Basically, the first thing that needs to be done is add a new step to Buildbot's build process. Once a new step has been added, the next step is to make this new build step access my EC2 account.

After I can actually access my EC2 account through Buildbot, then a possible next step would be 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).

    Note: You will need to 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 this, Buildbot would need to run a service on the OS to constantly check to see if an instance is approaching the 1 hour mark, and not running any build slaves. Not quite sure how I'd do that, but it's something to keep in mind.

To use this in a Buildbot configuration file, simply call the connect_to_ec2() function, which takes in as paramaters, an Amazon id key, and an Amazon secret key.

Project Name

Buildbot and EC2

Project Description

The BuildBot is software for automatically building and testing other software. EC2 is Amazon's "Elastic Compute Cloud", a service that lets you run Virtual Machines on Amazon's computing grid using a web API. It would be awesome if BuildBot had an EC2 module, and could spawn Virtual Machines on-demand to perform tasks. Conveniently, BuildBot is written in Python, and there's a Python library for interfacing with EC2.

Project Details

Release 0.1

Goals

  • Add in a new build step to Buildbot
  • Allow Buildbot to connect with Amazon's EC2 service

Downloads

    EC2_build_step_nokeys.py

    Note: You will need to install the boto library located here.


About

Basically, this first version attempts to connect to an EC2 account, and then display the connection information to show that it has connected.

It uses a library called "boto", and this library is used to connect to all of Amazon's Web Services

To use this in a Buildbot configuration file, simply call the connect_to_ec2() function, which takes in as paramaters, an Amazon id key, and an Amazon secret key.

Example: 

    connection = connect_to_ec2("73ghf9h38fh", "75vo87rVO*&V%O7o75v7i%i75I&5li7%i75")
