[BUG] Static files broken

Describe the bug I want to expose api endpoint from which I can download static directory. I get 2 unexpected behaviors:

1. When I want to reach my endpoint 0.0.0.0/static I see No operations defined in spec!
2. From tutorials(mentioned below) I understood it takes file from my app directory? Unless I copy it to root of my OS I get error raise RuntimeError(f"Directory '{directory}' does not exist").

This is really important for my home project to make sense so any input is really appreciated because I’m stuck on this.

To Reproduce Code:

from starlette.staticfiles import StaticFiles
from fastapi import FastAPI

app = FastAPI(title="static_api")
app.mount("/static", StaticFiles(directory="static"))

Dockerfile:

FROM python:3.7
RUN pip install aiofiles fastapi uvicorn python-multipart 
EXPOSE 80
COPY ./app /app
COPY ./static /static

CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "80"]

I use docker build -t myimage . and docker run -p 80:80 myimage.

Expected behavior Download static directory(or at least any file from this dir) from 0.0.0.0/static

Environment: Docker above.

@yaronv you might be able to pass absolute paths without needing to actually hard code an absolute path by doing something like:

from pathlib import Path

current_file = Path(__file__)
current_file_dir = current_file.parent
project_root = current_file_dir.parent
project_root_absolute = project_root.resolve()
static_root_absolute = project_root_absolute / "static"  # or wherever the static folder actually is

Obviously you can reduce the number of lines involved, I just made it more verbose to make it clear what was going on.

Or you could also use an environment variable/config as you noted.

Even if this answer comes a little late, maybe it helps others, because I got into the same problem in the beginning.

I am not sure if this is a bug either? Because it’s called static file and not static directory.

So you won’t be able to request a folder, only a file, which has to be explicit.

0.0.0.0/static/existing_file

if you want to get files as folder you could zip your files to one file

0.0.0.0/static/existing_files.zip

If the error result is that the folder was not found, then a wrong specification must have happened. The following should run, if you want static inside you app-folder:

from starlette.staticfiles import StaticFiles
from fastapi import FastAPI

app = FastAPI(title="static_api")
app.mount("/static", StaticFiles(directory="app/static"))

So you don’t need to copy the static folder in dockerfile additionaly.
