Overview ¶

Package failuredomainrollout provides a controller that monitors cluster.status.failureDomains and triggers rollouts on KubeAdmControlPlane when there are meaningful changes to failure domains that impact the current control plane placement.

A meaningful change is defined as: - A failure domain currently in use by the control plane being disabled (controlPlane: false) - A failure domain currently in use by the control plane being removed - A failure domain is overutilized and can be improved by spreading the control plane across more failure domains

The controller does NOT trigger rollouts when: - New failure domains are added but existing ones remain valid - Changes to failure domains that are not currently in use by the control plane
