List S3 Buckets from a specific region

I am using AWS Ruby SDK v2 to get S3 Bucket names. Is there a way to get S3 buckets from a specific region?

The way I do it now:

buckets = s3_client.list_buckets.buckets.map(&:name)
buckets.select { |name| s3_client.get_bucket_location(:bucket => name).location_constraint == @region }

This gets all the buckets I have in buckets. Then I filter ones that are from region I specified with @region.

I would like to be able to do this with making only one request through AWS SDK. Is this possible somehow?

Well I solved this with the PHP SDK using client->getBucketLocation(). With the multiRegion client you can just use the 'LocationConstraint', with the standard single region client I can handle this by catching the Exception for non-defined Regions.

That said, with the RubySDK (which I'm less familiar with) Amazon suggests you use this (as an example):

require 'aws-sdk-s3'  # v2: require 'aws-sdk'

region = 'us-west-2'
s3 = Aws::S3::Resource.new(region: region)

s3.buckets.limit(50).each do |b|
  if s3.client.get_bucket_location(bucket: b.name).location_constraint == region
    puts "#{b.name}"
  end
end

More information can be found here: https://docs.aws.amazon.com/sdk-for-ruby/v3/developer-guide/s3-example-get-buckets-in-region.html#aws-ruby-sdk-s3-example-get-buckets-in-region
