Enable Hot Reloading in Docker Container #1771

"Hot Reloading Not Working in Docker Container" Live code updates inside the Docker container are not taking effect as expected. Currently, hot reloading requires a full container rebuild using docker compose up --build for changes to be reflected, which slows down the development process.

Solution: How to Enable Hot Reloading?

1. Use Bind Mounts Modify docker-compose.yml to mount the code into the container:

services:
 vulnerablecode:
    volumes:
      - .:/app  # Syncs local changes with the container

2. Enable Gunicorn Auto-Reload Update the Gunicorn command to include the --reload flag , allowing automatic reloading when code changes:

command: 
      gunicorn --reload vulnerablecode.wsgi:application -b :8000 --timeout 600 --workers 8

This setup allows the dockerized application to reflect the changes automatically when code changes are detected.

How to Test ?

1.Modify the code (Python files or static UI elements).
2. Check the container logs for updates:
sh docker compose logs -f vulnerablecode
3. Refresh the UI in the browser.
4. Verify the changes without rebuilding the container.

Expected Outcome:

• Code modifications should trigger an automatic reload inside the container.
• No need to manually rebuild the container after every change.
