Docker has been widely adopted and is used to run and scale applications in production. Additionally, it can be used to start applications quickly by executing a single Docker command.
Disk utilization in Docker for Mac Estimated reading time: 3 minutes 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.

Companies also are investing more and more effort into improving development in local and remote Docker containers, which comes with a lot of advantages as well.
You can get the basic information about your Docker configuration by executing:
The output contains information about your storage driver and your docker root directory.
The storage location of Docker images and containers
A Docker container consists of network settings, volumes, and images. The location of Docker files depends on your operating system. Here is an overview for the most used operating systems:
- Ubuntu:
/var/lib/docker/
- Fedora:
/var/lib/docker/
- Debian:
/var/lib/docker/
- Windows:
C:ProgramDataDockerDesktop
- MacOS:
~/Library/Containers/com.docker.docker/Data/vms/0/
In macOS and Windows, Docker runs Linux containers in a virtual environment. Therefore, there are some additional things to know.
Docker for Mac
Docker is not natively compatible with macOS, so Hyperkit is used to run a virtual image. Its virtual image data is located in:
~/Library/Containers/com.docker.docker/Data/vms/0

/var/lib/docker

You can kill this session by pressing Ctrl+a, followed by pressing k and y.
Docker for Windows

The configuration and the virtual image to execute linux images are saved in the default Docker root folder.
C:ProgramDataDockerDesktop
If you inspect regular images then you will get linux paths like:
You can connect to the virtual image by:
There, you can go to the referenced location:
The internal structure of the Docker root folder
Inside
/var/lib/docker
, different information is stored. For example, data for containers, volumes, builds, networks, and clusters.Docker images
The heaviest contents are usually images. If you use the default storage driver overlay2, then your Docker images are stored in
/var/lib/docker/overlay2
. There, you can find different files that represent read-only layers of a Docker image and a layer on top of it that contains your changes.Let’s explore the content by using an example:
The LowerDir contains the read-only layers of an image. The read-write layer that represents changes are part of the UpperDir. In my case, the NGINX UpperDir folder contains the log files:
The MergedDir represents the result of the UpperDir and LowerDir that is used by Docker to run the container. The WorkDir is an internal directory for overlay2 and should be empty.
Docker Volumes
It is possible to add a persistent store to containers to keep data longer than the container exists or to share the volume with the host or with other containers. A container can be started with a volume by using the -v option:
We can get information about the connected volume location by:
The referenced directory contains files from the location
/var/log
of the NGINX container.Clean up space used by Docker
It is recommended to use the Docker command to clean up unused containers. Container, networks, images, and the build cache can be cleaned up by executing:
Additionally, you can also remove unused volumes by executing:
Summary
Docker is an important part of many people’s environments and tooling. Sometimes, Docker feels a bit like magic by solving issues in a very smart way without telling the user how things are done behind the scenes. Still, Docker is a regular tool that stores its heavy parts in locations that can be opened and changed.
Sometimes, storage can fill up quickly. Therefore, it’s useful to inspect its root folder, but it is not recommended to delete or change any files manually. Instead, the prune commands can be used to free up disk space.

Stable or Unstable?
Generally, if you're a new user or value stability use the stable version. It won't change very often. If you want to help test the latest improvements and features and can handle some occasional breakage, use the unstable version. Always back up your existing configuration before testing unstable releases.
