Docker php 7.1 想象

Question

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

Answer 1

@Exadra37 的答案是正确的。但请注意，您还可以在安装 PHP 扩展后删除一些 APT 包（它们仅在编译/安装扩展时需要，而不是使用它 - 您将节省近 200 MB）：

FROM php:7.1

RUN apt-get update && \
    apt-get install -y libmagickwand-dev && \
    pecl install imagick && \
    docker-php-ext-enable imagick && \
    apt-get remove --purge -y automake autotools-dev bzip2-doc fontconfig gir1.2-freedesktop gir1.2-gdkpixbuf-2.0 gir1.2-glib-2.0 gir1.2-rsvg-2.0 icu-devtools javascript-common libblkid-dev libbz2-dev libcairo-gobject2 libcairo-script-interpreter2 libcairo2 libcairo2-dev libcroco3 libdatrie1 libdjvulibre-dev libdjvulibre-text libdjvulibre21 libelf1 libexif-dev libexif-doc libexif12 libexpat1-dev libffi-dev libfontconfig1-dev libfreetype6-dev libfribidi0 libgdk-pixbuf2.0-0 libgdk-pixbuf2.0-bin libgdk-pixbuf2.0-common libgdk-pixbuf2.0-dev libgirepository-1.0-1 libglib2.0-bin libglib2.0-data libglib2.0-dev libglib2.0-dev-bin libgraphite2-3 libharfbuzz0b libice-dev libice6 libicu-dev libilmbase-dev libilmbase23 libjbig-dev libjpeg-dev libjpeg62-turbo-dev libjs-jquery libjxr-tools libjxr0 liblcms2-dev liblqr-1-0-dev libltdl-dev liblzma-dev liblzo2-2 libmagickcore-6-arch-config libmagickcore-6-headers libmagickcore-6.q16-6-extra libmagickcore-6.q16-dev libmagickwand-6-headers libmagickwand-6.q16-dev libmagickwand-dev libmount-dev libmpdec2 libopenexr-dev libopenexr23 libopenjp2-7-dev libpango-1.0-0 libpangocairo-1.0-0 libpangoft2-1.0-0 libpcre16-3 libpcre3-dev libpcre32-3 libpcrecpp0v5 libpixman-1-0 libpixman-1-dev libpng-dev libpng-tools libpthread-stubs0-dev libpython3-stdlib libpython3.7-minimal libpython3.7-stdlib libreadline7 librsvg2-2 librsvg2-common librsvg2-dev libselinux1-dev libsepol1-dev libsm-dev libsm6 libthai-data libthai0 libtiff-dev libtiffxx5 libtool libwmf-dev libwmf0.2-7 libx11-dev libxau-dev libxcb-render0 libxcb-render0-dev libxcb-shm0 libxcb-shm0-dev libxcb1-dev libxdmcp-dev libxext-dev libxml2-dev libxrender-dev libxrender1 libxt-dev libxt6 mime-support python3 python3-distutils python3-lib2to3 python3-minimal python3.7 python3.7-minimal readline-common shared-mime-info uuid-dev x11-common x11proto-core-dev x11proto-dev x11proto-xext-dev xorg-sgml-doctools xtrans-dev zlib1g-dev && \
    rm -rf /var/lib/apt/lists/*

管理所需 APT 包的列表可能会很混乱，因此我开发了一个脚本来做到这一点。你可以简单地写这样的东西：

FROM php:7.1

COPY --from=mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/bin/

RUN install-php-extensions imagick

该脚本支持此处列出的install-php-extensionsPHP 扩展

Answer 2

来自官方docker 镜像文档：

“E: 包 'php-XXX' 没有安装候选”

从 docker-library/php#542 开始，这个镜像阻止了 Debian 的 PHP 包的安装。在 docker-library/php#551（评论）中有一些关于此更改的额外讨论，但要点是在此映像中安装 Debian 的 PHP 软件包会导致在单个映像中安装两个相互冲突的 PHP，这几乎肯定不是预期的结果。

对于那些被此更改破坏并在开发适当修复程序的同时寻找解决方法的人，将以下简单行添加到您的 Dockerfile 应删除该块（强烈警告，这将允许安装第二个安装PHP，这绝对不是你要找的东西，除非你真的知道你在做什么）：

运行 rm /etc/apt/preferences.d/no-debian-php

此错误的正确解决方案是使用 FROM debian:XXX 并直接安装 Debian 的 PHP 包，或者使用 docker-php-ext-install、pecl 和/或 phpize 安装必要的附加扩展和实用程序。

解决方案

Dockerfile：

FROM php:7.1

RUN apt update && \
    apt upgrade && \
    apt install -y libmagickwand-dev --no-install-recommends && \
    pecl install imagick && docker-php-ext-enable imagick && \
    rm -rf /var/lib/apt/lists/*

使用以下命令构建它：

$ sudo docker build -t exadra37/php-imagick:7.1 .

... some output ommitted ....
