Dear All, I made available a service that implements the EC2 metadata protocol. For more information, please see:
http://docs.aws.amazon.com/AWSEC2/2008-08-08/DeveloperGuide/AESDG-chapter-instancedata.html The main benefit is that you can get instance meta-data from inside the machine, most notably the user-data and public keys. And because it is compatible with EC2, you can use cloud-init or other tools without any modification(*). https://help.ubuntu.com/community/CloudInit You can find the code and instructions on the following link: https://bitbucket.org/ricardoduarte/opennebula-metadata The code reuses the /var/lib/one/.one/ec2_auth credentials. Please let me know if you find any bug. I plan to write a small guide with examples on how to use it with cloud-init. Regards, Ricardo (*) while cloud-init itself does not need any modification, you have to make sure the instance has a valid IP before cloud-init runs, either by having DHCP or by running the context scripts before cloud-init. One simple way to ensure that, with Ubuntu, is to add the following to /etc/init/one-context.conf # /etc/init/one-context.conf - opennebula context script # contextualizes instance start on starting cloud-init-nonet task exec /etc/init.d/vmcontext
