Thumbor Migration
Thumbor Upgrade & Improvements
|
Background
editThumbor is a smart imaging service that enables on-demand cropping, resizing, applying filters and optimizing of images. The Wikimedia media thumbnailing infrastructure is based on Thumbor, which has evolved and released various new versions since the Wikimedia Foundation adopted it.
Over the years we have been unable to keep pace with the latest releases to Thumbor and related technologies, resulting in an outdated service that is difficult to maintain and contribute to. To add additional complexity, Wikimedia Thumbor uses a community tool, Thumbor Community Core, to provide modifications as extensions to the Thumbor tool.
In order to simplify Thumbor maintenance, take advantage of new version features, address issues within the service, and invite more contributors from the movement, we seek to upgrade and streamline Wikimedia Thumbor. This project details the efforts of the Wikimedia Foundation to deliver this work.
What is changing
editOur goal is to update/migrate Thumbor (both Mediawiki and Community Core) to Thumbor version 7 and Python 3, while retaining and/or improving existing Thumbor performance and functionality. We will attempt to minimize drastic changes or impacts to end-users, ensuring that we communicate potential large impacts or changes via updates on this page.
Key Milestones
- Update or Replace Thumbor Community Core to support Thumbor version 7 and Python 3
- Update Wikimedia Thumbor to support Thumbor version 7 and Python 3
- Dockerization & Migration to Kubernetes
- Pre-Release Testing & Release to Production
- Upgrade to latest available versions (if needed)
