使用Docker构建PHP7.4镜像,并添加redis，zip模块等

默认的官方php docker镜像是不带redis扩展的，甚至连gd、opcache、pdo_mysql等扩展也要自己配置。

修改镜像源文件，sources.list内容如下：

deb http://mirrors.aliyun.com/debian/ buster main contrib non-free
deb-src http://mirrors.aliyun.com/debian/ buster main contrib non-free
 
deb http://mirrors.aliyun.com/debian-security/ buster/updates main contrib non-free
deb-src http://mirrors.aliyun.com/debian-security/ buster/updates main contrib non-free
 
deb http://mirrors.aliyun.com/debian/ buster-updates main contrib non-free
deb-src http://mirrors.aliyun.com/debian/ buster-updates main contrib non-free
 
deb http://mirrors.aliyun.com/debian/ buster-backports main contrib non-free
deb-src http://mirrors.aliyun.com/debian/ buster-backports main contrib non-free

以下是Dockerfile文件内容：

FROM php:7.4-fpm

ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

COPY  sources.list /etc/apt/sources.list

RUN apt-get update && echo y| apt-get install \
    --no-install-recommends libfreetype6-dev libjpeg62-turbo-dev libpng-dev zlib1g=1:1.2.11.dfsg-1+deb10u2 zlib1g-dev libzip-dev \
    && rm -r /var/lib/apt/lists/* \
    && docker-php-ext-configure gd \
    && docker-php-ext-install -j$(nproc) gd opcache pdo_mysql gettext sockets zip
 
RUN pecl install redis \
    && docker-php-ext-enable redis

ENV COMPOSER_HOME /root/composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
ENV PATH $COMPOSER_HOME/vendor/bin:$PATH

构建镜像命令：

docker build -t new_php:7.4 .
