Docker不安装PHP模块

Why are the modules not loaded?

This is my Dockerfile:

FROM php:5.6-apache

# Install PHP extensions and PECL modules.
RUN buildDeps=" \
        libbz2-dev \
        libmemcached-dev \
        libmysqlclient-dev \
        libsasl2-dev \
    " \
    runtimeDeps=" \
        curl \
        git \

        libldap2-dev \
        libmcrypt-dev \

    " \
    && apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y $buildDeps $runtimeDeps \
    && docker-php-ext-install bcmath bz2 calendar iconv intl mbstring mcrypt mysql 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 \
    && docker-php-ext-configure ldap --with-libdir=lib/x86_64-linux-gnu/ \
    && docker-php-ext-install ldap \
    && docker-php-ext-install exif \
    && pecl install memcached-2.2.0 redis \
    && docker-php-ext-enable memcached.so redis.so \
    && apt-get purge -y --auto-remove $buildDeps \
    && rm -r /var/lib/apt/lists/* \
    && a2enmod rewrite

RUN a2enmod rewrite
RUN usermod -u 1000 www-data
RUN usermod -G staff www-data

And this is the output from php -m:

[Zend Modules]

For example, there is no calendar extension, but it is defined in the Dockerfile itself. Also, exif doesn't appear in the list. Whats wrong here?

Solution was, that the php.ini hasn't been updated accordingly.

...
extension=gd.so
extension=calendar.so
extension=exif.so
extension=xdebug.so
extension=soap.so
extension=opcache.so
...

Now it works.

You can add a command in the Dockerfile to activate the extension after building. For example, to enable the calendar extension add:

RUN php5enmod calendar
