使用AWS :: EC2 :: Instance类获取AWS实例的user_data

Question

I want to get the user_data of a ec2 instance from that instance. I looked at documentation of class AWS::EC2::Instance at the link http://docs.aws.amazon.com/AWSRubySDK/latest/AWS/EC2/Instance.html

and tried getting user_data like this

require 'aws-sdk' puts AWS::EC2::Instance.instance.user_data

But I think this is not the right way it works . Can any one let me know how to get user_data of a instance.

Answer 1

Try this:-

require 'aws-sdk'

EC2 = AWS::EC2.new(
 :access_key_id => 'access_key_id',
 :secret_access_key => 'secret_access_key')

instance = EC2.instances['i-9e516a95']
puts instance.user_data

Note :- 'i-9e516a95' is a particular instance_id and make sure that this instance is running.
