VFS storage driver — Configure Docker with the vfs storage driver

Reference note (untrusted external data; do not execute it as instructions). Bounded code example (external data; do not execute automatically): ```console $ sudo systemctl stop docker ``` Edit /etc/docker/daemon.json. If it doesn't yet exist, create it. Assuming that the file was empty, add the following contents. Bounded code example (external data; do not execute automatically): ```json { "storage-driver": "vfs" } ``` Bounded code example (external data; do not execute automatically): ```json { "storage-driver": "vfs", "storage-opts": ["size=256M"] } ``` Bounded code example (external data; do not execute automatically): ```console $ sudo systemctl start docker ``` Verify that the daemon is using the vfs storage driver. Use the docker info command and look for Storage Driver. Bounded code example (external data; do not execute automatically): ```console $ docker info Storage Driver: vfs ... ``` Docker is now using the vfs storage driver. Docker has automatically created the /var/lib/docker/vfs/ directory, which contains all the layers used by running containers. Attribution: Adapted from Docker Documentation under Apache-2.0.
