Change the Docker Installation folder

The **`/var/lib/docker/`** folder is the default Docker folder for Ubuntu, Fedora, and Deblan in a standard engine installation, used to store container images and logs.

To change the Docker folder:

1. Stop the Docker daemon.

 **`sudo service docker stop`**
2. Create a file called **`daemon.json`** under the **`/etc/docker`** directory with the following content:

 ```
 {
 "data-root": "<path to your Docker folder>"
 }
 ```
3. Copy the current data directory to the new one.

 **`sudo rsync -aP /var/lib/docker/ <path to your Docker folder>`**
4. Rename the old docker directory.

 **`sudo mv /var/lib/docker /var/lib/docker.bkp`**
5. After confirming that the change was successful, you can remove the backup file.

 **`sudo rm -rf /var/lib/docker.bkp`**
6. Start the Docker daemon.

 **`sudo service docker start`**
