VSCode > HyperV-Centos > Docker container > attach to running process with debugger

[zljubisic]

I am using VS Code in windows 10 to connect to local HyperV Centos 7 (Connect to host...).
Now, I am in Centos and I would like to set break point in running docker (swarm service) container.

In order to do so I can "Remote-Containers: Attach to Running Container...", but in that case I will just enter the container. I don't see the option to attach to the running process inside of container (set by docker entrypoint).

I see "Debug: Attach to Node Process" so I hope something like this exists for python processes as well.

Let's say that I have container with fastapi or celery running process inside of it.
Can I somehow attach to their processes and set break point in order to see what is going on?

You want to attach to the running process in the container. See https://code.visualstudio.com/docs/python/debugging for the docs on how to do that.

You need to set up a launch.json to make the connection work, otherwise VS Code doesn't have the communication set up with the debugger to then surface the controls and such within VS Code.

Looks like for javascript it is not the case. If you look at https://blog.logrocket.com/how-to-debug-node-js-apps-in-visual-studio-code/#:~:text=The%20easiest%20way%20to%20start,left%20corner%20of%20the%20application.
at the very beginning it is explained how to use launch.json.
But in chapter "Attach an External Node.js process", it is explained how to attach to (already) running process.
I would like to have such option for python too.

Ah, then that would be a feature request. I will convert this into an issue.
