How to Create Docker Images for ASP.NET Core

Microsoft collaborates with the Docker team and community to facilitate running ASP.NET Core web apps in Docker containers, guiding users through creating Docker images and using prebuilt ones. The tutorial explains how to build a custom Docker image using a Dockerfile, which serves as a recipe for creating an image, and a .dockerignore file to optimize the build process by ignoring unnecessary files. It provides detailed instructions on building and running Docker images, both custom and prebuilt, and demonstrates accessing an app locally via HTTP and HTTPS, emphasizing the importance of HTTPS for secure communication. The guide also covers generating self-signed development certificates on different operating systems to enable HTTPS, ensuring data protection through encryption. Throughout the tutorial, users are encouraged to familiarize themselves with Docker commands and the use of ASP.NET Core in containerized environments, laying the groundwork for future exploration of Docker image creation methods for .NET applications.
