The Cluster API Migration Retrospective: Live migrating hundreds of clusters to Cluster API

Описание: Joe Salisbury

Cluster API has become the industry standard for managing Kubernetes clusters, taking care of the heavy lifting of cluster operations.

However, migrating to Cluster API can still be challenging, especially for organisations heavily invested in existing cluster management tools.

This talk presents Giant Swarm's journey from a custom operator-based Kubernetes cluster management system to Cluster API, including the live migration of hundreds of production clusters of major enterprises such as adidas and Vodafone.

The driving force for the migration will be covered, followed by challenges encountered during the migration, concluding with a discussion of the observed benefits and differences seen post-migration.

Attendees will come away with an understanding of potential risks and challenges to be considered when migrating to Cluster API, a better insight into the expectations and efforts required, and the benefits of using this upstream project.
