i trying tag error messages elastic beanstalk environment. there way programmatically determine environment in ec2 instance inside elastic beanstalk?

i using ruby on rails ruby way nice, can port language.

i have rails project , doing inside in order determine environment our ec2 instance part of.

below code doing more 1 check, file check makes sure running code on ec2 instance. second set of url calls grabbing ec2 instance id along aws region being used. uses previous 2 pieces of data find environment-name using aws-sdk. it's little ugly gets job done.

require 'net/http' require 'aws-sdk'  uuid = file.readlines('/sys/hypervisor/uuid', 'r') if uuid     str = uuid.first.slice(0,3)     if str == 'ec2'         metadata_endpoint = 'http://169.254.169.254/latest/meta-data/'         dynamic_endpoint = 'http://169.254.169.254/latest/dynamic/'         instance_id = net::http.get( uri.parse( metadata_endpoint + 'instance-id' ) )         document = net::http.get( uri.parse( dynamic_endpoint + 'instance-identity/document') )         parsed_document = json.parse(document)         region = parsed_document['region']         ec2 = aws::ec2::client.new(region: region)         ec2.describe_instances({instance_ids:[instance_id]}).reservation_set[0].instances_set[0].tag_set.each |tag|             if tag.key == 'elasticbeanstalk:environment-name'                 @env_name = tag.value             end         end     end end
