1) add gem ‘aws-sdk’ and then bundle install.

add to spree.rb located at config/intializers/spree.rb. you don’t want to change anything in this code

attachment_config = {

s3_credentials: {
access_key_id: ENV[‘AWS_ACCESS_KEY_ID’],
secret_access_key: ENV[‘AWS_SECRET_ACCESS_KEY’],
bucket: ENV[‘S3_BUCKET_NAME’]
},

storage: :s3,
s3_headers: { “Cache-Control” => “max-age=31557600” },
s3_protocol: “https”,

$ heroku config:set AWS_ACCESS_KEY_ID=your_access_key_id
$ heroku config:set AWS_SECRET_ACCESS_KEY=your_secret_access_key
