You're a developer who knows nothing to Microservices. Which is fine, except that you need to start coding your next Microservices-based application using ASP.NET Core and Docker. Don't worry: I have you covered. I've been training hundreds of developers like you during 16 years, and converted my experience into this book. I know from experience teaching what takes more time to learn in Microservices, and will spend time only where appropriate. Plus this book is packed with exercises which build up into a full project: you develop two interdependent Microservices, each exposing a CRUD JSON API. You publish them in a Docker repository and run them in Docker. Read this book, and you can code your Microservices within a week.
