PuppetConf 2013

Continuous deployment of puppet code feels like a holy grail; naive approaches are a minefield for stability. Code that works on existing machines but doesn’t work on newly provisioned machines is easy to write. Whilst there are tools like puppet-rspec to help with testing your code, they don’t help with system level tests. One way to solve this problem is to build an infrastructure and run end to end tests against it. This talk will cover the approach my team has taken to this; defined by the development cycle we wanted - test driven development, fast feedback and confidence in the repeatability of builds with an automated and continuous deployment pipeline to take changes from the first push through to production.
