How can I install xcache?

[ir-fuel]

I tried creating a Dockerfile based on php:5.6-apache

I added

RUN apt-get -y install php5-xcache

but when opening a php file containing phpinfo() there is no mention of xcache at all.

What am I doing wrong?

nope

yes there is a problem, Try to install it from source

[ir-fuel]

why should that make a difference?
RUN apt-get -y install php5-xcache

executes without errors. It's just that it doesn't seem to startup with php/apache somehow.

While trying to figure out how to get xcache enabled easily, I found and fixed a bug in our enable script (#172).

So, once that PR merges, this will be as easy as something like this: (adjusting versions and paths as appropriate or desired)

FROM php:5.6-apache
RUN curl -fsSL 'https://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz' -o /tmp/xcache.tar.gz \
    && mkdir -p /tmp/xcache \
    && tar -xf /tmp/xcache.tar.gz -C /tmp/xcache --strip-components=1 \
    && cd /tmp/xcache \
    && phpize \
    && ./configure --enable-xcache \
    && make -j$(nproc) \
    && make install \
    && docker-php-ext-enable xcache \
    && cd / \
    && rm -rf /tmp/xcache*
