Method: soft link

By default, the location of Docker is: / var/lib/docker

You can view the location with the following command:

[root@omisclass ~] # docker info | grep "Docker Root Dir" WARNING: You're not using the default seccomp profileDocker Root Dir: / var/lib/docker

Of course, the most direct way to solve this problem is to mount the partition to this directory, but there are other things on my data disk, which must be difficult to manage, so change the storage path of the image and container to achieve the goal.

This method will be implemented through soft connections.

First stop the Docker service:

Systemctl stop docker.service

Then move the entire / var/lib/docker directory to the destination path:

Mv / var/lib/docker / root/data/dockerln-s / root/data/docker / var/lib/dockersystemctl restart docker

At this time, when you start Docker, you find that the storage directory is still / var/lib/docker, but it is actually stored on the data disk, and you can see the capacity change on the data disk.
