Hello,

I configured my metadata service and it works fine. I am able to inject 
ssh pub-key's to the guest VM.

 From my guest VM when i execute meta-data curl cmd, I get this below 
output.

I know 169.254.169.254 http port is mapped to metadata service on 
controller node. But i want to know where is the meta data stored in? is 
it per instance basis ? Also the below curl cmd doesn't use any 
instance-id, how it is mapping to particular instance ?

    /root at testnewrelic:~# curl http://169.254.169.254/latest/meta-data/

    ami-id
    ami-launch-index
    ami-manifest-path
    block-device-mapping/
    hostname
    instance-action
    instance-id
    instance-type
    kernel-id
    local-hostname
    local-ipv4
    placement/
    public-hostname
    public-ipv4
    public-keys/
    ramdisk-id
    reservation-id
    security-groups
    /


Thanks,
