Setup: FastAPI running inside Docker container, python3.12 image. Connection to it via VSCode remote attach debugger This works if the application is started via python -m debugpy --listen 0.0.0.0:5680 --wait-for-client main.py docker run --mount type=bind,source=$(pwd),target=/home/app -p 5680:5680 -p 8080:8080 my_image However if I start it with python main.py including the lines: debugpy.listen(("0.0.0.0", 5680)) debugpy.wait_for_client() I get that debugpy can't listen on 5680 as the address is already in use debugpy.listen(("0.0.0.0", 5680)) File "/usr/local/lib/python3.12/site-packages/debugpy/public_api.py", line 31, in wrapper return wrapped(*args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.12/site-packages/debugpy/server/api.py", line 133, in debug log.reraise_exception("{0}() failed:", func.__name__, level="info") File "/usr/local/lib/python3.12/site-packages/debugpy/server/api.py", line 131, in debug return func(address, settrace_kwargs, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.12/site-packages/debugpy/server/api.py", line 260, in listen raise RuntimeError(str(endpoints["error"])) RuntimeError: Can't listen for client connections: [Errno 98] Address already in use It'd be really great if I could do things this way -- multiple use cases and less code change for development environments. What am I doing wrong with this? Continue reading...
