Why I Still Use Python Virtual Environments in Docker (via) Hynek Schlawack argues for using virtual environments even when running Python applications in a Docker container. This argument was most convincing to me:
I'm responsible for dozens of services, so I appreciate the consistency of knowing that everything I'm deploying is in
/app
, and if it's a Python application, I know it's a virtual environment, and if I run/app/bin/python
, I get the virtual environment's Python with my application ready to be imported and run.
Also:
It’s good to use the same tools and primitives in development and in production.
Also worth a look: Hynek's guide to Production-ready Docker Containers with uv, an actively maintained guide that aims to reflect ongoing changes made to uv itself.
