Command-line option to turn off logging configuration

[def-gthill]

I'm using uvicorn in projects that set up a specific logging configuration on startup. But uvicorn does its own configuration for its loggers and overrides the project-specific configuration, leading to inconsistent logging formats. I can suppress this when starting uvicorn programmatically via uvicorn.run by passing log_config=None, but there seems to be no way to do this from the CLI—the only options are to accept uvicorn's default or pass a separate configuration file.

My suggestion is to have a separate flag (e.g. --no-log-config) to suppress logging configuration.

+1 to this - am basically forced to write a python entrypoint using uvicorn.run to get around this issue.

Additionally, when passing reload=True to uvicorn.run my own logging configuration that i have set up (via logging.dictConfig) seems to get discarded or overridden somewhere.

EDIT: #2209 somewhat reflects this issue.
