Pecl does not work on php:7.0-fpm

[ihorsamusenko]

I have pretty simple dockerfile

FROM php:7.0-fpm
RUN apt-get clean
&& apt-get update && pecl install memeched

But unfortunately I am getting error:

pecl/memcached requires PHP (version >= 5.2.0, version <= 6.0.0, excluded versions: 6.0.0), installed version is 7.0.12

Why is that?

memcached does not have a php7 release yet.

As an alternative you can use the php7 branch from the git repo.

FROM php:7.0-fpm

RUN apt-get update \
  && apt-get install -y \
     libmemcached11 \
     libmemcachedutil2 \
     build-essential \
     libmemcached-dev \
     libz-dev \
     git \
  && git clone -b php7 https://github.com/php-memcached-dev/php-memcached.git /usr/src/php/ext/memcached \
  && cd /usr/src/php/ext/memcached \
  && phpize \
  && ./configure \
  && make all \
  && docker-php-ext-install memcached \
  && docker-php-ext-enable memcached 

The comments on the issue I linked do seem to indicate that you might experience some issues during use.

Memcached now has stable PHP 7 release, so now it can be included in docker-php-ext-install, can not?

[iBobik]

This will install stable memcached and igbinary (for more effective serialization) extensions:

RUN apt-get update && apt-get install -y libmemcached \
	&& apt-get clean \
	&& yes '' | pecl install igbinary memcached \
	&& pecl clear-cache \
	&& docker-php-ext-enable igbinary.so memcached.so

Confirmed working with recent versions of the memcached PECL extension! 👍
