How can I avoid specifying ACLs when uploading files to S3?

[emuesuenu]

I am trying to upload a file to an S3 Bucket.
We are using fog-aws as the storage engine,
The object ACL setting for the bucket is disabled.

In this state, it is not possible to specify ACLs when uploading files,
I would like fog-aws to work without setting the x-amz-acl header.

CarrierWave's default implementation is to set some value regardless of the fog_public specification.

carrierwave/lib/carrierwave/storage/fog.rb

Lines 512 to 521 in 1531a67

	def acl_header
	case fog_provider
	when 'AWS'
	{ 'x-amz-acl' => @uploader.fog_public ? 'public-read' : 'private' }
	when "Google"
	@uploader.fog_public ? { destination_predefined_acl: "publicRead" } : {}
	else
	{}
	end
	end

How can I work around this?
I tried overriding acl_header when inheriting from CarrierWave::Uploader::Base, but it did not work as expected.

Setting

CarrierWave.configure do |config|
  config.fog_attributes = { 'x-amz-acl' => 'bucket-owner-full-control' }
end

should work, could you check? @emuesuenu @jalkoby @stormsilver

When ACLs are disabled on the bucket, S3 will throw an error for any request that specifies an ACL regardless of what the ACL is.

That's not correct, according to the AWS documentation:

https://docs.aws.amazon.com/AmazonS3/latest/userguide/about-object-ownership.html

After you disable ACLs, your bucket accepts only PUT requests that do not specify an ACL or PUT requests with bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL

It's working for me and I want you to actually use that configuration with your app.
