    这是一个创建于 400 天前的主题,其中的信息可能已经有所发展或是发生改变。

    当前所使用的用于构建镜像的 Dockerfile

    FROM php:7.1-fpm
    
    MAINTAINER Lestat Lee <[email protected]>
    
    #更新 apt-get 源 使用 163 的源,同时备份现有 sources.list
    RUN mv /etc/apt/sources.list /etc/apt/sources.list.bak && \
            echo "deb http://mirrors.163.com/debian/ jessie main non-free contrib" >/etc/apt/sources.list && \
            echo "deb http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list && \
            echo "deb-src http://mirrors.163.com/debian/ jessie main non-free contrib" >>/etc/apt/sources.list && \
            echo "deb-src http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list
    
    
    RUN apt-get update \
        && apt-get install -y \
        git \
        zlib1g-dev \
        libjpeg-dev \
        libpng-dev \
    && curl -sS https://getcomposer.org/installer \
            | php -- --install-dir=/usr/local/bin --filename=composer \
    && composer config -g repo.packagist composer https://packagist.phpcomposer.com \
        && composer global require hirak/prestissimo
    
    
    #安装 gd 库
    RUN docker-php-ext-install -j$(nproc) iconv
        #&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
        #&& docker-php-ext-install -j$(nproc) gd
    
    #安装 redis 扩展
    RUN pecl install redis-4.0.1 \
        && pecl install xdebug-2.6.0 \
        && docker-php-ext-enable redis xdebug
    
    EXPOSE 9000
    

    问题描述

    如果直接在上述 Dockerfile 目录执行docker build .,则会出现和下面一样的错误提示(下面的错误提示是我在没有安装 gd 扩展以及相关依赖的情况下构建镜像后进入到镜像内执行安装命令的提示),php7.1-fpm 默认系统是Debian GNU/Linux 9

    E: Unable to correct problems, you have held broken packages.
    

    在 google 上也找了很久,都说指定zlib1g的版本后可以解决这个问题,但是我在指定zlib1g版本后依然出现以下的提示

    [email protected]:/var/www/html# apt-get install -y zlib1g-dev=1:1.2.8.dfsg-2+b1 libpng-dev && docker-php-ext-install gd

    我在 php7.0-fpm 镜像的 gd 库安装过程中也遇到同样的问题 除此之外其他扩展安装都很顺利,想请教一下各位这可能是什么原因造成的呢?

    感谢关注,已经解决了,就是镜像源的问题 已更换为科大源

    参考 docker 的 PHP 扩展安装说明, 安装 iconv 扩展的那一行可以忽略,其它照抄就可以了
    https://store.docker.com/images/php

    PHP Core Extensions
    For example, if you want to have a PHP-FPM image with iconv and gd extensions, you can inherit the base image that you like, and write your own Dockerfile like this:

    ```
    FROM php:7.2-fpm
    RUN apt-get update && apt-get install -y \
    libfreetype6-dev \
    libjpeg62-turbo-dev \
    libpng-dev \
    && docker-php-ext-install -j$(nproc) iconv \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install -j$(nproc) gd
    ```

    还有就是不要用网易的源,因为很多很久没更新了。。。
    科大的源还是不错的,推荐一下: http://mirrors.ustc.edu.cn/help/debian.html
