Its very easy these days to run an .NET application in docker container, that too with the IDE support of Docker out-of-box to create the docker file.

But, this post is more towards a specific problem as the heading says in this post, how to run .NET core app with specific launch profile in docker container.

.NET app usually comes with 2 default profiles one with IISExpress and another one with the name of your project, which will be the default profile used while running CLI command

launchSettings.json

For the launchSettings.json above, in order to run the profile LocalDev, we need to just use the following command

dotnet run

.NET will automatically take the first profile as default profile by design.

First profile automatically taken, note the http://localhost:5001
