I’m running a FastAPI app in a Docker container. For the app to work it needs access to its secrets, which are in a folder inside the app (for local development only), however, it can’t find the secrets directory.

My file structure inside the container’s working directory is the following:

project/
├── app/
│   └── secrets/
│       └── LOCAL_DEV/
├── environments/
│   └── LOCAL_DEV/
└── main.py

The working directory is set as “project”, and adding the following debug statement:

BASE_DIR = Path(__file__).resolve().parent
logger.debug(f"Current base directory: {BASE_DIR}")

Confirms that the current directory is “/project”, however, when it’s time to extract the secrets, the program fails with:

directory "app/secrets/LOCAL_DEV" does not exist

Everything runs fine when running it outside of the container, what am I missing here?
