Which of the following is the correct syntax to run a Flask app named app using uWSGI with 4 workers on port 8080?

Auwsgi --http :8080 --wsgi-file app.py --processes 4

Buwsgi --http 8080 --module app:app --workers 4

Cuwsgi --socket 8080 --module app --workers 4

Duwsgi --http :8080 --module app:app --processes 4

Step-by-Step Solution

Solution:

Step 1: Understand uWSGI options
To run uWSGI with HTTP on port 8080, use --http :8080. The Flask app is specified with --module app:app. Number of workers is set with --processes 4.
Step 2: Eliminate incorrect options
uwsgi --http :8080 --wsgi-file app.py --processes 4 uses --wsgi-file without --callable app, assuming default 'application' callable instead of 'app'. uwsgi --http 8080 --module app:app --workers 4 uses --workers which is invalid; uWSGI uses --processes. uwsgi --socket 8080 --module app --workers 4 uses --socket without HTTP, which is not the question's requirement.
Final Answer:
uwsgi --http :8080 --module app:app --processes 4 -> Option D
Quick Check:
uWSGI HTTP port and workers = --http :port --processes [OK]

Quick Trick: Use --http :port and --processes for uWSGI workers [OK]
