💡 Hint

Common Mistakes

Using default sync worker which blocks async calls.

Using eventlet or gevent which are not compatible with Uvicorn.

Gunicorn uses the UvicornWorker class to run FastAPI apps asynchronously.

💡 Hint

Common Mistakes

Setting workers to 1 when more concurrency is needed.

Using too many workers causing resource exhaustion.

The -w option sets the number of worker processes; here it is 2.

hard

Fix the error in the command to run Gunicorn with Uvicorn workers on port 8080.

FastAPI

gunicorn -w 3 -k uvicorn.workers.UvicornWorker myapp:app [1] 0.0.0.0:8080

💡 Hint

Common Mistakes

Using --port alone without address.

Using --host which is not a Gunicorn option.

Gunicorn uses -b or --bind to specify the address and port to bind.

Fill both blanks to bind Gunicorn to localhost on port 5000.

FastAPI

gunicorn -w 2 -k uvicorn.workers.UvicornWorker myapp:app [1] [2]

💡 Hint

Common Mistakes

Binding to 0.0.0.0 when localhost is intended.

Using --host instead of -b or --bind.

Use -b followed by address:port to bind Gunicorn to localhost:5000.

5fill in blank

hard

Fill all three blanks to run Gunicorn with 3 workers, Uvicorn worker class, and bind to all interfaces on port 8000.

FastAPI

gunicorn [1] [2] [3] myapp:app

Drag options to blanks, or click blank then click option'

A-w 3

B-k uvicorn.workers.UvicornWorker

C-b 0.0.0.0:8000

D--workers 4

Attempts:

💡 Hint

Common Mistakes

Using --workers 4 instead of -w 3.

Omitting the worker class option.

Binding to localhost instead of all interfaces.

Use -w 3 for workers, -k for worker class, and -b for binding address and port.
