docker run command for ASP.NET Core and Visual Studio 2017
You can add the <DockerfileRunArguments> tag to the <PropertyGroup> section in your *.csproj file and put additional run parameters there.
e.g.
<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
<DockerfileRunArguments>-p 5000:6000</DockerfileRunArguments>
</PropertyGroup>
</Project>
You cannot change the command , however you may create a new Debug Profile and make modifications to the Application Arguments...something like this
