问题描述
正式的php7 docker镜像具有以下示例:
The official php7 docker image has the following example:
FROM php:7.0-fpm
RUN apt-get update && apt-get install -y libmemcached-dev \
&& pecl install memcached \
&& docker-php-ext-enable memcached
我正在尝试使用FROM php:7.0-fpm-alpine:
RUN apk add --update --no-cache libmemcached-dev
RUN pecl install memcached && docker-php-ext-enable memcached
PECL出现此错误:
PECL gives this error:

推荐答案
当前 php-memcached-dev:php7 分支包含此扩展的源.
Currently the php-memcached-dev:php7 branch contains the source for this extension.
要安装它，您仍然可以使用docker-php-ext-*命令，但是您需要自己签出源代码.
To install it you can still use the docker-php-ext-* commands but you need to checkout the source yourself.
假设已经安装了安装扩展程序所需的一切，则可以执行以下操作:
Assuming everything required to install the extension is already installed you can do:
RUN git clone -b php7 https://github.com/php-memcached-dev/php-memcached /usr/src/php/ext/memcached \
&& docker-php-ext-configure /usr/src/php/ext/memcached \
--disable-memcached-sasl \
&& docker-php-ext-install /usr/src/php/ext/memcached \
&& rm -rf /usr/src/php/ext/memcached
此块将克隆存储库，配置并安装扩展，然后在扩展自身后进行清理.
This block will clone the repository, configure and install the extension then clean up after it self.
您很有可能需要安装到软件包中以构建扩展，我们可以通过以下操作添加和删除它们:
It is most likely that you need to install to packages to build the extension, we can add and remove them by doing:
ENV MEMCACHED_DEPS zlib-dev libmemcached-dev cyrus-sasl-dev git
RUN set -xe \
&& apk add --no-cache libmemcached-libs zlib \
&& apk add --no-cache \
--virtual .memcached-deps \
$MEMCACHED_DEPS \
&& git clone -b php7 https://github.com/php-memcached-dev/php-memcached /usr/src/php/ext/memcached \
&& docker-php-ext-configure /usr/src/php/ext/memcached \
--disable-memcached-sasl \
&& docker-php-ext-install /usr/src/php/ext/memcached \
&& rm -rf /usr/src/php/ext/memcached \
&& apk del .memcached-deps
更新2017年5月17日
memcached现在已添加到php7的官方pecl库中(v3-> php7/7.1，v2-> php5)
memcached has been added to the official pecl libraries for php7 now (v3 -> php7/7.1, v2 -> php5)
这使安装有些不同
FROM php:7.0-alpine
ENV MEMCACHED_DEPS zlib-dev libmemcached-dev cyrus-sasl-dev
RUN apk add --no-cache --update libmemcached-libs zlib
RUN set -xe \
&& apk add --no-cache --update --virtual .phpize-deps $PHPIZE_DEPS \
&& apk add --no-cache --update --virtual .memcached-deps $MEMCACHED_DEPS \
&& pecl install memcached \
&& echo "extension=memcached.so" > /usr/local/etc/php/conf.d/20_memcached.ini \
&& rm -rf /usr/share/php7 \
&& rm -rf /tmp/* \
&& apk del .memcached-deps .phpize-deps
