Docker has become a first class citizen in Visual Studio 2017 and porting your applications to containers is easier than ever. The advantages of this technology become really evident in Azure DevOps, when we can easily leverage the flexibility of containers in a number of areas. This talk will showcase how Docker makes possible to build our code in Azure DevOps by using the most up-to-date SDKs, to create a fully working temporary environment to run our integration tests and to even use containers in order to run UI tests. Then we will present a possible approach to distribute the images in Azure Container Registry, isolating development images from the production ones. As a last step, we are going to explore how Azure Kubernetes Service fits into the loop, and how PaaS services in Azure can be created on the fly, integrated with our application in Kubernetes, and monitored altogether when live.
