PHP7无法在Alpine docker容器上加载memcached和redis

I'm trying to create a Docker image based on Alpine Linux which will run PHP 7.1 (apk add php7=7.1.9-r0) with some modules installed (memcached, mongodb, oauth, openssl and redis).

I install the modules through PECL like this:

RUN yes | pecl install \
  igbinary \
  redis-3.1.4 \
  oauth-2.0.2 \
  memcached-3.0.4 \
  mongodb-1.3.3

Then add each of them to php.ini.

RUN for EXT in \
    igbinary \
    memcached \
    mongodb \
    oauth \
    openssl \
    redis; \
  do \
    echo "extension=${EXT}.so" >> /etc/php7/php.ini; \
  done

Most modules install correctly, but memcached and redis don't want to play along:

# php -v
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php7/modules/memcached.so' - Error relocating /usr/lib/php7/modules/memcached.so: php_session_create_id: symbol not found in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php7/modules/redis.so' - Error relocating /usr/lib/php7/modules/redis.so: php_session_register_module: symbol not found in Unknown on line 0
PHP Warning:  Module 'openssl' already loaded in Unknown on line 0
PHP Warning:  Cannot load module 'mongodb' because required module 'json' is not loaded in Unknown on line 0
PHP 7.1.9 (cli) (built: Oct  2 2017 20:51:54) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies

I've also tried from source:

RUN git clone https://github.com/php-memcached-dev/php-memcached
RUN cd php-memcached \
  && git checkout php7 \
  && git pull \
  && /usr/bin/phpize \
  && ./configure --with-php-config=/usr/bin/php-config \
  && make \
  && make install

This however gives me the same result. I've done some searching and apparently there might be some related problem of glibc on Alpine (example thread) but I'm not quite sure this is the same issue as the error output is a bit confusing.

Is there anything I'm overlooking as to how these modules should be installed to work with PHP 7.1 on Alpine Linux?

    All of these extensions are available in Alpine repositories, so why are you making your life harder and installs them directly from PECL? Install them simply using apk.

    Note that these packages are in Alpine v3.7 (the latest stable release), I haven’t checked if they are available also in older releases.

    These packages, of course, installs config files with extension=<ext>.so, so don’t add it manually to php.ini.


    apk add php7=7.1.9-r0

    Why do you specify exact version? This will fail once we update the package (e.g. with security patches), because only the latest version of packages is available in the repositories. We backport only security fixes and bugfixes (i.e. patch versions) into stable releases, so there will not be 7.2.x in v3.6 or v3.7.
