Docker light images to support Machine Learning (ML) in Python

Overview

That project⁠ produces light OCI⁠(Docker-compliant) images, which provide Python environments, ready to use and to develop with Artificial Intelligence (AI), Machine Learning (ML) and Data Science. These images are based on the latest Python-ready Linux distributions.

As well explained in a PythonSpeed article from June 2023⁠, the best light images for Python production operations are based on Debian (the latest stable release being, as of end 2023, Debian 12, also known as Bookworm⁠). For historical reasons (and for the challenge!), Alpine-based distributions are still maintained too.

These Python OCI light images are aimed at deploying Data Science applications on operational environments such as cloud-based Kubernetes clusters or services (e.g., AWS EKS⁠, Azure AKS⁠, IBM/RedHat OpenShift v4⁠ or Google GKE⁠).

The author of this repository also maintains Data Science Python OCI images for every day development purposes in a dedicated GitHub repository⁠ and Docker Hub space. Thanks to Docker multi-stage builds⁠, one can easily have in the same Docker specification files two images, one for every day data science work, and the other one to deploy the corresponding applications onto production environments.

The Docker images of this repository just add some standard ML-related Python packages such as NumPy, Pandas and Dash/Plotly, on top of the native images maintained by the Docker Python project⁠:

In the OCI image, Python packages are installed by the pip utility. For testing purposes, outside of the container, Python virtual environments may be installed thanks to Pyenv and pipenv, as detailed in the dedicated procedure⁠ on the Python induction notebook sub-project⁠.

Any additional Python module may be installed either:

With pip and some requirements.txt dependency specification file:

$ python -mpip install -r requirements.txt

In a dedicated virtual environment, controlled by pipenv through local Pipfile (and potentially Pipfile.lock) files, which should be versioned:

$ pipenv --rm; pipenv install; pipenv install --dev

On the other hand, the OCI images install those modules globally.

The Docker images of this repository are intended to run any collection of Dash applications.

Simple use

Download the Docker image:

$ docker pull infrahelpers/python-light

Launch Dash or Flask within the Docker image (where <port> corresponds to the local port on which Dash or Flask is launched; the default is 8050):

$ docker run -d -p <port>:8050 infrahelpers/python-light

Interact with the Dash application in a Web browser

The sample Dash application (run from the Docker image) is now available on the Web browser: http://localhost:8050⁠ Note that the port (8050 by default) may be changed as per your convenience.

Build your own container image

Clone the Git repository⁠:

$ mkdir -p ~/dev/ml && cd ~/dev/ml
$ git clone https://github.com/machine-learning-helpers/docker-python-light.git
$ cd docker-python-light

(Optional) Push the newly built images to Docker Hub. That step is usually not needed, as the images are automatically built everytime there is a change on GitHub⁠)
