=== Release 0.1 ===
'''==== Goals:'''====
* Add in a new build step to Buildbot
* Allow Buildbot to connect with Amazon's EC2 service
==== Downloads ====
Basically, the first thing that needs to be done is add a new step to Buildbot's build process    [http://matrix. Once a new step has been added, the next step is to make this new build step access my EC2 accountsenecac. on.ca/~awdelyea/EC2_build_step_nokeys.py EC2_build_step_nokeys.py]
After I can actually access my EC2 account through Buildbot, then a possible next step would be     Note: You will need to make Buildbot check to see if I have any open Virtual Instances running already (no point in starting another instance if ones running already)install the boto library located [http://boto.googlecode.com/files/boto-0.9a.tar.gz here].
One thing that may need to be kept in mind is that Amazon charges 10 cents per hour, or part of an hour, per instance. So, each time you start a new instance, it costs 10 cents. The best way I can think of doing this is make each instance you start, last for at least an hour, so that if you start another build in 10 mins, you can continue to use the same instance instead of starting a new one.
For ==== About ==== Basically, this, Buildbot would need to run a service on the OS first version attempts to constantly check connect to see if an instance is approaching EC2 account, and then display the 1 hour markconnection information to show that it has connected. It uses a library called "boto", and not running any build slavesthis library is used to connect to all of [http://www.amazon.com/gp/browse. Not quite sure how Ihtml?node=3435361 Amazon'd do thats Web Services] To use this in a Buildbot configuration file, simply call the connect_to_ec2() function, but it's something to keep which takes in mindas paramaters, an Amazon id key, and an Amazon secret keyExample:<pre> connection = connect_to_ec2("73ghf9h38fh", "75vo87rVO*&V%O7o75v7i%i75I&5li7%i75")</pre> ----

2007-10-11: Found a python EC2 library that has all of the functions I will need for interacting with EC2. Just need to write a custom build step to run these library functions.
 
2007-10-12: Release v0.1 is complete and available for download.
 
2007-10-12: Release v0.2 loosely defined. More detail to follow.
