PyQuote

simple python/flask app for printing random quotes to a webpage. Used to test containerization in OpenShift

Requirements

• Podman
• Python 3 (for building the image)
• Internet access to pull base images (or pre-pulled images offline)

File Structure

pyquote/
├── app.py              # Flask app logic
├── Dockerfile          # Image build instructions
├── requirements.txt    # Python dependencies
├── podman-compose.yml  # Defines pod with app and DB containers
├── init.sql            # SQL init script for DB setup and sci-fi quote seeding

How to Run

1. Build the Flask app container

   podman build -t pyquote .

2. Start the pod with app and database

   podman play kube podman-compose.yml

3. Visit the app Open your browser to http://localhost:5000 to see a random quote.

Database Setup

The PostgreSQL container will automatically initialize the database using init.sql. To enable this, mount the script into the container with:

podman run -d \
  --name quotes-db \
  -e POSTGRES_USER=quoteuser \
  -e POSTGRES_PASSWORD=quotepass \
  -e POSTGRES_DB=quotes \
  -v ./init.sql:/docker-entrypoint-initdb.d/init.sql:ro \
  postgres

This will automatically:

• Create the quotes table
• Insert 20 famous sci-fi quotes

You can then start the Flask app container and retrieve quotes from the database.
