Visual Studio Code Ubuntu aspnet core 2 container debugging

Question

I googled and looked on stackoverflow but couldn't find a solution.

Setup:

Host OS: Ubuntu

ASPNet Core 2

Dotnet 2.0

I have two containers, one container for MySQL and other for dotnet core. I was able to run it without installing CLR Debugger. After installing CLR debugger in one container, I am trying to use Visual Studio Code to debug aspnet core 2 app running in that container. I am getting following error:

"The pipe program 'bash' exited unexpectedly."

Only option is to "open Launch.json" and only bash command in launch.json is:

        "pipeTransport": {            
            "pipeProgram": "/bin/bash",            
            "pipeCwd": "${workspaceRoot}",            
            "pipeArgs": ["-c",            
                "docker exec -i devexamapp_debug_1 /clrdbg/clrdbg --interpreter=mi"],
            "debuggerPath": "/vsdbg/vsdbg"

Debug console shows following:

Starting: "/bin/bash" -c "docker exec -i devexamapp_debug_1 /clrdbg/clrdbg --interpreter=mi" "/vsdbg/vsdbg --interpreter=vscode"

If I run "/bin/bash" -c "docker exec -i devexamapp_debug_1 /clrdbg/clrdbg --interpreter=mi" "/vsdbg/vsdbg --interpreter=vscode" in a console window then it works 100% fine withotu any error.

What am I missing? Any help?

Thanks

Probably it is running some wrong command, with total combination. See if you could figure what command was actually run? — Tarun Lalwani

Thanks for reply. Only thing I can check from Visual Studio Code is what it prints in "Debug Console" at bottom. Is there a way to check what is it running? Some log or something? — SharpCoder

Edit-1: 14-Oct

You need to have the debugger installed in your Docker image. You can do the same by adding below to your dockerfile

WORKDIR /vsdbg 
RUN curl -SL https://aka.ms/getvsdbgsh | bash /dev/stdin -v latest -l /vsdbg

Then you need to updated the pipeTransport in launch.json as below

"pipeTransport": { 
   "pipeProgram": "docker", 
   "pipeCwd": "${workspaceRoot}", 
   "pipeArgs": ["exec -i devexamapp_debug_1"], 
   "debuggerPath": "/vsdbg/vsdbg", 
   "quoteArgs": false 
}

Thanks, I tried it but I get following error now: Starting: "docker" exec -i devexamapp_debug_1 /clrdbg/clrdbg --interpreter=mi /vsdbg/vsdbg --interpreter=vscode Error from pipe program 'docker': ERROR: Unknown argument '/vsdbg/vsdbg'. I tried to remove "debuggerPath" but that didn't work either. It says "debuggerPath" is required.

Try changing "debuggerPath": "/vsdbg/vsdbg" to "debuggerPath": "/clrdbg/clrdbg" and see if it helps? also try using you original approach with "quoteArgs": false added and see if that helps?

First tried "pipeArgs": ["exec -i devexamapp_debug_1 /clrdbg/clrdbg --interpreter=mi"],"debuggerPath": "/clrdbg/clrdbg" - error was "This version of the C# extension no longer supports connecting to clrdbg and install vsdbg". Tried original with "quoteArgs":false and error was: error from pipe program, docker command has wrong usage
