How to install extension for php via docker-php-ext-install? - php

Question

In order to resolve an issue, I am now trying install the mysql pdo via
docker-php-ext-install
as pointed out in the README of the php image.
Yet my call fails stating:
Libraries have been installed in:
/usr/src/php/ext/mysqli/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

and running docker-compose build won't finish.

I had the same problem a while ago. I started a container and typed the ext-install command into this container. Once I found all the dependencies, I wrote them into the Dockerfile.
Example:
RUN apt-get update && apt-get install -y \
libmcrypt-dev \
&& docker-php-ext-install -j$(nproc) mcrypt
There is a dependency that libmcrypt-dev needed before you can run docker-php-ext-install mcrypt
I've checked my older Dockerfiles and found something which might help you
FROM php:5.6-apache
RUN apt-get update && apt-get install -y \
libfreetype6-dev \
libjpeg62-turbo-dev \
libmcrypt-dev \
libpng12-dev \
libicu-dev \
libxml2-dev \
vim \
wget \
unzip \
git \
&& docker-php-ext-install -j$(nproc) iconv intl xml soap mcrypt opcache pdo pdo_mysql mysqli mbstring \
&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
&& docker-php-ext-install -j$(nproc) gd
RUN a2enmod rewrite && mkdir /composer-setup && wget https://getcomposer.org/installer -P /composer-setup && php /composer-setup/installer --install-dir=/usr/bin && rm -Rf /composer-setup && curl -LsS https://symfony.com/installer -o /usr/local/bin/symfony && chmod a+x /usr/local/bin/symfony
# Create symlink for default conf
RUN ln -s /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-enabled/000-default.conf && mkdir /composer-setup && wget https://getcomposer.org/installer -P /composer-setup && php /composer-setup/installer --install-dir=/usr/bin && rm -Rf /composer-setup && curl -LsS https://symfony.com/installer -o /usr/local/bin/symfony && chmod a+x /usr/local/bin/symfony

RUN docker-php-ext-install mbstring pdo pdo_mysql \
That code can do install any extension you want in this case mysql pdp driver but the Dockerfile should have base of FROM php:7.1.8-apache

The 2019 way and probably the 2020 way of installing memcached to your Docker PHP container is the way described on https://hub.docker.com/_/php
FROM php:latest
RUN pecl install memcached \
&& docker-php-ext-enable memcached
FROM php:5.6-cli
RUN apt-get update && apt-get install -y libmemcached-dev zlib1g-dev \
&& pecl install memcached-2.2.0 \
&& docker-php-ext-enable memcached

Seems to be a bug in phpize (https://bugs.php.net/bug.php?id=53571).
I added the following to docker-php-ext-configure:
/usr/local/bin # diff -u docker-php-ext-configure.bak docker-php-ext-configure
--- docker-php-ext-configure.bak
+++ docker-php-ext-configure
## -54,5 +54,6 ##
set -x
cd "$ext"
+[[ ! -f "config.m4" && -f "config0.m4" ]] && mv config0.m4 config.m4
phpize
./configure "$#"

Alternatively, you can use this excellent helper to install the needed libs automatically for you.
https://github.com/mlocati/docker-php-extension-installer
You only need to list the extensions you want like this:
FROM php:8.2-fpm-alpine
ADD https://github.com/mlocati/docker-php-extension-installer/releases/latest/download/install-php-extensions /usr/local/bin/
RUN chmod +x /usr/local/bin/install-php-extensions; \
install-php-extensions mysqli mysqlnd pdo pdo_mysql zip
Take a look at its GitHub page to see all options available to use.
