修改 docker 工作目录

一、停掉 containerd、cri-docker、docker

systemctl stop containerd
systemctl stop cri-docker
systemctl stop docker

二、拷贝 docker 工作目录下的所有文件到新路径

rsync -aP /var/lib/docker/ /docker/data/

三、daemon.json 添加新工作目录路径

{
  "registry-mirrors": [
    "https://oi87dmig.mirror.aliyuncs.com",
    "https://docker.mirrors.ustc.edu.cn",
    "https://hub-mirror.c.163.com",
    "http://mirror.baidubce.com",
    "https://registry.docker-cn.com"
  ],
   "data-root": "/docker/data",
   "log-driver": "json-file",
   "log-opts": {

    "max-size": "10m",
    "max-file": "3"

  }

}

四、重启 containerd、cri-docker、docker

systemctl daemon-reload
systemctl start containerd
systemctl start cri-docker
systemctl start docker
