一.前言
公司php项目准备迁入docker，kubernetes进行管理，本文将介绍如何制作镜像，如何安装php扩展。
官方文档：https://hub.docker.com/_/php
二.Dockerfile
1.安装依赖
apk update &&apk add --no-cache autoconf gcc g++ libtool \ make libmemcached zlib libmemcached-dev libpng \ libpng-dev freetype-dev libjpeg-turbo-dev gettext-dev libmcrypt-dev\
2.安装gd库
gettext sockets pdo_mysql mysqli 同样的方式安装
docker-php-ext-configure gd \ --with-freetype-dir=/usr/include/ \ --with-jpeg-dir=/usr/include/ \ --with-png-dir=/usr/include/ \ docker-php-ext-install -j$(nproc) gd gettext sockets pdo_mysql mysqli
3.安装redis扩展
swoole mcrypt redis memcached 用pecl 安装,可指定版本号
pecl install mcrypt pecl install igbinary pecl install swoole-4.4.17 pecl install redis-5.2.1 pecl install memcached docker-php-ext-enable memcached igbinary swoole redis memcached
