Announcing our Docker image for CI

We are thrilled to announce the release of our new Docker image called six, designed specifically for developers who are still working on Jython or Python 2.7 projects. This Docker image is tailored for seamless integration into Azure Pipelines and GitHub workflows, making it easier than ever to manage and deploy your legacy projects.

Key features

• Supports Python 2.7.18 for legacy projects.
• Compatible with Python versions from 3.8 to 3.13 for modern development needs.
• Optimized for Azure Pipelines and GitHub workflows.
• Lightweight and easy to use.

Why six?

We created the six Docker image because GitHub dropped Python 2.7 support from their default images back in June 2023 (See: actions/runner-images#7401). With six, you can continue working on your Python 2.7 projects without worrying about compatibility issues in your CI/CD workflows or pipelines.

Naming things is hard, but since we aim to provide support for both Python 2 and 3 we were inspired by the Python six package (six at PyPI).
