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, -------------- next part -------------- An HTML attachment was scrubbed...
