DotNetDay18: VSTS Release Pipelines with Kubernetes by Marc Müller

Nowadays, everybody is talking about Docker and Microservices. But how does that affect me as a developer working with the Microsoft stack? In this session Marc shows how to build an automated release pipeline using Visual Studio and VSTS which deploys ASP.NET Core Microservices into a Kubernetes infrastructure. In addition to the full developer stack needed to build the pipeline, the session covers advanced topics, such as staging environments and load-balancing.
