Configure the Docker storage volume

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

1. Create a file system on the Docker storage volume:

   sudo mkfs.ext4 docker-storage-volume-device

2. Mount the Docker storage volume:

   sudo mkdir -p /var/lib/docker
   sudo mount docker-storage-volume-device /var/lib/docker

3. Add an entry for docker-storage-volume-device to /etc/fstab.

   This step ensures that the storage volume will remount automatically after host reboots.
