Azure Kubernetes Fleet Manager (Fleet) is now generally available. It enables multi-cluster and at-scale scenarios for Azure Kubernetes Service (AKS) clusters. Platform admins who are managing Kubernetes fleets with a large number of clusters often face challenges staging their updates across clusters in a safe and predictable way. Azure Kubernetes Fleet Manager allows admins to orchestrate updates across multiple clusters by using update runs, stages, and groups.
Azure Kubernetes Fleet Manager now also offers an update orchestration feature. As part of update orchestration, you are now able to store templates for update runs in the form of update strategies and the ability to set node image consistency as a desired outcome throughout the update run.
