我有一個使用 docker-compose 部署運行的 LAMP 應用程序。docker-compose.yml：app_web: depends_on: - app_db build: ./web ports: - '3000:80' volumes: - ./web/www:/var/www/html environment: - MYSQL_DATABASE=appdb - MYSQL_USER=appuser - MYSQL_PASSWORD=password文件： FROM php:7.4-apache WORKDIR /var/www RUN apt-get update \ && apt-get install -y wget \ && rm -rf /var/lib/apt/lists/* RUN apt-get update \ && apt-get install -y git RUN docker-php-ext-install pdo pdo_mysql mysqli RUN a2enmod rewrite COPY ./www /var/www/html這非常有效，為localhost:3000我提供了一個可用的網絡應用程序。我想使用 VSCode 遠程容器來改進我的調試。第 1 步是將它添加到我的 docker 實例中。我已經點擊Remote Containers: Add Development Container Configuration并選擇了“From docker-compose.yaml”然后選擇了app_web。然后我可以在容器中重新打開。這啟動了一些在 Docker Desktop 中看起來像以前一樣的東西，但是，Apache 沒有運行，當我啟動它時service apache2 start它無法訪問我從 PHP 設置的 ENV 變量，當我最初啟動它。

啊，所以，稍后想一想，.devcontainer\docker-compose.yml 以：
# Overrides default command so things don't shut down after the process ends.
command: /bin/sh -c "while sleep 1000; do :; done"
默認命令應該是 apache2-foreground，它在 php 圖像中啟動 Apache2。所以刪除它，并依靠主 dockerfile 末尾的命令來獲取 php 圖像解決了這個問題。
.devcontainer\docker-compose.yml
