For a recent project, I needed to create a Docker image for a Python application that is being handled with Poetry. I already done it one year ago using distroless images, that provide minimal Docker images based on Debian without package managers, shells or any other tools commonly found in traditional images, and optimized for security and size. But after the release of Debian 12 and Poetry 2.0, and so much improvements on the ecosystem during this year, this time I wanted to take the opportunity to create a more secure and minimal image, and to know what would be the best practices for doing so.
