The Procfile
is like a configuration file to our app.
Hence we shall define this file.
Note:
We need to let Heroku know that we are using gunicorn
. So we mention web: gunicorn
in the Procfile.
Followed by web: gunicorn
, we write app:app
in the Procfile.
For app:app
, the format is <<filename>>:<<flaskapp_in_that_file>>
The app
to the left side of :
indicates the name of the file where we initialized the Flask and defined routes and methods. Since it is app.py
in our case, we just write app
to the left side of the :
.
The app
to the right side of :
indicates the name of the Flask object inside app.py
. If we have a quick look inside the app.py
file(using nano app.py
), we initialized Flask by writing app = Flask(__name__)
. Thus we write app
to the right-side of :
.
Make sure to be inside the Image-Classification-App
directory:
cd ~
cd Image-Classification-App
Create a file named Procfile
using the following command in the console:
nano Procfile
Also, Write the following in the Procfile
. One space should be there between web:
and gunicorn
.
web: gunicorn app:app
Then click Ctrl+X
, hit the key y
, and then the Enter
key.
