To be fair, from the article it says that they built the bulk of the tool and did the first migration in a 6-week cycle. mrsk looks fairly straight forward, and feels like Capistrano but for containers. The first commit of mrsk is only on January 7th of this year. In less than a six-week cycle, we built those operational foundations, shaped mrsk to its functional form and had Tadalist running in production on our own hardware.
