Kubernetes v1.33: Octarine (The Color of Magine)

The theme for Kubernetes v1.33 is Octarine: The Color of Magic, inspired by Terry Pratchett’s Discworld series. This release highlights the open-source magic that Kubernetes enables across the ecosystem.

Kubernetes v1.33 is a testament to the enduring power of open-source innovation, where hundreds of contributors from around the world work together to create something truly extraordinary. Each release builds upon the other, creating something greater than we could achieve alone.

The release logo was made by Nina Polshakova and Aaron Ray using Inkscape, an open source vector graphics editor.
