无法让 nginx 解析器工作

当网络中的容器更改其 IP 时，我遇到了 nginx 问题，我可以在 Linux 操作系统中访问它，但 nginx 无法解析新 IP...我搜索了很多解决方案，我发现 nginx 告诉我们使用解析器指令，然后我尝试了它但没有任何变化....无法使这个解析器工作，有什么我应该检查的吗？我什么都试过了....

西蒙尼能帮我提供一些提示吗？

注意：我正在使用 ecs fargate。

先谢谢了。

docker-compose.yml：

Dockerfile 的“i*-根”：**

FROM node:16 as build-root

WORKDIR /app

ENV PATH /app/node_modules/.bin:$PATH

COPY map.json ./
COPY package.json yarn.lock ./
RUN yarn install

COPY . .

RUN yarn build

COPY ./public /app/dist/

FROM nginx:alpine

RUN rm /etc/nginx/conf.d/default.conf

COPY nginx/nginx-custom.conf /etc/nginx/conf.d/nginx-custom.conf
COPY nginx/nginx-custom443.conf /etc/nginx/conf.d/nginx-custom443.conf
COPY nginx/***-cert.pem /etc/ssl/certs/***-cert.pem
COPY nginx/***-private.pem /etc/ssl/certs/***-private.pem

WORKDIR /usr/share/nginx/html

COPY --from=build-root /app/dist .

CMD ["nginx", "-g", "daemon off;"]

nginx-custom.conf（我尝试在其中应用解析器解决方案）

server {
    listen 80 default_server;
    server_name default;
    root   /usr/share/nginx/html;
    index index.html index.htm;

    location / {
        try_files $uri $uri/ /index.html;
    }
    
    resolver 172.16.0.23 ipv6=off valid=10s;
    set $upstream_endpoint http://***-react;

    location /***-react/ {
        rewrite ^/***-react/(.*) /$1 break;
        proxy_pass $upstream_endpoint;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection keep-alive;
        proxy_set_header Host $http_host;
        proxy_set_header IdRef $http_IdRef;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;          
        fastcgi_read_timeout 999999;
        proxy_connect_timeout 999999;
        proxy_send_timeout   999999;
        proxy_read_timeout   999999;
        send_timeout 999999;
        fastcgi_buffers 16 16k; 
        fastcgi_buffer_size 32k;
    }
}

但是我之前是怎么说的呢，这个解析器指令改变了一切......看起来 nginx 一直在缓存 dns，我试过使用 google dns 8.8.8.8 或 /etc/resolve.conf 名称服务器，但一切正常......我有点困惑。

我按照 nginx 文档操作，其中说解析器指令应该可以解决这个问题。

我会用这个

https://github.com/nginx-proxy/nginx-proxy/tree/main/docs

version: '2'

services:
  nginx-proxy:
    image: nginxproxy/nginx-proxy
    ports:
      - "80:80"
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro

  whoami:
    image: jwilder/whoami
    expose:
      - "8000"
    environment:
      - VIRTUAL_HOST=whoami.example
      - VIRTUAL_PORT=8000
