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

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.

Don't forget to run 'make test'.

ERROR: Service 'phlaconapp' failed to build: The command '/bin/sh -c docker-php-ext-install mysqli mysqlnd pdo pdo_mysql zip' returned a non-zero code: 1

This is my docker-compose.yml :

    ports:
        - "1080:80"

    ports: ["3306:3306"]
    environment:

This is my Dockerfile :

RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" && \
    php -r "if (hash_file('SHA384', 'composer-setup.php') === '070854512ef404f16bac87071a6db9fd9721da1684cd4589b1196c3faf71b9a2682e2311b36a5079825e155ac7ce150d') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;" && \
    php composer-setup.php && \
    php -r "unlink('composer-setup.php');"


RUN apt-get update && \
    apt-get install vim git -y
RUN docker-php-ext-install mysqli mysqlnd pdo pdo_mysql zip 

RUN  cd /  && \
    git clone --depth=1 git://github.com/phalcon/cphalcon.git && \
    cd cphalcon/build && \
    ./install

RUN echo "extension=phalcon.so" > /usr/local/etc/php/conf.d/phalcon.ini
RUN a2enmod rewrite

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 \

在这种情况下，该代码可以安装您想要的任何扩展 mysql pdp 驱动程序，但 Dockerfile 应该具有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.
