func NewControlPlaneActiveVersionController ¶

func NewControlPlaneActiveVersionController(
	cosmosClient database.DBClient,
	activeOperationLister listers.ActiveOperationLister,
	informers informers.BackendInformers,
) controllerutils.Controller

NewControlPlaneActiveVersionController creates a new controller that updates Status.ControlPlaneVersion.ActiveVersions from the management cluster content (HostedCluster status stored in ManagementClusterContent).

func NewControlPlaneDesiredVersionController ¶

func NewControlPlaneDesiredVersionController(
	cosmosClient database.DBClient,
	clusterServiceClient ocm.ClusterServiceClientSpec,
	activeOperationLister listers.ActiveOperationLister,
	informers informers.BackendInformers,
) controllerutils.Controller

NewControlPlaneDesiredVersionController creates a new controller that manages the desired control plane version. It periodically checks each cluster and sets the desired version based on the OCPVersion logic documented in the ServiceProviderCluster type. The controller name remains "ControlPlaneVersion" for compatibility.

func NewNodePoolVersionController ¶

func NewNodePoolVersionController(
	cosmosClient database.DBClient,
	clusterServiceClient ocm.ClusterServiceClientSpec,
	activeOperationLister listers.ActiveOperationLister,
	informers informers.BackendInformers,
) controllerutils.Controller

NewNodePoolVersionController creates a new syncer that reads node pool versions from Cluster Service. TODO: improve this description

func NewTriggerControlPlaneUpgradeController ¶

func NewTriggerControlPlaneUpgradeController(
	cosmosClient database.DBClient,
	clusterServiceClient ocm.ClusterServiceClientSpec,
	activeOperationLister listers.ActiveOperationLister,
	informers informers.BackendInformers,
) controllerutils.Controller

NewTriggerControlPlaneUpgradeController creates a new controller that triggers control plane upgrades. It monitors clusters where the desired version differs from the actual version and calls the version service API to initiate the upgrade.

The version service API is idempotent:

• If desiredVersion == current cluster version: NOOP
• Otherwise: Initiate the upgrade to desiredVersion

func NewTriggerNodePoolUpgradeController ¶

func NewTriggerNodePoolUpgradeController(
	cosmosClient database.DBClient,
	clusterServiceClient ocm.ClusterServiceClientSpec,
	activeOperationLister listers.ActiveOperationLister,
	informers informers.BackendInformers,
) controllerutils.Controller

NewTriggerNodePoolUpgradeController creates a new controller that triggers node pool upgrades. It monitors node pools where the desired version differs from the actual version and creates a NodePoolUpgradePolicy in Cluster Service to initiate the upgrade.
