light-python

Debian 9 based, production-ready and lightweight Python3 container.

Docker Hub: https://hub.docker.com/r/camilo0365r/light-python

Features

  • Based on the stretch-slim tag from the official Debian Docker registry.
  • Python 3.6 based on glibc Standard C library, instead of musl. This avoids compatibility issues when pip installs (and compiles) various libraries from source.
  • Just the necessary system dependencies to deploy production-ready containers.
  • Downloaded Image size approx. 140MB (Official images can be as big as 600MB+).

Why another Python image?

At the time of writing (October 2017) the official Python Docker registry does not include a barebones and lightweight Python image based on glibc (not musl as in Alpine-based images) and Debian 9 (Stretch).
