Deploy to Google Cloud Functions

Prerequisites

Setup

  1. Copy and configure .env file:

    cp .env.example .env

  2. Edit .env with your settings:

    GCP_PROJECT_ID=your-project-id
GCP_REGION=us-central1
GCF_FUNCTION_NAME=flask-app
GCF_ALLOW_UNAUTHENTICATED=true

Deploy

Linux/Mac:

./deploy-gcf.sh

Windows:

deploy-gcf.bat

That's it! The script will deploy your app to Cloud Functions.

What the script does

  • Loads configuration from .env
  • Sets your GCP project
  • Deploys to Cloud Functions Gen 2 with Python 3.11
  • Uses main.py as entry point
  • Outputs the function URL

Important Notes

  • Uses main.py as entry point (imports Flask app from app.py)
  • Supports multiple endpoints in a single deployment
  • Cold starts may occur for infrequent requests

Manual Deployment

If you prefer manual control:

gcloud functions deploy flask-app \
  --gen2 \
  --runtime python311 \
  --trigger-http \
  --allow-unauthenticated \
  --entry-point main \
  --region us-central1 \
  --source .
