试图在docker中的alpine
linux上安装GD依赖项.
我正在构建PHP5-fpm-alpine图像.
FROM PHP:5-fpm-alpine RUN docker-PHP-ext-install MysqLi RUN apk upgrade --update && apk add \ libfreetype6-dev \ libjpeg62-turbo-dev \ libmcrypt-dev \ libpng12-dev \ && docker-PHP-ext-install -j$(nproc) mcrypt \ && docker-PHP-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \ && docker-PHP-ext-install -j$(nproc) gd
我收到错误：
ERROR: unsatisfiable constraints:
libfreetype6-dev (missing):
required by: world[libfreetype6-dev]
libjpeg62-turbo-dev (missing):
required by: world[libjpeg62-turbo-dev]
libpng12-dev (missing):
required by: world[libpng12-dev]
我对高山发行的经验有限.它似乎不是很受欢迎,ergo信息很少或根本没有通过谷歌.
docker hub示例中的软件包名称适用于debian版本.你必须使用alpine的包裹.您可以在这里搜索高山包裹：
https://pkgs.alpinelinux.org/packages.
以下应该有效：
FROM PHP:5-fpm-alpine RUN docker-PHP-ext-install MysqLi RUN apk upgrade --update && apk add \ coreutils \ freetype-dev \ libjpeg-turbo-dev \ libltdl \ libmcrypt-dev \ libpng-dev \ && docker-PHP-ext-install -j$(nproc) iconv mcrypt \ && docker-PHP-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \ && docker-PHP-ext-install -j$(nproc) gd
