AwsS3 + LiipImagineBundle + KnpGaufretteBundle + Symfony2.7+

If I could spare anyone even a fraction of the time it took me to configure this properly I can only imagine the time saved, given the last two days of head pounding I’ve gone through to finally make this correctly work with the latest AWS SDK (v3.2.5).

So all that under the bridge, here’s a final config to have your images, and any (all) associated filters cached in your S3 buckets.

app/config/parameters.yml

parameters:
    # You probably don't want to use "latest" in a production environment...
    aws_sdk_version: latest 
    aws_access_key_id: YOUR_AWS_ACCESS_KEY_ID
    aws_secret_access_key: YOUR_AWS_SECRET_ACCESS_KEY
    aws_s3_region: us-east-1
    aws_bucket_name: YOUR_BUCKET_NAME
    # This isn't required for this config, but I use it everywhere, so..
    aws_s3_base_url: 'https://s3.amazonaws.com'
