How can I use Docker to manage the dependencies of my Python application?
Asked 3 months ago
I'm working on a Python application and considering using Docker for dependency management. How can I effectively use Docker to manage the dependencies of my app?

Go over the steps below to manage your app dependencies with Docker:
- First, create a Dockerfile for your Python project.
- Then, in the Dockerfile, define the base Python image, copy your application code, and use `pip` to install the required dependencies from a "requirements.txt" file. This ensures that your application runs within an isolated environment with its dependencies encapsulated.
- Once you've installed the dependencies, consider using multi-stage builds to reduce the final image size.
- Last but not least, you should look to regularly update the "requirements.txt" file and rebuild the Docker image to keep your dependencies up to date.
