我有Docker(docker-compose)的问题.我想使用安装一些PHP扩展docker-compose.yml,但我无法做到这一点,因为我的.yml有FROM ubuntu和没有FROM php.有什么方法可以实现或访问docker-php-ext-install？

Dockerfile

FROM ubuntu:16.04

RUN apt -yqq update
RUN apt -yqq install nginx iputils-ping
RUN docker-php-ext-install pdo pdo_mysql mbstring

WORKDIR /usr/local/src

COPY docker/nginx/dev.conf /etc/nginx/conf.d/dev.conf
COPY docker/nginx/nginx.conf /etc/nginx/nginx.conf

CMD ["nginx"]

泊坞窗,compose.yml

version: "2"
services:
  mariadb:
    image: mariadb
    environment:
      - MYSQL_ALLOW_EMPTY_PASSWORD=1
      - MYSQL_ROOT_PASSWORD=
  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    ports:
      - "8080:80"
    restart: always
    environment:
      - PMA_HOST=mariadb
    links:
      - mariadb
  php:
    image: php:7.1.1-fpm
    ports:
      - "9000:9000"
    volumes:
      - .:/dogopic
    links:
      - mariadb
  nginx:
    build: . …

我使用带有标记的php docker容器作为基础:

php:5.6-apache

我将它与mysql:5.6我可以在主持人处获得的基本图像相关联mysql.我创建了一个数据库,并用基本值填充了一个表.

然而,尝试访问我的应用程序,我得到:

Fatal error: Uncaught exception 'PDOException' with message

Docker php 7.1 想象：-

pecl install imagick \
&& docker-php-ext-enable imagick \

• 没有可用于包“pecl.php.net/imagick”的版本安装失败

• 错误：服务“应用程序”无法构建
