  • Launchpad Entry: server-lucid-euca2ools

  • Created: 2009-11-24

  • Packages affected: euca2ools

Summary

This spec includes improvements to Euca2ools package to:

  • make it more of a drop in replacement for ec2-ami-tools and ec2-api-tools
  • make it behave more consistently with other ubuntu tools.

Release Note

The euca2ools package has been improved. It can now read account information from a config file rather than the environment or command line, and is improved as a "drop-in" replacement for ec2-ami-tools and ec2-api-tools.

Rationale

The ec2-ami-tools and ec2-api-tools are common utilities for interacting with ec2. However, these tools are in multiverse because they are not free software. We want to provide suitable free software replacements in main. Much of the functionality needed is already provided by python-boto and euca2ools, but some improvements are needed.

User stories

  • As a ec2 user I have several scripts that interact with ec2 by using the ec2-api-tools packages provided by Amazon. I would like to migrate these scripts to a package supported by Ubuntu. I would like for these scripts to also function consistently when configured to use a Eucalyptus or EC2 cloud.

Assumptions

Design

There isn't really any significant design changes needed. The changes will be applied to the euca2ools package in a way consistent with its current code base. The most visible change will be in supporting a system wide and per-user config file.

Fix the following bugs:

  • 485106 : support a config file

  • 485113 : add --region support for all euca2ools

  • 486128 : be more consistent in environment variable usage

  • 439366 : add kernel and ramdisk output (eki/aki) to euca-describe-images

  • 479836 : make euca2ools not depend on ec2-api-tools to operate with ec2

  • add command line completion to euca2ools

Migration

These changes should all be backwards compatible.

Implementation

See work items in status whiteboard.

Test/Demo Plan

TODO This need not be added or completed until the specification is nearing beta.

Unresolved issues

None.

BoF agenda and discussion

Euca2ools are the preferred command line clients for UEC. There are some improvements that could be made to these, those include, but are not limited to:

  • config file based configuration (as opposed to .eucarc/environment)
  • --region support for euca2ools (I [smoser] believe that euca2ools do not support '--region' but rather only re-setting EC2_URL. I could be wrong).

The following are bugs/issues that were brought up in the session, or soon after:

  • config bug 485106

  • region bug: 485113

  • environment consistency: 486128

  • kernel-ramdisk ids not provided in euca-describe-images: 439366
