无法将proxy_server localhost:3000连接到nginx配置文件（docker-compose项目）

Question

以下docker-compose.yml文件位于两个不同的文件夹中：

server {
listen 80;
index index.html;
server_name localhost;
error_log  /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
root /var/www/html/public;

}


server {
listen          80;             # the port nginx is listening on
server_name     client.localhost;    # setup your domain here


 location / {


    proxy_redirect                      off;
    proxy_set_header Host               $host;
    proxy_set_header X-Real-IP          $remote_addr;
    proxy_set_header X-Forwarded-For    $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto  $scheme;
    proxy_read_timeout          1m;
    proxy_connect_timeout       1m;
    proxy_pass                          http://127.0.0.1:3000/; # set the address of the Node.js instance here
}
}

运行docker-compose logs-f nginx后出错

以下是front/docker-compose.yml：

version: "3.5"
services:
  client:
    build:
      context: .
      dockerfile: Dockerfile
    container_name: client
    ports:
      - "3000:3000"
    networks:
      - client_esl
networks:
  client_esl:
   external:
      name : nginx_esl

API/Docker-compose.yml

version: "3.5"

networks:
  esl:

services:
  site:
    image: nginx:stable-alpine
    container_name: nginx
    ports:
      - "80:80"
    volumes:
      - ./src:/var/www/html
      - ./nginx/default.conf:/etc/nginx/conf.d/default.conf
    networks:
      - esl

运行APK add Git

收到。/usr/src/nuxt-app/

运行NPM安装

如果要将2个容器连接在一起，有以下几种选择：

• 像您所做的那样向主机公开端口(3000:3000)，然后您可以从其他容器中使用这个端口+主机IP（不是本地主机，因为它指的是容器本身）
• 不要公开端口，如果容器位于同一网络中，请使用容器名称+端口，如Client:3000
