==== About ====
+
* [[Buildbot and EC2/0.2]]
  
−
Basically, this first version attempts to connect to an EC2 account, and then display the connection information to show that it has connected.
+
* [[Buildbot and EC2/0.3]]
  
−
It uses a library called "boto", and this library is used to connect to all of [http://www.amazon.com/gp/browse.html?node=3435361 Amazon's Web Services]
+
* [[Buildbot and EC2/0.4]]
  
−
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.

==== About ====
 
−
 
 
−
To use the EC2 service with Buildbot, there needs to be some way for Buildbot to dynamically generate a list of build slaves. These build slaves (or just slaves) are hosted as a virtual machine on the EC2 service.
 
−
 
 
−
This will work by extending the BuildSlave class to add in some new functionality for starting a new EC2 instance. So, every time you add a new slave to the slave list, another instance will be spwaned, so that you can spawn as many instances as you think you will need to complete a build.
 
−
 
 
−
This new BuildSlave class will start a new instance, which will then proceed to send the connection information of the master to the new instance. How exactly, I'm not exactly sure, because it takes a minute for the virtual instance to start up.
 
−
 
 
−
The rest basically takes care of itself.
 
−
 
 
−
Still have to think about how to turn the new EC2 instances off after the build is done.
 
−
 
 
−
====0.2.1====
 
−
=====About=====
 
−
I have made a slight modification to the EC2BuildSlave.<br/>
 
−
It now requires some additional input, because I had been hardcoding some values in, and thats sloppy, so I corrected it to allow you to put any variable parameters in the config file.<br/>
 
−
Basically, you will lay out a new EC2BuildSlave like this:
 
−
 
 
−
    from buildbot.EC2BuildSlave import EC2BuildSlave
 
−
    c['slaves'] = [EC2BuildSlave("bot1name", "bot1passwd", "public key", "private key", "dns", "instance-id")]
 
−
    //Where dns = www.whatever.com:8898, or 88.123.55.456:8898
 
−
    //and public/private key is your public/private key from Amazon
 
−
    //and instance-id is the instance you would like to launch ("ami-87d530ee")
 
−
 
 
−
=====Downloads=====
 
−
* [[http://zenit.senecac.on.ca/wiki/imgs/Buildbot_EC2.zip Patch]]
 
−
    The EC2BuildSlave.py goes into your python's framework folder for Buildbot (note: on my mac, this is<br/>  /Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/buildbot/)

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.

2007-09-17: Project claimed!

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.

2007-11-17: Release v0.2 is complete and available for download: can start an instance and start an EC2BuildSlave

2007-11-21: Release v0.2.1 is complete and available for download: now to include variable EC2 users, and instances, and DNS'

2007-12-13: Release v0.3 is complete and available for download: easier to install and setup, can use to build projects now

2008-01-14: Release v0.4 Defined. In the process of getting accounts and machines for Try Server Farm.

2008-02-01: Task List and Release News is being moved to individual Release Pages. See individual Releases for more information.
