You can setup carrierwave config in separate uploader. like this.

using gem 'aws-sdk', '~> 2.10' gem 'carrierwave-aws', '~> 1.1'

    class BusinessDocumentUploader < CarrierWave::Uploader::Base

    def initialize(*)
      super



      CarrierWave.configure do |config|
      config.storage    = :aws
      config.aws_bucket = Rails.application.secrets.aws_bucket
      config.aws_acl    = 'private'

    #acl: "private", # accepts private, public-read, public-read-write, authenticated-read, aws-exec-read, bucket-owner-read, bucket-owner-full-control
      # Optionally define an asset host for configurations that are fronted by a
      # content host, such as CloudFront.
      config.asset_host = Rails.application.secrets.aws_asset_host

      # The maximum period for authenticated_urls is only 7 days.
      config.aws_authenticated_url_expiration = 60 * 60 * 24 * 7
      # config.aws_authenticated_url_expiration = 2

      # Set custom options such as cache control to leverage browser caching
      config.aws_attributes = {
        expires: 1.week.from_now.httpdate,
        cache_control: 'max-age=604800'
      }

      config.aws_credentials = {
        access_key_id:     Rails.application.secrets.aws_access_key_id,
        secret_access_key: Rails.application.secrets.aws_secret_access_key,
        region:            Rails.application.secrets.aws_region # Required
      }

    end

    end
    end
