我正在尝试将请求重定向到Docker容器服务上不同端口中的服务。
docker-compose.yml

nginx:
        image: nginx:1.23.3
        volumes:
          - ./nginx/default.conf:/etc/nginx/conf.d/default.conf
          - ./nginx/src:/etc/nginx/html
        depends_on:
          - pinpoint-web
        restart: always
        ports:
          - 81:80
        networks:
          support-network:

    pinpoint-web:
        image: "pinpointdocker/pinpoint-web:${PINPOINT_VERSION}"
        restart: always
        expose:
          - "9997"
        ports:
          - "9997:9997"
          - "8080:8080"
        networks:
          support-network:

我的Nginx配置：

upstream pinpoint-web {
        server pinpoint-web:8080;
    }

    server {
        listen 80;

        location /pinpoint-web {
            rewrite /pinpoint-web/(.*) http://pinpoint-web:8080/$1 break;
            proxy_pass http://pinpoint-web;
        }
    }

但是当我尝试“http：//localhost：81/pinpoint-web”时，我收到了如下错误：

{
     "timestamp": 1678301663635,
     "status": 404,
     "error": "Not Found",
     "message": "No message available",
     "path": "/pinpoint-web",
     "data": null
    }
