用docker和nginx部署前端项目，并且访问本地java网关gateway服务

docker pull nginx

version: "3"
services:
  nginx:
    image: nginx
    ports:
        - "8801:8801" # 前端项目访问端口(宿主机:容器内)
    volumes: # 数据卷目录映射(宿主机:容器内)
        - ./nginx.conf:/etc/nginx/nginx.conf # 配置文件
        - ./:/usr/share/nginx/html  # 项目html文件
        - ./log:/var/log/nginx  # 日志文件(方便排查问题，不要也可以)

worker_processes  1;

    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    upstream app-gateway { # 负载均衡
        server host.docker.internal:51601; # 网关服务的地址和端口
    }
    server {
        listen 8801;
        location / {
            root /usr/share/nginx/html;
            index index.html;
        }

        location ~/app/(.*) {
            proxy_pass http://app-gateway/$1;
            proxy_set_header HOST $host; # 不改变源请求头的值
            proxy_pass_request_body on; # 开启获取请求体
            proxy_pass_request_headers on; # 开启获取请求头
            proxy_set_header X-Real-IP $remote_addr; # 记录真实发出请求的客户端IP
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; # 记录代理信息
        }
    }
