How can I optimize my Dockerfile for a Python application?

How can I optimize my Dockerfile for a Python application?

To optimize your Dockerfile, start by using a smaller base image like 'python:3.9-slim'. This reduces the image size.

What about caching dependencies?

You can cache dependencies by copying only the requirements file first, installing them, and then copying the rest of your application.

Should I use multi-stage builds?

Yes, multi-stage builds can help you keep your final image smaller by separating build dependencies from runtime dependencies.

Any tips for reducing the final image size?

Remove unnecessary files and use the 'dockerignore' file to exclude files that aren't needed in the final image.
