使用composer在docker容器中缺少ext-gd

如何解决使用composer在docker容器中缺少ext-gd

我在其中安装了composer的一个docker容器。我的docker-composer.yml看起来像这样：

SELECT   SID,NAME,SUBJECT,( 
         CASE 
                  WHEN EXAMTYPE IN ('ASSIGNMENTS','PRACTICAL') THEN SUM(MARKS) 
                  ELSE 0 
         END) AS "ASSIGNMENTS + PRACTICAL",( 
         CASE 
                  WHEN EXAMTYPE = 'WRITTEN' THEN SUM(MARKS) 
                  ELSE 0 
         END) AS "WRITTEN"
FROM     MARKSHEET 
WHERE    EXAMTYPE IN ('ASSIGNMENTS','PRACTICAL','WRITTEN') 
GROUP BY SID,EXAMTYPE

我的dockerfile：

webserver:
  build: ./docker/php
  ports:
    - 80:80
  links:
    - mysql
  volumes_from:
    - app

composer:
    image: composer:2.0
    volumes_from:
      - webserver
    working_dir: /var/www/html

mysql:
    image: mysql:5.7
    environment:
      MYSQL_DATABASE: "${DB_NAME}"
      MYSQL_USER: "${DB_USER}"
      MYSQL_ROOT_PASSWORD: "${DB_ROOT_PW}"
      MYSQL_PASSWORD: "${DB_PW}"
    volumes_from:
      - data

data:
  image: mysql:5.7.31
  volumes:
    - /var/lib/mysql
  command: "true"
    
phpmyadmin:
  image: phpmyadmin/phpmyadmin
  ports:
    - 8080:80
  links:
    - mysql
  environment:
    PMA_HOST: mysql
  volumes:
    - ./docker/php/uploads.ini:/usr/local/etc/php/conf.d/uploads.ini

app:
  image: tianon/true
  volumes:
    - ./src/oxid:/var/www/html:delegated

现在，当我用FROM php:7.4.8-apache COPY php.ini /usr/local/etc/php/ COPY 000-default.conf /etc/apache2/sites-available/ COPY ./ssl/ssl.crt /etc/apache2/ssl/ssl.crt COPY ./ssl/ssl.key /etc/apache2/ssl/ssl.key RUN a2enmod rewrite RUN a2enmod expires RUN a2enmod headers RUN apt-get update RUN apt-get install -y zlib1g-dev libxml2-dev libfreetype6-dev libjpeg62-turbo-dev libmcrypt-dev libpng12.0 imagemagick RUN docker-php-ext-install mysqli soap pdo_mysql bcmath pdo RUN docker-php-ext-configure gd --with-freetype --with-jpeg RUN docker-php-ext-install gd RUN docker-php-ext-configure intl RUN docker-php-ext-install intl # Install opcache RUN docker-php-ext-install opcache RUN a2enmod ssl EXPOSE 80 EXPOSE 443 # Install APCu RUN pecl install apcu RUN echo "extension=apcu.so" > /usr/local/etc/php/conf.d/apcu.ini 打开index.php时，它说已安装并启用了GD。

但是phpinfo();给了我这个错误，我不太明白为什么。

• shopware / core [6.3.0.0，...，6.3.3.1]要求ext-gd *->从系统中丢失。安装或启用PHP的gd扩展。

有人可以告诉我如何为该作曲家程序启用GD。

谢谢！
