docker-對dockerIP公開的80埠

我正在嘗試將域名指向我的 docker 容器。在我們的路由器中，我們將埠 80 轉發到192.168.1.101（服務器 Docker 正在運行）

然而，容器 IP 地址顯示為

"nextjs-docker-pm2-nginx-master-nextjs-1:172.18.0.2/16"
"nextjs-docker-pm2-nginx-master-nginx-1:172.18.0.4/16"

CONTAINER ID   IMAGE                                   COMMAND                  CREATED          STATUS          PORTS                                      NAMES

我的 default.conf 是

我們的 docker-compose 檔案是

services:
  nextjs: 
    build: ./DRN1Git
  nginx: 
    user: $UID
    build: ./nginx
    restart: always
    ports:
      - 80:80
      - 443:443
    volumes:
      - ./certbot/www:/var/www/certbot/:rw
      - ./certbot/conf/:/etc/nginx/ssl/:ro
  certbot:
    image: certbot/certbot:latest
    volumes:
      - ./certbot/www/:/var/www/certbot/:rw
      - ./certbot/conf/:/etc/letsencrypt/:rw

uj5u.com熱心網友回復：

默認情況下，Docker 創建一個內部網路。（172.18.0.0/16在你的情況下）。您需要將容器的埠映射到您的 docker 主機 ( 192.168.1.101) 的外部。請參閱compose 中的埠以供參考。例如：

version: "3.9"
services:
  web:
    build: nginx
      ports:
      - "80:80"

如果您提供您的docker-compose我將適合示例以滿足您的需求。
