Detecting EC2 account name from inside an EC2 running instance

  • 772

Is there a way for a running instance, via the meta-data facility to find out the ec2 account name that the instance is running under?

Looking up the meta-data service yields the following items we can query:

ami-id
ami-launch-index
ami-manifest-path
hostname
instance-id
local-ipv4
public-keys/
reservation-id
security-groups

None of which satisfy this - any ideas?

    Pass the EC2 account data you need as user data to the instance. You can retrieve the user data passed to an instance by running curl http://169.254.169.254/1.0/user-data on the instance.
