33-docker 存储路径更改

1.停止docker，把原有文件备份到新路径/data/docker

[root@docker01 docker]# systemctl stop docker
[root@docker01 docker]# cp -R ./* /data/docker/
[root@docker01 docker]# rm -rf /var/lib/docker

 

2.更能docker启动配置文件

[root@docker01 docker]# vim /usr/lib/systemd/system/docker.service
...
# for containers run by docker
ExecStart=/usr/bin/dockerd --graph=/data/docker
...

# 增加 --graph=/data/docker

3.重启docker

[root@docker01 docker]# systemctl daemon-reload
[root@docker01 docker]# systemctl start docker

4.验证路径

[root@docker01 docker]# docker info
