Django project debug in docker container doesn't start #2313

@jmejia32 Can you share the project you are encountering this issue in? Or at least the Docker and docker-compose files, tasks.json, and launch.json? Also, can you share the logs from the following places:
Debugging in Docker is done differently; the app is run by running Debugpy in the container, which is supposed to connect back to the host. It sounds like Debugpy may not be able to connect back to the host and so VSCode sits there waiting for the connection. If this is the case the "Python Debug Console" output probably has the most important info. EDIT: Ah, I see your launch and tasks in the bug in the VSCode repo, as well as the |

For Terminal > Python Debug Console, I mean this: |

@bwateratmsft No, I'm sorry for being a little dumb hahaha. And the entry keeps hidden for me:

Hm, that's not good. Our debug launch config in launch.json resolves down to a Python configuration, so basically once the Docker container is started, we hand control over to the Python extension--they use |

Yep, there it is: |
|
Everything looks pretty normal to me; I'm not able to reproduce at least on Windows. In theory it shouldn't matter the host OS. @int19h do you know what might be happening? It seems like the Python extension is not executing the Python debug command ( |
|
@jmejia32 I have one theory. I was able to get the same symptoms to reproduce if the Can you run this command and share the output? |
|
Yes, the output is |
|
Ok, if you put that into your launch config as below, does debugging work? Note, it goes at the same level as
It will give a yellow underline but that's OK, you can ignore that. |

Man, that was awesome!! It works. Finally I can debug my project, i'm so thankful. Congrats!! You deserve my respect.
|

I'm glad to help! This step shouldn't be necessary though 😕 The most likely explanation I can think of is that somehow our code to get that IP address failed. The exact command line we use is Do you have a custom shell configured in VSCode, and does the command with the above ordering/syntax/quoting still work on your OS? |
|
@bwateratmsft yeah, actually I use fish as default shell. The commands explained here works without issues. |

I found the root cause of this. The |

This is now fixed in Docker extension version 1.7.0. |

In vscode, when I start the debug in my local computed (no docker), debug starts completely but when I start debug with docker, the container builds and starts while vscode ui waiting for connection and never "starts" debugging process.
