Amazon S3 + Fog warning: connecting to the matching region will be more performant

I get the following warning while querying Amazon S3 via the Fog gem:

[WARNING] fog: followed redirect to my-bucket.s3-external-3.amazonaws.com, connecting to the matching region will be more performant

How exactly do I "connect to the matching region"?

Solution

  • Set the :region option in the Fog connection parameters to the name of the region in which your bucket exists.

    For example, I have a bucket called "bucket-a" in region "eu-west-1" and my s3 key and secret are in variables s3_key and s3_secret respectively.

    I can connect to this region directly by opening my Fog connection as follows:

    s3 = Fog::Storage.new(provider: 'AWS', aws_access_key_id: s3_key, aws_secret_access_key: s3_secret, region: 'eu-west-1')

    And now when I list the contents, no region warning is issued:

    s3.directories.get('bucket-a').files

    If you want to do this for all your buckets, rather than on a bucket-by-bucket basis you can set the following:

    Fog::Storage::AWS::DEFAULT_REGION = 'eu-west-1'
