docker运行php网站程序

有一个以前的php网站程序须要迁移到K8S，简单调研了下。php

基础镜像

官方提供了诸如php:7.1-apache的基础镜像，可是确认必要的扩展，例如gd，固然官方提供了docker-php-ext-install命令，能够用来安装须要的扩展。可是每次构建都从新安装很是费时，最好的办法是构建一个包含必要扩展的基础镜像。html

FROM php:7.1-apache
ENV PORT 80
EXPOSE 80

RUN buildDeps=" \
        default-libmysqlclient-dev \
        libbz2-dev \
        libsasl2-dev \
    " \
    runtimeDeps=" \
        curl \
        git \
        libfreetype6-dev \
        libicu-dev \
        libjpeg-dev \
        libmcrypt-dev \
        libpng-dev \
        libpq-dev \
        libxml2-dev \
    " \
    sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list  \
    && apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y $buildDeps $runtimeDeps \
    && docker-php-ext-install bcmath bz2 calendar iconv intl mbstring mcrypt mysqli opcache pdo_mysql pdo_pgsql pgsql soap zip \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install gd \
    && apt-get purge -y --auto-remove $buildDeps \
    && rm -r /var/lib/apt/lists/* 

ENV PATH=$PATH:/root/composer/vendor/bin COMPOSER_ALLOW_SUPERUSER=1

而后构建基础镜像mysql

docker build -t common/php:7.1-apache .

PS：更多的php镜像，查看 https://github.com/chialab/docker-phpgit

使用基础镜像

Dockerfile应用刚构建好的基础镜像：github

FROM common/php:7.1-apache
ENV PORT 80
EXPOSE 80
COPY . /var/www/html
RUN usermod -u 1000 www-data; \
	a2enmod rewrite; \
	chown -R www-data:www-data /var/www/html

构建便可：sql

docker build -t common/zhifou:v0.0.12 .
