Memcached support

[polds]

Wondering if anyone has gotten memcached (not memcache) to work? Trying to build in php:5.5.29-apache to get the php memcached module installed. I have tried the following to no avail. Any help is greatly appreciated.

Dockerfile 1

RUN apt-get update \
  && apt-get install -y php5-memcached

CMD ["apache2", "-DFOREGROUND"]

@polds I think you want to use "Dockerfile 2", but you need to install libz-dev to make configure happy.

[md5]

Actually, nevermind... I thought you were using docker-php-ext-install 😕

You need something like this:

FROM php:5.5.29-apache
RUN apt-get update && apt-get install -y libz-dev libmemcached-dev
RUN pecl install memcached

[polds]

@md5 thank you that was indeed it with the following modification (for future readers):

FROM php:5.5.29-apache
RUN apt-get update && apt-get install -y libz-dev libmemcached-dev
RUN pecl install memcached
RUN echo extension=memcached.so >> /usr/local/etc/php/conf.d/memcached.ini

[md5]

Thanks @polds.

That reminds me that @helderco once mentioned creating a docker-php-pecl-install script: #115 (comment)

[hairmare]

The smallest layer for the pecl install is probably the following:

RUN apt-get update \
  && apt-get install -y libmemcached11 libmemcachedutil2 build-essential libmemcached-dev libz-dev \
  && pecl install memcached \
  && echo extension=memcached.so >> /usr/local/etc/php/conf.d/memcached.ini \
  && apt-get remove -y build-essential libmemcached-dev libz-dev \
  && apt-get autoremove -y \
  && apt-get clean \
  && rm -rf /tmp/pear

[polds]

^ That worked as well.

[md5]

Thanks @hairmare I was being lazy since I don't tend to be as aggressive with the sizes of "normal" images.

I think you'll also want a rm -rf /var/lib/apt/lists/* in there as well since apt-get clean doesn't clean as much as it could.

I failed to get memcached to work on PHP7. Finally managed to do so using the following lines, using the php7 branch and building from source:

# Memcached
RUN apt-get install -y libmemcached-dev \
 && cd /tmp \
 && git clone -b php7 https://github.com/php-memcached-dev/php-memcached.git \
 && cd php-memcached \
 && phpize \
 && ./configure \
 && make \
 && echo "extension=/tmp/php-memcached/modules/memcached.so" > /usr/local/etc/php/conf.d/memcached.ini

Is there any better way?

[paolomainardi]

@roelvanduijnhoven for PHP7 ì'm doing this:

  git clone https://github.com/php-memcached-dev/php-memcached /usr/src/php/ext/memcached \
  && cd /usr/src/php/ext/memcached && git checkout -b php7 origin/php7 \
  && docker-php-ext-configure memcached \
  && docker-php-ext-install memcached 

[roelvanduijnhoven]

Thanks @paolomainardi, looks a lot easier. I realise now how the bundled docker-php-ext.. scripts work.

[paolomainardi]

@roelvanduijnhoven you're welcome

[skyred]

Thank you all. I further shortened #132 (comment) a little bit. Now, I am using this config in my image for Drupal https://github.com/INsReady/php-fpm-for-cms/blob/master/7.0/Dockerfile#L11

With last version php:7.0-fpm stop working

[yosifkit]

@vitalyzhakov, I think that is related to #266.

[roelvanduijnhoven]

Did anyone manage to fix this problem? I am reading through #266 but have no clue if and how I should solve this..

[vitalyzhakov]

@roelvanduijnhoven ,

This code works for me under php 7.0.8-fpm

# install memcached
    && apt-get -y install libmemcached11 libmemcachedutil2 libmemcached-dev \
    && git clone --branch php7 https://github.com/php-memcached-dev/php-memcached \
    && cd php-memcached \
    && phpize \
    && ./configure \
    && make \
    && echo "extension=/var/www/html/php-memcached/modules/memcached.so" > /usr/local/etc/php/conf.d/memcached.ini 

[roelvanduijnhoven]

Thanks! ❤️

[rasteiner]

This may be obvious, but for someone (like me) it's not.

Notice that the above snippet puts the memcached library into /var/www/html/. When you create a volume from a host directory and mount that into /var/www/html, docker "overwrites" that path and your module "disappears".

So if you want to mount a volume into /var/www/html, change the snippet to clone the repo into another directory and adjust the corresponding line that creates the php config file.

Something like this works for me:

RUN apt-get -y install libmemcached11 libmemcachedutil2 libmemcached-dev \
    && cd /usr/local/share \
    && git clone --branch php7 https://github.com/php-memcached-dev/php-memcached \
    && cd php-memcached \
    && phpize \
    && ./configure \
    && make \
    && echo "extension=/usr/local/share/php-memcached/modules/memcached.so" > /usr/local/etc/php/conf.d/memcached.ini

[c0deright]

Please do it the right way: use the docker-php-* scripts and cleanup afterwards.

The best practice should look something like this:

FROM php:7.0-fpm

RUN apt-get update \
        && buildDeps=" \
                git \
                libmemcached-dev \
                zlib1g-dev \
        " \
        && doNotUninstall=" \
                libmemcached11 \
                libmemcachedutil2 \
        " \
        && apt-get install -y $buildDeps --no-install-recommends \
        && rm -r /var/lib/apt/lists/* \
        \
        && docker-php-source extract \
        && git clone --branch php7 https://github.com/php-memcached-dev/php-memcached /usr/src/php/ext/memcached/ \
        && docker-php-ext-install memcached \
        \
        && docker-php-source delete \
        && apt-mark manual $doNotUninstall \
        && apt-get purge -y --auto-remove -o APT::AutoRemove::RecommendsImportant=false $buildDeps

This way you use docker-php-source, don't have to create an ini file, call phpize and make yourself and most important this way you remove not needed -dev packages and all their dependencies (except for runtime dependencies in $doNotUninstall) to save disk-space.

@adminblogger nice! Thx!

If your favor... Tell me pls... Where can i find runtime dependencies for another extensional?
I can mark to delete git, zlib1g-dev, but someone once?
Using on install

• libfreetype6-dev libjpeg62-turbo-dev libmcrypt-dev libpng12-dev - for gd
• zlib1g-dev libicu-dev - for intl
• libpq-dev - for pdo_pgsql
• libmagickwand-dev - for imagick

FROM php:7.0.11-fpm
RUN apt-get update && apt-get install -y \
        git \

    && pecl install imagick \
    && docker-php-ext-enable imagick

For anyone who finds this because their Dockerfile has begun to fail while trying "pecl install memcached" (with the error "pecl/memcached requires PHP (version >= 7.0.0), installed version is [5.6.something]", on 02/08/17 the pecl memcached package version 3.0 was released, requiring php 7.0 or higher.

To continue using memcached with php 5.6.x, update your Dockerfile to use version 2.2.0 of the memcached package:

pecl install memcached-2.2.0

instead of

pecl install memcached

The relevant section of my Dockerfile, as a result, is:

RUN apt-get -y install libz-dev libmemcached-dev libmemcached11 libmemcachedutil2 build-essential \
&& pecl install memcached-2.2.0 \
&& echo extension=memcached.so >> /usr/local/etc/php/conf.d/memcached.ini \
&& apt-get remove -y build-essential libmemcached-dev libz-dev \
&& apt-get autoremove -y \
&& apt-get clean \
&& rm -rf /tmp/pear
