成功调试并最终在 AWS 上运行我的服务器和 nginx 容器后，我开始收到以下日志

这是我的docker-compose.yml

version: '3.8'

services:
  server:
    image: **************.us-east-2.amazonaws.com/howdy-api-production:latest

      - public_assets:/app/shared/public
    ports:
      - 8000:8000
    networks:
      - howdynetwork

 nginx:
    image: nginx:alpine
    container_name: howdynginx
    platform: linux/amd64
    restart: always
    ports:
      - 80:80
    depends_on:
      - server
    volumes:
      - public_assets:/app/shared/public
      - ./nginx.conf:/etc/nginx/conf.d/default.conf
    networks:
      - howdynetwork

volumes:
   public_assets:

networks:
  howdynetwork:
    driver: bridge

这是我的 nginx.conf

upstream api {
  server server:8000;
}

server {
  listen 80;
  # Uncomment this line when you have your own domain for the api.
  # server_name example.org www.example.org;

  client_max_body_size 10m;
  keepalive_timeout 60s;

  access_log /dev/stdout;
  error_log stderr;

  location / {
    try_files $uri @api;
  }

  location @api {
    proxy_pass http://api;
    proxy_http_version 1.1;
    proxy_set_header Host $host;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Port $server_port;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_redirect off;
  }

  location /public {
    alias /app/public;
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

  error_page 500 502 503 504 /500.json;
  location = /500.json {
    return 500 '{"statusCode": 500, "message": "Something went wrong."}';
  }
}

有什么想法为什么会发生这种情况吗？

谢谢！

我尝试了几个不同的 Nginx nginx.conf 但每个碰巧都有相同的结果。

Answer 1

通过添加“/”API端点的路由解决了该问题。

在 nginx.conf 我有

location / {
    try_files $uri @api;
  }

告诉 Nginx 要 ping 哪个端点来检查运行状况。我在那里没有终点。
