Containers provide an impressive list of new benefits to a tech org, but it can sometimes be difficult to explain them to the uninitiated. This session explains the benefits of containerization in the context of a real-world open-source deployment of a Go web service using Terraform, CoreOS, Docker, Fleet, and Vulcan on AWS. We'll discuss testing, integration, canary deploys and how we achieve 20 minute development cycles (from request to production deployment) with zero downtime.
