一.nginx.conf

     在/etc/nginx目录下配置nginx.conf文件，如果没有，直接touch生成

http {
   
     server {
        listen      80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

	client_max_body_size 20M;        

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
              root /opt/dist-generator/;
              index index.html;
        }
        location /generator/ {
              proxy_pass http://192.168.5.21:8085;  //8085指的是应用的端口
        }

  }
}

二.docker-compose.yml

   在docker-compose.yml部署nginx镜像时注意挂载的目录

nginx:
  container_name: nginx
  image: nginx
  restart: unless-stopped
  ports:
    - 8080:80                  //这个80指的是nginx.conf监控的80端口，8080指外部访问的8080
  volumes:
      - /etc/nginx/nginx.conf:/etc/nginx/nginx.conf:ro
      - /opt/dist:/opt/dist
      - /opt/dist-generator:/opt/dist-generator     //挂载目录要与conf配置的一致
  environment:
    - TZ=Asia/Shanghai

networks:
  default:
    external:
      name: bridge

三.启动docker-compose

   在docker-compose.yml目录启动： docker-compose up -d 

四.访问8080端口查看
