AmazonS3Resolver
================

The AmazonS3Resolver requires the `aws-sdk-php`_ library. Open a command
console, enter your project directory and execute the following command to
download the latest stable version of this library:

.. code-block:: bash

    $ composer require aws/aws-sdk-php

This command requires you to have Composer installed globally, as explained
in the `installation chapter`_ of the Composer documentation.

Afterwards, you only need to configure some information regarding your AWS
account and the bucket.

.. code-block:: yaml

    parameters:
        amazon_s3.key: 'your-aws-key'
        amazon_s3.secret: 'your-aws-secret'
        amazon_s3.bucket: 'your-bucket.example.com'

Now you can set up the services required:

.. code-block:: yaml

    services:
        acme.amazon_s3:
            class: AmazonS3
            arguments:
                -
                    key: %amazon_s3.key%
                    secret: %amazon_s3.secret%
                    # more S3 specific options, see \AmazonS3::__construct()

        acme.imagine.cache.resolver.amazon_s3:
            class: Liip\ImagineBundle\Imagine\Cache\Resolver\AmazonS3Resolver
            arguments:
                - "@acme.amazon_s3"
                - "%amazon_s3.bucket%"
            tags:
                - { name: 'liip_imagine.cache.resolver', resolver: 'amazon_s3' }

Now you are ready to use the ``AmazonS3Resolver`` by configuring the bundle.
The following example will configure the resolver is default.

.. code-block:: yaml

    liip_imagine:
        cache: 'amazon_s3'

If you want to use other buckets for other images, simply alter the parameter
names and create additional services!

Object URL Options
------------------

In order to make use of the object URL options, you can simply add a call to the
service, to alter those options you need.

.. code-block:: yaml

    services:
        acme.imagine.cache.resolver.amazon_s3:
            class: Liip\ImagineBundle\Imagine\Cache\Resolver\AmazonS3Resolver
            arguments:
                - "@acme.amazon_s3"
                - "%amazon_s3.bucket%"
            calls:
                 # This calls $service->setObjectUrlOption('https', true);
                 - [ setObjectUrlOption, [ 'https', true ] ]
            tags:
                - { name: 'liip_imagine.cache.resolver', resolver: 'amazon_s3' }

You can also use the constructor of the resolver to directly inject multiple
options.

.. code-block:: yaml

    services:
        acme.imagine.cache.resolver.amazon_s3:
            class: Liip\ImagineBundle\Imagine\Cache\Resolver\AmazonS3Resolver
            arguments:
                - "@acme.amazon_s3"
                - "%amazon_s3.bucket%"
                - "public-read" # AmazonS3::ACL_PUBLIC (default)
                - { https: true, torrent: true }
            tags:
                - { name: 'liip_imagine.cache.resolver', resolver: 'amazon_s3' }
