Docker php 7.1 imagick

Question

Docker php 7.1 imagick:-

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

• 没有可用的软件包“pel.php.net/imagick”安装失败
• 错误:服务“应用程序”生成失败

Answer 1

来自官方的码头形象文档：

"E：'php-XXX‘包没有安装选择“ 从docker-library/ PHP #542开始，此映像将阻止Debian的PHP包的安装。对于docker-library/ PHP #551 (注释)中的更改，还有一些其他的讨论，但要点是在此映像中安装Debian的PHP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。 对于那些在开发适当的修复程序时被此更改打破并寻求解决办法的人，在您的Dockerfile中添加以下简单行应该会删除这个块(请注意，这将允许安装PHP的第二次安装，这肯定不是您想要的，除非您真正知道您在做什么)： 运行rm /etc/apt/preferences.d/no-debian-php 解决此错误的正确解决方案是使用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/*

用以下方法构建：

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

@Exadra37 37的答案是正确的。但是请注意，在PHP扩展安装之后，您还可以删除一些APT包(只需要它们来编译/安装扩展，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/*

管理所需的APT包列表可能会很混乱，所以我开发了一个脚本来完成这个任务。您可以简单地编写如下内容：

FROM php:7.1

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

RUN install-php-extensions imagick

此install-php-extensions脚本支持列在这里扩展
