Cannot use mongodb (docker) with Symfony 3

Question

I am having some issue integrating mongodb with Symfony 3.1.2. I use the DoctrineMongoDBBundle.

Everything is okay up to the 'Persisting Objects to MongoDB' stage. When I add the lines :

$dm = $this->get('doctrine_mongodb')->getManager();
$dm->persist($product);
$dm->flush();

nothing happens to my remote database and I get the error message:

Attempted to load class "MongoId" from the global namespace. Did you forget a "use" statement?

I use docker beta on Mac. My docker-compose.yml :

version: '2'
services:
    application_ad:
        image: busybox
        volumes:
            - ./:/var/www/html
            - ./docker/nginx/conf.d/ad.conf:/etc/nginx/conf.d/default.conf
        entrypoint: "tail -f /dev/null"
    php_ad:
        build: ./docker/php-fpm
        links:
            - db
        volumes_from:
            - application_ad
    web_ad:
        build: ./docker/nginx
        ports:
            - "8089:80"
        links:
            - php_ad
        volumes_from:
            - application_ad
    db:
      image: mongo:3.2.7
      volumes:
        - ./mongo-data:/data/db
      ports:
        - "27017:27017"

And the php-fpm file :

PHPInfo() :

Maybe a docker problem ? Or a Symfony problem .

I am using PHP 7 with mongodb and using symfony and docker too. The only problem I have is the php-extension I needed to install is mongodb instead of mongo. After I install mongodb extension, everything works fine.

And here is my composer require:

"require": {
    "doctrine/mongodb-odm": "^1.1.0",
    "doctrine/mongodb-odm-bundle": "^3.1.0",
    "alcaeus/mongo-php-adapter": "^1.0.0",
    "ext-mongo": "*"
}

If it still fails when composer install, add this line below your composer require

"provide": {
    "ext-mongo": "1.6.13"
}

Hope it helps

Thanks. I updated my composer.json with your repository version. But I have some problems. First I had to add some dependencies : "mongodb/mongodb": "^1.0.0", "alcaeus/mongo-php-adapter": "^1.0", "ext-mongo": "*". But I have still problems : mongodb/mongodb 1.0.2 requires ext-mongodb ^1.1.0 -> the requested PHP extension mongodb is missing from your system.. Mongodb is not install in my mac. Only with docker.

I have updated my answer. First are you running composer install outside docker ? Actually you have to run composer install inside docker because the required depedencies are installed in docker.
