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
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
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
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
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/$PHPREDIS_VERSION.tar.gz | tar xvz -C /usr/src/php/ext/redis --strip 1 \
&& echo 'redis' >> /usr/src/php-available-exts \
&& docker-php-ext-install redis
Based on @starikovs answer. I added a variable for docker style.
# install phpredis extension
ENV PHPREDIS_VERSION 2.2.7
RUN curl -L -o /tmp/redis.tar.gz https://github.com/phpredis/phpredis/archive/$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
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
