What are the best practices for using Docker with Flask?
When using Docker with Flask, it's important to keep your images small, use a multi-stage build, and manage dependencies carefully.
Can you explain what a multi-stage build is?
A multi-stage build allows you to use multiple FROM statements in your Dockerfile, which helps in reducing the final image size by separating build dependencies from runtime dependencies.
How can I manage environment variables in Docker for my Flask app?
You can manage environment variables in Docker by using the -e
flag in the docker run
command or by defining them in a .env
file and using the --env-file
option.
What should I include in my Dockerfile for a Flask application?
Your Dockerfile should include the base image, install dependencies, copy your application code, and specify the command to run your Flask app.
