在Docker中管理数据
https://docs.docker.com/engine/admin/volumes/
挂载数据卷
修改nginx启动参数 例如开启gzip
docker run -d --name my-nginx001 -p 5555:80 -v /Users/qylinqylin/GitBook/Library/qylinfly/docker/share/examples/nginx/nginx.conf:/etc/nginx/nginx.conf:ro nginx:1.13.7-alpine
localhost:~ qylinqylin$ docker stop my-nginx001
my-nginx001
localhost:~ qylinqylin$ docker rm my-nginx001
这些还不够，我们要加载我们的页面才可以
docker run -d --name my-nginx001 -p 5555:80 -v /Users/qylinqylin/GitBook/Library/qylinfly/docker/share/examples//nginx/html:/usr/share/nginx/html:ro -v /Users/qylinqylin/GitBook/Library/qylinfly/docker/share/examples/nginx/nginx.conf:/etc/nginx/nginx.conf:ro nginx:1.13.7-alpine
何时需要挂载宿主机目录？PPT

如何使用
构建一个自己的镜像 Dockerfile 默认开启gzip
cd /Users/qylinqylin/GitBook/Library/qylinfly/docker/share/examples/nginx
docker build -t hwl-nginx:1.0 .
docker run -d --name my-nginx001 -p 5555:80 hwl-nginx:1.0
