[Bug 461156] Re: User data is not parsed correctly by Eucalyptus in some cases

[Mathias Gug]

To fix this issue an SRU is needed for karmic:

1. fix euca-run-instances to only encode user-data once to mimic what ec2-run-instances does
2. fix eucalyptus soap|rest interface to not fail when user-data is sent by euca-run-instances.


** Description changed:

  User data supplied using "euca-run-instances --user-data-file" is not decoded before being presented to the instance. 
  Inside the instance, "curl http://169.254.169.254/latest/user-data" should fetch the decoded user data, whereas eucalyptus will return a base64 and url encoded string. This breaks ec2-run-user-data from the ec2-init package, rendering instance configuration using the user-data mechanism unusable. 
  
  EC2 documentation at http://docs.amazonwebservices.com/AWSEC2/2007-03-01/DeveloperGuide/AESDG-chapter-instancedata.html states that EC2 will return decoded data (i don't have a ec2 account so i can't confirm this):
  "The user data must be base64-encoded before being submitted to the API. The API command-line tools perform the base64-encoding for you. The data will be base64 decoded before being presented to the instance."

+ =================
+ Karmic release notes:
+ 
+ user-data not usable by guest instances
+ 
+ Starting an instance with euca-run-instances and user-data (either using
+ the -d option the -f option) will store the user data  in base64
+ encoding. Accessing the user data from the instance at
+ http://169.254.169.254/latest/user-data will return the user data in
+ base64 encoding. Because of this bug ec2-init is unable make use of
+ user-data. In order to use this data it must first be decoded. A fix for
+ this issue is expected to be provided in a post-release update
+ immediately after the Ubuntu 9.10 release.
