新浪云Apache PHP基础镜像

该镜像基于PHP官方Docker镜像构建，安装了大部分常用的扩展，作为新浪云PHP环境的基础镜像

安装其他扩展

由于继承了官方PHPDocker镜像，安装扩展可以参考官方：

PHP Core Extensions

For example, if you want to have a PHP-FPM image with iconv, mcrypt and gd extensions, you can inherit the base image that you like, and write your own Dockerfile like this:

FROM sinacloud/docker-apache-php:latest
RUN apt-get update && apt-get install -y \
		libfreetype6-dev \
		libjpeg62-turbo-dev \
		libmcrypt-dev \
		libpng-dev \
	&& docker-php-ext-install -j$(nproc) iconv mcrypt \
	&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
	&& docker-php-ext-install -j$(nproc) gd

Remember, you must install dependencies for your extensions manually. If an extension needs custom configure arguments, you can use the docker-php-ext-configure script like this example. There is no need to run docker-php-source manually in this case, since that is handled by the configure and install scripts.

See "Dockerizing Compiled Software" for a description of the technique Tianon uses for determining the necessary build-time dependencies for any bit of software (which applies directly to compiling PHP extensions).

PECL extensions

Some extensions are not provided with the PHP source, but are instead available through PECL. To install a PECL extension, use pecl install to download and compile it, then use docker-php-ext-enable to enable it:

FROM sinacloud/docker-apache-php:latest
RUN pecl install redis-3.1.0 \
	&& pecl install xdebug-2.5.0 \
	&& docker-php-ext-enable redis xdebug

FROM sinacloud/docker-apache-php:latest
RUN apt-get update && apt-get install -y libmemcached-dev zlib1g-dev \
	&& pecl install memcached-2.2.0 \
	&& docker-php-ext-enable memcached

Other extensions

Some extensions are not provided via either Core or PECL; these can be installed too, although the process is less automated:

FROM sinacloud/docker-apache-php:latest
RUN curl -fsSL 'https://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz' -o xcache.tar.gz \
	&& mkdir -p xcache \
	&& tar -xf xcache.tar.gz -C xcache --strip-components=1 \
	&& rm xcache.tar.gz \
	&& ( \
		cd xcache \
		&& phpize \
		&& ./configure --enable-xcache \
		&& make -j$(nproc) \
		&& make install \
	) \
	&& rm -r xcache \
	&& docker-php-ext-enable xcache

The docker-php-ext-* scripts can accept an arbitrary path, but it must be absolute (to disambiguate from built-in extension names), so the above example could also be written as the following:

FROM sinacloud/docker-apache-php:latest
RUN curl -fsSL 'https://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz' -o xcache.tar.gz \
	&& mkdir -p /tmp/xcache \
	&& tar -xf xcache.tar.gz -C /tmp/xcache --strip-components=1 \
	&& rm xcache.tar.gz \
	&& docker-php-ext-configure /tmp/xcache --enable-xcache \
	&& docker-php-ext-install /tmp/xcache \
	&& rm -r /tmp/xcache
