containers and images
Check whether you have any unnecessary containers and images. If your client and daemon API are running version 1.25 or later (use the
docker version
command on the client to check your client and daemon API versions), you can see the detailed space usage information by running:Alternatively, to list images, run:
and then, to list containers, run:
If there are lots of redundant objects, run the command:
This command removes all stopped containers, unused networks, dangling images, and build cache.
It might take a few minutes to reclaim space on the host depending on the format of the disk image file:
- If the file is named
Docker.raw
: space on the host should be reclaimed within a few seconds. - If the file is named
Docker.qcow2
: space will be freed by a background process after a few minutes.
Space is only freed when images are deleted. Space is not freed automatically when files are deleted inside running containers. To trigger a space reclamation at any point, run the command:
Note that many tools report the maximum file size, not the actual file size.To query the actual size of the file on the host from a terminal, run:

KB, whereas the maximum size of the disk is 64
GB.Reduce the maximum size of the file
To reduce the maximum size of the disk image file:
- Select the Docker icon and then select Preferences > Resources > Advanced.
- The Disk image size section contains a slider that allows you to change the maximum size of the disk image. Adjust the slider to set a lower limit.
- Click Apply & Restart.
When you reduce the maximum size, the current disk image file is deleted, and therefore, all containers and images will be lost.
mac, diskHello Mike,
With the advent of APFS (Apple File System) with MacOS HighSierra, Disk Utility acquired some additional capabilities that allow it towork with APFS and its support for containers.
The new APFS system has a basic container storage unit thatconsists of various volumes. These volumes are the logical drives that we viewin Finder. Therefore, to reclaim the space on its drive, users often delete theAPFS partition. Nevertheless, this might be a little complicated.
Before you proceed, make sure that you have taken a completebackup of your data after that you need to take the assistance of Disk Utilityand Terminal to delete APFS partition on macOS Sierra. Even if you have usedthe Disk Utility tool to undo the APFS system, chances that you would find thecontainer of APFS. To merge partitions and save more space, you have to deletethe existing APFS partition on MacOS Sierra
1. To start with, you need to go to SystemPreferences and launch the Disk Utility tool. On the left panel, you can viewthe APFS container for your Mac.
2. Simply select the APFS container andright-click it. From the provided options, click on 'Eject'.
3.As theAPFS container would be ejected, you can delete it. To do this, you need tolaunch Terminal on your Mac.
