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. ----------------------------------------------------------------------  Build complete. Don't forget to run 'make test'.

This is my docker-compose.yml:

phlaconapp:     hostname: phaclonapp     dockerfile: Dockerfile     build: ./     ports:         - "1080:80"         - "1043:433"     environment:         TERM: xterm-color         ENVIRONMENT: dev     volumes:         - ./:/var/www/html/     links:         - mysql mysql:     image: mysql:5.6     volumes:         - ./docker/mysql.d:/etc/mysql/conf.d     ports: ["3306:3306"]     environment:         MYSQL_ROOT_PASSWORD: 'root' 

This is my Dockerfile:

FROM php:5.6-apache  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
