How can I use my firebase credentials in a Flask application that I want to deploy in a AWS elastic beanstalk?

Question

Inside my .zip source boudle I have:

• templates/
• application.py
• serviceKey.json
• requirements.txt

It runs locally in my machine with the following code, but when I deploy it in AWS elastic beanstalk it doesn't work.

from flask import Flask, request, jsonify, render_template
import firebase_admin
from firebase_admin import credentials, db

application = app = Flask(__name__)

cred = credentials.Certificate('./serviceKey.json') 
default_app = firebase_admin.initialize_app(cred, {"databaseURL": "<URL_to_my_firebasedb>"})

Answer 1

Ok my code was right, my problem had something to do with an invalid requirements.txt error that says: requirements.txt returned non-zero exit status 1.

My solution of my problem was to create other .zip source boundle that does not include the requirements.txt but the venv foler that I had in my local computer.

So the new .zip source boudle looks like this:

• templates/
• venv/
• application.py
• serviceKey.json
