Creating On-Demand Clusters in EC2 with Puppet

Posted by Jakub Holý on May 5, 2012

For a recent project I needed to be able to start on-demand clusters of machines in Amazon EC2. We needed each instance in a cluster to allow SSH and sudo access for all team members and to install and configure the software appropriate for that cluster (“database” node or “testclient” node).

You can see the results of my effort using EC2 command-line tools, Puppet etc. at the project’s Puppet GitHub repository, the setup is described in detail in its README.

(Tips for improvements are welcome. And not, Star Cluster isn’t what we needed.)
