Docker best practises used

• Specify every COPY in the Dockerfile to avoid redundant transfers and optimize for rapid development.
• Mindfully break down Dockerfile commands to optimize layers to account for the most often changing files.
• Document Dockerfile via comments.
• Use VSCode Docker extension for linting.
• Use small python:3.9-slim-buster base image.
• Use '.dockerignore' to avoid leaking secrets and copying unnecessary files.
• Create root-less user for security.
• Expose ports to be able to connect to the app from outside.
• Run docker scan to audit for security vulnerabilities.
