注意另一种修改 docker 存储路径的方式是：
新建 /etc/systemd/system/docker.service.d 目录，识别目录下的 .conf 文件为 docker 的配置文件，替换默认配置文件，即：
vi /etc/systemd/system/docker.service.d/docker.conf
Service
ExecStart=
ExecStart=/usr/bin/dockerd --graph=/home1/docker/lib
配置 docker 镜像加速与限制容器日志大小（根本上解决容器日志过多的问题：只对新建容器有效）
service docker stop &&
只配置加速，没有 NVIDIA-docker 时

安装 NVIDIA-docker 后，注意修改 daemon.json 文件（前半部分自动生成），如下：
{
"runtimes": {
"nvidia": {
"path": "nvidia-container-runtime",
"runtimeArgs": []
}
},
"registry-mirrors": ["https://ui528bum.mirror.aliyuncs.com"],
"log-driver":"json-file",
"log-opts": {"max-size":"100m", "max-file":"1"}
