Let me lead you to study and learn this article "how to modify the storage location of Docker default image and container".

The details are as follows:

1. Why

The default image and container storage location of Docker is in / var/lib/docker. If we are just testing, we may not need to modify it, but when we use it a lot, we may want to default the storage location.

II. How

2.1 modify the docker.service file

Cd / etc/systemd/system/multi-user.target.wantsvim docker.serviceExecStart=/usr/bin/dockerd-graph=/data/docker-storage-driver=overlay-registry-mirror= https://jxus37ad.mirror.aliyuncs.com

-- graph=/data/docker:docker 's new storage location

-- storage-driver=overlay: the storage driver currently used by docker

Note: it seems that the storage driver will become overlay if it doesn't change.

2.2 restart docker

Systemctl daemon-reloadsystemctl restart docker# docker info
