Provisioning an Ubuntu 12.04 instance with PostgreSQL using Chef, following Ch 11.1 - 'PostgreSQL' in Ben Dixon's Leanpub Reliably Deploying Rails Applications (find here).

Dependencies

• ruby (2.0)
• knife-solo (0.4)
• berkshelf (2.0)

Commands

1. berks install
2. knife solo prepare root@<my server ip>
3. knife solo cook root@<my server ip>

Result

The foregoing got PostgreSQL onto my server (and use and installation configuration was as Ben's chapter promised), however I was unable to add the Monit server:
