Dockerized Python & React/Vite Demo

This repository contains two main examples:

1. BasicApp
   A simple Python (Flask) application containerized with Docker.

2. ComposeApp
   A full stack using Docker Compose with:

   • A Python (Flask) backend (back).
   • A React/Vite frontend (front).

Running the BasicApp

1. Navigate to the BasicApp directory.

2. Build the Docker image:

   docker build -t basic-app .

3. Run the container:

   docker run -p 5000:5000 basic-app

4. Access the app at http://localhost:5000/hello-world.

Running the ComposeApp

1. Navigate to the ComposeApp directory.

2. Build and run the containers using Docker Compose:

   docker compose up -d --build

   This command will build images (if needed) and run the services in detached mode.

3. If you only changed a single service and want to rebuild just that service without touching the others, you can run:

   docker compose up -d --no-deps --build <service-name>

   For example:

   docker compose up -d --no-deps --build back

Default Ports

• The backend listens on port 5000 (e.g., http://localhost:5000/hello-world).
• The frontend listens on port 3000 or 80 (depending on your Dockerfile/Compose configuration).

Useful Commands

• To view logs:

  docker compose logs -f

• To stop the services:

  docker compose down

Modifications

• BasicApp: Update app.py or requirements.txt as needed, then rebuild the image.
• ComposeApp: Adjust Dockerfile settings for both the backend and frontend, as well as docker-compose.yml, to customize your stack. Rebuild only the changed service with --no-deps --build if you want faster rebuilds.
