The brief hello.py
import os
from flask import Flask
from dotenv import load_dotenv
app = Flask(__name__)
dotenv_path = os.path.join(os.path.dirname(__file__), '.env')
load_dotenv(dotenv_path)
@app.route('/')
def index():
SECRET_KEY = os.environ.get("SECRET_KEY")
DATABASE_PASSWORD = os.environ.get("DATABASE_PASSWORD")
return SECRET_KEY + DATABASE_PASSWORD + os.linesep
picks up its environment from a .env file
export FLASK_APP=/home/ubuntu/tough/
export SECRET_KEY=ABCD
export DATABASE_PASSWORD=EFGH
After launching the server (using either flask run or gunicorn), asking for curl localhost:8000 reports the expected ABCDEFGH, the two env-vars picked up from .env.
So far so good.
Now we ask supervisor to launch hello.py for us
[program:hello]
command=/home/ubuntu/venv/bin/gunicorn -b localhost:8000 hello:app
directory=/home/ubuntu/tough/
user=ubuntu
stdout_logfile=/home/ubuntu/tough/logs/hello_out.log
stderr_logfile=/home/ubuntu/tough/logs/hello_err.log
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true
[supervisord]
logfile=/home/ubuntu/tough/logs/hello-supervisord.log
pidfile=/home/ubuntu/tough/supervisord.pid
Everything is perfectly fine on macOS (High Sierra). The two environment variables are picked up fine. But on Ubuntu (18.04) I get
File "/home/ubuntu/tough/hello.py", line 14, in index
return SECRET_KEY + DATABASE_PASSWORD + os.linesep
TypeError: unsupported operand type(s) for +: 'NoneType' and 'NoneType'
What might be the difficulty of picking up env-vars on Ubuntu, one that doesn't show up on Darwin?
