How to install php-redis extension using the official PHP Docker image approach?

Question

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

Answer 1

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
