You’ve heard that containers can simplify development. Did you know that they can also be used to create complete developer experiences using infrastructure-as-code? Development Containers represent a new frontier for application developers, providing a way to get started developing quickly on any platform or in the cloud. Whether building an open source project or a commercial application, this enables people to quickly create working environments and start contributing code. In this Pre-conference Workshop, Ken Muse of GitHub explores how to create your first dev container and making your custom environment available in GitHub Codespaces. We’ll dive into customizing the developer experience, as well as how to personalize your experience working in a dev container.
