LinuxCon+ContainerCon Europe 2016

In this talk Yury Tsarev will go through practical example of building infrastructure-as-code with a strong test-driven approach. While having opinionated tools selection the audience will be provided with generic framework to build on where the components are fully replaceable. Yury strongly believes that infrastructure code should be treated like any other code. This means apply a test driven development model, storing it in a source control system and building a regression test suite. He suggests doing this with Test Kitchen, a pluggable and extensible test orchestrator that originated in the Chef community. Using Test Kitchen’s docker driver, a docker container can be used to simulate a machine under test. Then Serverspec can verify that the configuration code properly setup the machine. Shell mocking is used to bypass external dependencies and docker limitations.
