I am relatively new to Python and I am trying to deploy a Flask app to AWS Beanstalk. I have followed the official tutorial and went through a lot of the resources available online (here or elsewhere) regarding deployment issues with Flask / Django on Beanstalk. No success, I keep getting errors I cannot fix. Below the structure of my app:
|-application.py
|-config.py
|-const.py
|-requirements.txt
|-app/
|--__init.py__
|--views.py
|--models.py
|--static/
|--templates/
My application.py
from app.views import application
application.run(debug=False)
The first few lines of my views.py file that contains the declaration of the Flask app:
from flask import Flask, render_template, redirect, url_for, session, request, abort
from flask_bootstrap import Bootstrap
from . models import Datalayer, Config, Signin
from . util import check_user
from flask_basicauth import BasicAuth
from flask_bcrypt import Bcrypt
from faker import Faker
from htmlmin.minify import html_minify
fake = Faker()
application = app = Flask(__name__)
app.config.from_object('config')
bootstrap = Bootstrap(app)
basic_auth = BasicAuth(app)
bcrypt = Bcrypt(app)
And finally the content of the /var/log/eb-activity.log

I have no beanstalk config file (yet) but I have performed a manual install of: yum install libffi-devel
My first question is how do we determine when we need to add -devel packages to our deployment? (I fixed a first deployment issue with the installation of the devel package above.)
I assumed all the necessary packages / libraries would be installed with the requirements.txt?
My second question is do you have any clue as to why this deployment is failing? (will hopefully be linked to the first question?)
Thanks in advance for the help,
Stf
