Configuration of my cluster, maybe it will be also usefull for Yours (also it can be seen as a sample usage of Vfs, Vos and ClusterManagement tools).

It not only automates the deployment process, it fully configures servers from the clean state, see below.

Here's how I'm using it, let's say I want to deploy my app to clean box(es) with remote ssh access, all I need to do - type:

rake deploy

It's clever ennought to determine that before deploying app it needs to prepare machines, and It will:

• install & configure: git, mail, ruby, mongodb, nginx, ...
• ensure that mongodb and nginx is running
• only then it will deploy the application

Sample output:
