Docker Custom Build PDF Generator

This project demonstrates how to build and run a custom docker container using Dockerfile. For this project, a PDF Generator app is created and run using Python and ReportLab library. Here’s the project overview:

1. Create the Python app, requirements, and mock data
2. Create a Dockerfile with the custom setup commands
3. Build the image from the Dockerfile and run it in a container

Project Structure

docker-tutorial/2-pdf-generator/
├── data/
│   └── report_data.json    # Demo data (JSON format)
├── generated_pdfs/         # Directory to store generated PDFs (using Docker volumes)
├── app.py                  # Python application to generate PDFs
├── Dockerfile              # Dockerfile to containerize the app
├── requirements.txt        # Python dependencies

Running with Docker

1. Build the Docker Image:

   cd 2-pdf-generator
   docker build -t pdf-generator .
   

2. Run the Docker Container:

   docker run --rm -v $(pwd)/generated_pdfs:/app/generated_pdfs pdf-generator
   

This will mount the generated_pdfs directory from your local machine to the container and generate the PDFs inside the folder.

Checking Container Status

To check if your container is running:

docker ps

Cleaning Up

To remove the container:

docker rm <CONTAINER_ID>

To remove the pdf-generator image:

docker rmi pdf-generator
