Docker in launchSettings.json

[AceHack]

Please give documentation on how to add volume mounts. I need to add a custom volume mount into my image.

To report new issues, use the Report a Problem tool. The GitHub Issue Tracker for the aspnet/Tooling repo is now deprecated in favor of the Report a Problem tool.

If you encounter a problem with Visual Studio, we want to know about it so that we can diagnose and fix it. By using the Report a Problem tool, you can collect detailed information about the problem, and send it to Microsoft with just a few button clicks. See here for more details.

@barrytang This is not an issue but a question. Report a Problem is not for questions, where do I go for questions?

[barrytang]

I apologize. I reopened the issue now. I will see if I can find someone that I can add here to help.

@AceHack I'll try to help as best I can. Can you provide a little more context? Which set/version of (VS) tools are you using, what kind of a project(s) is it, etc.?

Ive expanded on the question a lot on stackoverflow since this was closed.

Ah, I see now.

You can add arbitrary arguments to the Docker build and Docker run commands via the DockerfileBuildArguments and DockerfileRunArguments MSBuild properties, respectively. For example:

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <DockerfileRunArguments>-v "C:\HostFolder:/ContainerFolder:ro"</DockerfileRunArguments>
  </PropertyGroup>
</Project>

If those arguments need to vary from debug session to debug session, you can add conditions to the properties such that one applies to each selectable build configuration.

@philliphoff Those arguments look exactly like what I need. A couple of questions:

• Are they documented somewhere? Can't find any result when I Google them (except for this page and the StackOverflow question.
• How exactly do they work? Does it detect that I'm launching docker.exe in launchsettings.json? Does it detect the DOTNET_RUNNING_IN_CONTAINER environment variable? Does it only work in a Docker project?

DockerComposeProjectPath seems to be another one.
