First, I was learning how to work with Docker from the command line.
Then, wanted to see what I could do with Visual Studio.
My goal is to use Visual Studio 2017 to create an ASP.NET Core web API and develop, debug, test and deploy that web API using containers.
The solution has two projects: one is the usual ASP.NET Core project and the other is one called Docker Compose:
As you can see, it's the same Program.cs and Startup.cs that you can see in any other ASP.NET Core application, the same type of controller, so there's nothing in the C# code that knows anything about Docker or containers or the operating environment that it's going to be in.
The only thing Docker related about this particular project, is the presence of a Docker file (you can see it opened in the image with the instructions to build another image).
The particular image is going to be a Linux image. So, one thing I needed to do was going to Docker menu and switch to Linux containers:
Steps to reproduce the issue
- Launch VS2017
- Create a new project, C#, ASP.NET Core Web Application (enabling Docker support)
- Run and debug using Docker (F5)
Expected behavior
Application runs and allows its debugging.
Actual behavior
Build fails due to error:
