使用官方 Alpine Docker 映像将 yaml 扩展添加到 php
我正在使用这个官方的 php Docker 镜像:https://github.com/docker-library/php/blob/76a1c5ca161f1ed6aafb2c2d26f83ec17360bc68/7.1/alpine/Dockerfile
I'm using this offical php Docker image: https://github.com/docker-library/php/blob/76a1c5ca161f1ed6aafb2c2d26f83ec17360bc68/7.1/alpine/Dockerfile
现在我需要添加对 yaml 扩展的支持,它不与 php 捆绑在一起.我看到我正在使用的基本图像使用 phpize.
Now I need to add support for yaml extension, that is not bundled with php. I see the base image I'm using uses phpize.
我正在尝试这种方法:
FROM php:7.1.5-alpine
# Install and enable yaml extension support to php
RUN apk add --update yaml yaml-dev
RUN pecl channel-update pecl.php.net
RUN pecl install yaml-2.0.0 && docker-php-ext-enable yaml
但我得到这个错误:
running: phpize
Configuring for:
PHP Api Version: 20160303
Zend Module Api No: 20160303
Zend Extension Api No: 320160303
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.
ERROR: `phpize' failed
ERROR: Service 'php_env' failed to build: The command '/bin/sh -c pecl install yaml-2.0.0 && docker-php-ext-enable yaml' returned a non-zero code: 1
使用该图像并添加该支持的最惯用的 docker 方式是什么?
What is the most idiomatic docker way to use that image and add that support?
我应该使用它作为基础,还是可以添加参数以使想要的扩展可配置?
Should I use it as base, or is someway possible to add parameters in order to make wanted extension configurable?
推荐答案
Alpine 使用 apk 安装包.编译过程抱怨缺少 autoconf
,它位于 Alpine 的 autoconf
包中.
Alpine uses apk to install packages. The compiling process is complaining about missing autoconf
, which is found in Alpine's autoconf
package.
我建议你运行这些命令:
I'd suggest you to run these commands:
RUN apk add --no-cache --virtual .build-deps
g++ make autoconf yaml-dev
RUN pecl channel-update pecl.php.net
RUN pecl install yaml-2.0.0 && docker-php-ext-enable yaml
RUN apk del --purge .build-deps
如果您需要安装其他非开发库,您可以在单独的 apk add
命令中安装它们.此过程将:
If you need to install other non-dev libraries, you can install them in a separate apk add
command. This procedure will:
安装构建依赖,使用
--no-cache
意味着您正在使用更新的索引而不是本地缓存(因此不需要--update
或将 pkg 保存在缓存中).--virtual
表示您正在为所有那些以后可以删除的包创建一个虚拟引用(因为它们在编译过程之后无用)
install the build deps, using
--no-cache
means you're using an updated index and not cached locally (thus no need of--update
or to save the pkg in the cache).--virtual
means you're creating a virtual reference for all those packages that can later be deleted (because they're useless after the compiling process)
用 pecl 和 docker-php-ext-enable 做你的事情
do your stuff with pecl and docker-php-ext-enable
删除之前的构建deps
delete the previous build deps
如果您仍然遇到任何缺少的依赖项,您可以参考以下内容:https://pkgs.alpinelinux.org/包
