Install Gearman Extension for PHP 7 via Docker.md

Assuming you are using the official PHP Docker image...

# ---------------------------------------------------------------
# PHP Extension: Gearman
# Download Gearman PECL extension for Gearman supporting PHP 7
RUN apt-get -y --allow-unauthenticated install \
    libgearman-dev
RUN cd /tmp \
    && git clone https://github.com/wcgallego/pecl-gearman.git \
    && cd pecl-gearman \
    && git checkout gearman-2.0.3 \
    && phpize \
    && ./configure \
    && make -j$(nproc) \
    && make install \
    && rm -r /tmp/pecl-gearman \
    && docker-php-ext-enable gearman

I updated this one a little:

RUN apt-get -y --allow-unauthenticated install libgearman-dev wget unzip \
    && cd /tmp \
    && wget https://github.com/wcgallego/pecl-gearman/archive/gearman-2.0.3.zip \
    && unzip gearman-2.0.3.zip \
    && mv pecl-gearman-gearman-2.0.3 pecl-gearman \
    && cd pecl-gearman \
    && phpize \
    && ./configure \
    && make -j$(nproc) \
    && make install \
    && cd / \
    && rm /tmp/gearman-2.0.3.zip \
    && rm -r /tmp/pecl-gearman \
    && docker-php-ext-enable gearman

@williamwa Thanks!

And if anyone interested, here's some shorter version without extra dependencies (e.g. wget, unzip) and with fewer FS-operations:

ENV GEARMAN_VERSION=2.0.3
RUN set -xe \
    ; apt-get -y install libgearman-dev \
    ; TMPDIR=$(mktemp -d) \
    ; cd $TMPDIR \
    ; curl -L https://github.com/wcgallego/pecl-gearman/archive/gearman-${GEARMAN_VERSION}.tar.gz \
    | tar xzv --strip 1 \
    ; phpize \
    ; ./configure \
    ; make -j$(nproc) \
    ; make install \
    ; cd - \
    ; rm -r $TMPDIR \
    ; docker-php-ext-enable gearman

Note the version can be picked from available releases.

For php 7.4 this is not working. Only for php 7.3. Has someone handled to install it on php 7.4?

I recently updated my install-php-extensions script; it now supports installing the gearman PHP extension (as well as 92 other PHP extensions) with a single line:

install-php-extensions gearman
