So I am attempting to build a Silex 2 application; using docker service containerization as the ENV control system. However, when accessing the resource the return is a PDO Exception 'driver not found'.
docker-compose.yml
# program code
code:
build: docker/code
# env_file: .env
ports:
- "80:8080"
volumes:
- ./code:/code
# database
db:
image: mysql:latest
volumes:
- /var/lib/mysql
ports:
- "3306:3306"
environment:
MYSQL_ROOT_PASSWORD: root
MYSQL_DATABASE: app_db
MYSQL_USER: app_db_user
MYSQL_PASSWORD: app_db_pass
code Dockerfile
FROM php:7
WORKDIR /code
# install curl and php
RUN apt-get update -y
RUN apt-get install git zip -y
# install composer & app deps; then remove
RUN curl -sS https://getcomposer.org/installer | php
RUN mv composer.phar /usr/local/bin/composer
EXPOSE 80
CMD ["php", "-S", "0.0.0.0:80"]
server logic
<?php
# silex micro framework basic entry script
// web/index.php
require_once __DIR__.'/vendor/autoload.php';
require_once __DIR__.'/common/env.php';
$app = new Silex\Application();
$app['debug'] = true;
$app->register(new Silex\Provider\DoctrineServiceProvider(), [
'db.options' => [
'driver' => 'pdo_mysql',
'dbname' => 'app_db',
'host' => '172.17.0.2',
'user' => 'app_db_user',
'password' => 'app_db_pass',
'charset' => 'utf8mb4',
'port' => '3306',
]
]);
$app->get('/', function () use ($app) {
$sql = 'SELECT * FROM test WHERE id = 1';
$data = $app['db']->fetchAssoc($sql);
return json_encode($data);
});
$app->run();
The Error:
Whoops, looks like something went wrong.

As a side note I'd like to keep the server
service as abstracted as possible as the server may be one of any number of options (built in, apache, nginx, etc).
I has to be something simple Im over looking, but what?
Fixed it:
Noticed
RUN docker-php-ext-install pdo pdo_mysql
. Apparently installing php extensions in the php docker container requires using the built indocker-php-ext-install
anddocker-php-ext-configure
scripts that are provided with the machine.
