Docker modify storage path

Modify the default storage path of Docker

When Docker is installed by default, the /var/lib/docker/ directory will be used as the storage directory to store the pulled images and created containers, etc.

Modification method

1. Create a storage folder

mkdir -p /data/docker

2. Edit the /etc/docker/daemon.json file

{
   "data-root": "/data/docker"
}

3. Restart Docker

systemctl daemon-reload
systemctl restart docker

4. Check if the change is successful

docker info
