You must be in the root of your Rails app to succesfully run the script.

require 'aws-sdk-elasticbeanstalk' # v2: require 'aws-sdk' Aws.config.update({region: 'us-west-2'}) eb = Aws::ElasticBeanstalk::Client.new s3 = Aws::S3::Client.new app_name = 'MyRailsApp' # Get S3 bucket containing app app_versions = eb.describe_application_versions({ application_name: app_name }) av = app_versions.application_versions[0] bucket = av.source_bundle.s3_bucket s3_key = av.source_bundle.s3_key # Get info on environment envs = eb.describe_environments({ application_name: app_name }) env = envs.environments[0] env_name = env.environment_name # Create new storage location resp = eb.create_storage_location() puts "Created storage location in bucket #{resp.s3_bucket}" resp = s3.list_objects({ prefix: s3_key, bucket: bucket }) # Create ZIP file zip_file_basename = SecureRandom.urlsafe_base64.to_s zip_file_name = zip_file_basename + '.zip' # Call out to OS to produce ZIP file cmd = "git archive --format=zip -o #{zip_file_name} HEAD" %x[ #{cmd} ] # Get ZIP file contents zip_contents = File.read(zip_file_name) key = app_name + "\\" + zip_file_name resp = s3.put_object({ body: zip_contents, bucket: bucket, key: key }) date = Time.new today = date.day.to_s + "/" + date.month.to_s + "/" + date.year.to_s eb.create_application_version({ process: false, application_name: app_name, version_label: zip_file_basename, source_bundle: { s3_bucket: bucket, s3_key: key }, description: "Updated #{today}" }) eb.update_environment({ environment_name: env_name, version_label: zip_file_basename })
