Docker volumes are stored in a specific directory on the host filesystem managed by Docker, typically /var/lib/docker/volumes/ on Linux systems.
Docker volumes are stored in a dedicated directory on the host machine that Docker manages. On Linux systems, the default location is /var/lib/docker/volumes/ . Within this directory, each volume has its own subdirectory named after the volume, and the actual data is stored in a _data subdirectory . For example, a volume named 'my-volume' would be located at /var/lib/docker/volumes/my-volume/_data .
You can find the exact storage location of any volume using the docker volume inspect command. This command displays detailed information about the volume, including its mount point on the host filesystem . For example, running docker volume inspect my-volume will show output containing the Mountpoint field with the complete path where the volume's data is stored.
The default storage location can be changed by modifying the Docker daemon configuration. You can set a custom data-root in the /etc/docker/daemon.json configuration file to specify a different directory for all Docker data, including volumes . After changing this setting, you must restart the Docker daemon for the changes to take effect.
Docker manages volumes and stores them in a location isolated from other host processes .
