1. 先在宿主机创建挂载目录：mkdir -p /data/nginx/{conf,conf.d,html,logs}

  2. 然后把文件 nginx.conf 文件放到 /data/nginx/conf/

}

容器内 /etc/nginx/ 目录如下：

  1. 把子配置文件 default.conf 放到 /data/nginx/conf.d/

    server {
        listen       80;
        server_name  localhost;
     
        #charset koi8-r;
        #access_log  /var/log/nginx/host.access.log  main;
     
        location / {
            root   /usr/share/nginx/html;
            index  index.html index.htm;
        }
     
        #error_page  404              /404.html;
     
        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
     
        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}
     
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}
     
        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }

  2. 弄一个 index.html 放到 /data/nginx/html/

  3. nginx 日志会在运行后存到 /data/nginx/logs/ 目录

  4. 然后 docker run 直接运行 nginx：

    8
    docker run \
      --name myNginx \
      -d -p 8088:80 \
      -v /data/nginx/html/:/usr/share/nginx/html \
      -v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf:ro \
      -v /data/nginx/conf.d/:/etc/nginx/conf.d \
      -v /data/nginx/logs/:/var/log/nginx/ \
      nginx

  5. 另外如果用 docker-compose 或 swarm 起服务，docker-compose.yml 文件如下：

    version: "3"
    services:
       web:
         image: nginx
         ports:
           - "8082:80"
         volumes:
           - /data/nginx/html:/usr/share/nginx/html
           - /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf
           - /data/nginx/conf.d:/etc/nginx/conf.d
           - /data/nginx/logs:/var/log/nginx
         restart: always
         container_name: myNginx2

docker-compose up -d 启动服务

重新创建容器：docker-compose up -d –force-recreate
