Python venv Instructions

Run at the Project root folder.

python3 -m venv .venv
source .venv/bin/activate
pip3 install -r requirements.txt
pip3 install --upgrade pip

To deactivate the venv: deactivate

Set Environment Variables -

export FLASK_APP=app
export FLASk_ENV=development

Start Server

python3 -m flask run --host=0.0.0.0 --port=5001

ngrok Setup with Brew and Use

AWS App Client only allows for https and localhost in Callback URLs, so you may need to use ngrok to tunnel http traffic to https via ngrok.

brew install --cask ngrok
ngrok http https://127.0.0.1:5000

Instructions for Updating the code manually on EC2

Go to the parent directory of your frontend/ Ensure that the pem file is also in this directory

zip frontend.zip frontend/
scp -i "memerr-kp.pem" "frontend.zip" ec2-user@ec2-54-86-68-35.compute-1.amazonaws.com:/home/ec2-user
ssh -i "memerr-kp.pem" ec2-user@ec2-54-86-68-35.compute-1.amazonaws.com
unzip frontend.zip -d tmp/ # replace All
cd /home/ec2-user/frontend
source .venv/bin/activate
pip3 install -r requirements.txt
export FLASK_APP=app
export FLASk_ENV=development
python3 -m flask run --host=0.0.0.0 --port=5000

Instructions for running Gunicorn

After running the above. Run this

gunicorn --workers 3 --bind unix:/home/ec2-user/frontend/app.sock -m 007 app:app

Instructions for NGINX setup

sudo yum update
sudo yum install nginx
sudo systemctl start nginx
sudo systemctl enable nginx
sudo vim /etc/nginx/nginx.conf

Update this file by adding a server block (see nginx.config). For Debug/Testing you will use Flask default server; for PROD, you will switch to Gunicorn and swap the proxy_pass line below and restart NGINX. Then run

sudo nginx -t
sudo systemctl restart nginx

Instructions for Self-signed cert on EC2

sudo mkdir -p /etc/nginx/ssl/
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/nginx/ssl/nginx.key -out /etc/nginx/ssl/nginx.crt

unzip frontend.zip -d tmp/
