方法一、修改 docker daemon的启动参数-g， --graph=""

# Path to use as the root of the Docker runtime. Default is /var/lib/docker.
# 如 docker -d --graph=/opt/docker
# 我们可以通过修改 docker daemon的配置文件的方式来保存我们修改，方法如下：
# 默认情况下，docker daemon 会有一个默认的configuration 文件，此外，我们可以新建一个名为“daemon.json”文件的文件，我们在这个文件中的定义，会覆盖默认配置文件的内容文件。
### 修改
cd /etc/docker
vim daemon.json
# 在daemon.json文件中加入新的存储位置，
{
      "data-root": "/data/docker"
}
# 重载load配置
systemctl daemon-load
# 重启docker
systemctl restart docker.serivce

# 查看已修改的docker存储位置
