Configuring the Docker storage volume
Contributors

Before installing Docker, you might need to format the Docker storage volume and mount it on /var/lib/docker
.
About this task
You can skip these steps if you plan to use local storage for the Docker storage volume and have sufficient space available on the host partition containing /var/lib
.
Steps
-
Create a file system on the Docker storage volume:
sudo mkfs.ext4 docker-storage-volume-device
-
Mount the Docker storage volume:
sudo mkdir -p /var/lib/docker sudo mount docker-storage-volume-device /var/lib/docker
-
Add an entry for docker-storage-volume-device to /etc/fstab.
This step ensures that the storage volume will remount automatically after host reboots.
