Is there a way to log python print statements in gunicorn?

Question

With my Procfile like this:

web: gunicorn app:app \\
    --bind \"$HOST:$PORT\" \\
    --debug --error-logfile \"-\" \\
    --enable-stdio-inheritance \\
    --r         


        

Answer 1

In python 3, adding flush=True in each print statement works for my flask/gunicorn app.

E.g.

gunicorn --bind 0.0.0.0:8080 server --log-level debug

No particular flags are required.

See if this helps.
