1、下载 

docker pull nginx:latest

2、本地创建管理目录

mkdir -p /var/docker/nginx/conf
mkdir -p /var/docker/nginx/log
mkdir -p /var/docker/nginx/html

3、将容器中的相应文件复制到管理目录中 /usr/docker/nginx

docker run --name nginx -p 80:80 -d nginx

docker cp nginx:/etc/nginx/nginx.conf /var/docker/nginx/conf/nginx.conf
docker cp nginx:/etc/nginx/conf.d /var/docker/nginx/conf/conf.d
docker cp nginx:/usr/share/nginx/html /var/docker/nginx/

4、停止并移除容器

docker stop 容器ID
docker rm 容器ID

5、再次启动容器并作目录挂载

docker run \
-p 80:80 \
--name nginx \
--privileged=true \
-v /var/docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
-v /var/docker/nginx/conf/conf.d:/etc/nginx/conf.d \
-v /var/docker/nginx/log:/var/log/nginx \
-v /var/docker/nginx/html:/usr/share/nginx/html \
-d nginx

6、测试
