从入门到生产级配置详解Docker部署Nginx的实战指南

# 拉取官方最新镜像
docker pull nginx

# 运行容器，映射端口 80
docker run -d --name my-nginx -p 80:80 nginx

curl http://localhost

server {
    listen       80;
    server_name  localhost;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    # 错误页面

    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}
