Python 3 + Beautiful Soup 4 on Alpine Linux
50K+
Official Python image with Beautiful Soup 4 and lxml installed for Alpine Linux + Debian Slim.
This project is based upon logiqx/python-lxml. The result is a lightweight image of Python and Beautiful Soup 4.
Note: This image is not meant to be run directly since it does not include things such as a non-privileged user. It is really intended for use within builds of runtime containers for Python scripts.
The example Dockerfile for Alpine Linux converts a collection of Jupyter notebooks to regular Python scripts, building a lightweight runtime image. The employment of a multistage build ensures that the final image is kept nice and small.
