How to install php-redis extension using the official PHP Docker image approach?
PhpRedisDockerDockerfilePhp Problem Overview
I want to build my PHP-FPM image with php-redis extension based on the official PHP Docker image, for example, using this Dockerfile: php:5.6-fpm.
The docs say that I can install extensions this way, installing dependencies for extensions manually:
FROM php:5.6-fpm
# Install modules (iconv, mcrypt and gd extensions)
RUN apt-get update && apt-get install -y \
libfreetype6-dev \
libjpeg62-turbo-dev \
libmcrypt-dev \
libpng12-dev \
&& docker-php-ext-install iconv mcrypt \
&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
&& docker-php-ext-install gd
CMD ["php-fpm"]
Without Docker I installed it with apt-get install php5-redis. But how can I install it using the approach above?

Redis is not an extension that is included in “php-src”, therefore you cannot use docker-php-ext-install. Use PECL:
RUN pecl install -o -f redis \
&& rm -rf /tmp/pear \
&& docker-php-ext-enable redis
On alpine php 7.3.5 we can use:
RUN apk add --no-cache pcre-dev $PHPIZE_DEPS \
&& pecl install redis \
&& docker-php-ext-enable redis.so

My opinion, the easiest way is:
RUN pecl install redis && docker-php-ext-enable redis
;)
Solution 3 - Php
Slightly revised version of starikovs and skyred answers for the current PHP 7 version of the docker image (tested on php:7.0.8-fpm-alpine and php:7.0.8-alpine).
Uses the newly released 3.0 version (June 2016) for PHP 7.
ENV PHPREDIS_VERSION 3.0.0
RUN mkdir -p /usr/src/php/ext/redis \
&& curl -L https://github.com/phpredis/phpredis/archive/$PHPREDIS_VERSION.tar.gz | tar xvz -C /usr/src/php/ext/redis --strip 1 \
&& echo 'redis' >> /usr/src/php-available-exts \
&& docker-php-ext-install redis
Solution 4 - Php
I've found two ways to install php-redis extension for official php-fpm Docker image. Here they are:
The first way is to compile redis from sources and install.
RUN curl -L -o /tmp/redis.tar.gz https://github.com/phpredis/phpredis/archive/2.2.7.tar.gz \
&& tar xfz /tmp/redis.tar.gz \
&& rm -r /tmp/redis.tar.gz \
&& mv phpredis-2.2.7 /usr/src/php/ext/redis \
&& docker-php-ext-install redis
docker-php-ext-install script is included in php-fpm image and can compile extensions and install them.
The second way you can do it is with PECL.
As TimWolla answered, you can do it with PECL, but in my case, PECL isn't installed by default.
RUN pecl install -o -f redis \
&& rm -rf /tmp/pear \
&& echo "extension=redis.so" > /usr/local/etc/php/conf.d/redis.ini
Solution 5 - Php
Based on @starikovs answer. I added a variable for docker style.
# install phpredis extension
ENV PHPREDIS_VERSION 2.2.7
RUN curl -L -o /tmp/redis.tar.gz https://github.com/phpredis/phpredis/archive/$PHPREDIS_VERSION.tar.gz \
&& tar xfz /tmp/redis.tar.gz \
&& rm -r /tmp/redis.tar.gz \
&& mv phpredis-$PHPREDIS_VERSION /usr/src/php/ext/redis \
&& docker-php-ext-install redis
Solution 6 - Php
If you want to use redis as session handler;
RUN { \
echo 'session.save_handler = redis'; \
echo 'session.save_path = tcp://redis:6379'; \
} >> /usr/local/etc/php/conf.d/docker-php-ext-redis.ini
If you want to use redis extension with PHP 7 in 2015 (borrowed from skyred's answer);
ENV PHPREDIS_VERSION php7
RUN curl -L -o /tmp/redis.tar.gz https://github.com/phpredis/phpredis/archive/$PHPREDIS_VERSION.tar.gz \
&& tar xfz /tmp/redis.tar.gz \
&& rm -r /tmp/redis.tar.gz \
&& mv phpredis-$PHPREDIS_VERSION /usr/src/php/ext/redis \
&& docker-php-ext-install redis
Solution 7 - Php
This works for alpine images:
RUN set -xe \
&& apk add --no-cache --update --virtual .phpize-deps $PHPIZE_DEPS \
&& pecl install -o -f redis \
&& echo "extension=redis.so" > /usr/local/etc/php/conf.d/redis.ini \
&& rm -rf /usr/share/php \
&& rm -rf /tmp/* \
&& apk del .phpize-deps
Edit: Added missing backslash
Solution 8 - Php
Tried few ways. On alpine php 7.3.5 we can use:
RUN apk add --no-cache pcre-dev $PHPIZE_DEPS \
&& pecl install redis \
&& docker-php-ext-enable redis.so
Solution 9 - Php
I'm using combination of PECL and PHP official docker extension script
RUN pecl bundle -d /usr/src/php/ext redis \
&& rm /usr/src/php/ext/redis-*.tgz \
&& docker-php-ext-install redis
For PHP7 you need to wait for official redis pecl release or use git:
RUN apt-get update \
&& apt-get install git -y -q \
&& git clone -b php7 https://github.com/phpredis/phpredis.git /usr/src/php/ext/redis \
&& docker-php-ext-install redis
Solution 10 - Php
Slightly revised version of starikovs and skyred answers for current version of the docker image. Tested on php:5-fpm-alpine
# install phpredis extension
ENV PHPREDIS_VERSION 2.2.8
ADD https://github.com/phpredis/phpredis/archive/$PHPREDIS_VERSION.tar.gz /tmp/redis.tar.gz
RUN tar xzf /tmp/redis.tar.gz -C /tmp \
&& mkdir -p /usr/src/php/ext \
&& mv /tmp/phpredis-$PHPREDIS_VERSION /usr/src/php/ext/redis \
&& echo 'redis' >> /usr/src/php-available-exts \
&& docker-php-ext-install redis \
&& rm -rf /usr/src/php/ext/redis
Solution 11 - Php
In your Dockerfile you can clone the repo and install it with:
RUN git clone https://github.com/phpredis/phpredis.git /tmp/phpredis \
&& cd /tmp/phpredis \
&& git checkout -b 3.1.2 \ ## or the release you need #
&& phpize \
&& ./configure \
&& make \
&& make install
Solution 12 - Php
For image php:7.2-fpm-alpine.
RUN apk add autoconf gcc g++ make && pecl install redis && docker-php-ext-enable redis
You may need to update before
apk --update upgrade
