**Supported Annotations:** -| Annotation | Note | -|:-----------------------------------------------------------------|:------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| -| clusterctl.cluster.x-k8s.io/skip-crd-name-preflight-check | Can be placed on provider CRDs, so that clusterctl doesn't emit an error if the CRD doesn't comply with Cluster APIs naming scheme. Only CRDs that are referenced by core Cluster API CRDs have to comply with the naming scheme. | -| clusterctl.cluster.x-k8s.io/delete-for-move | DeleteForMoveAnnotation will be set to objects that are going to be deleted from the source cluster after being moved to the target cluster during the clusterctl move operation. It will help any validation webhook to take decision based on it. | -| clusterctl.cluster.x-k8s.io/block-move | BlockMoveAnnotation prevents the cluster move operation from starting if it is defined on at least one of the objects in scope. Provider controllers are expected to set the annotation on resources that cannot be instantaneously paused and remove the annotation when the resource has been actually paused. | -| unsafe.topology.cluster.x-k8s.io/disable-update-class-name-check | It can be used to disable the webhook check on update that disallows a pre-existing Cluster to be populated with Topology information and Class. | -| unsafe.topology.cluster.x-k8s.io/disable-update-version-check | It can be used to disable the webhook checks on update that disallows updating the `.topology.spec.version` on certain conditions. | -| cluster.x-k8s.io/cluster-name | It is set on nodes identifying the name of the cluster the node belongs to. | -| cluster.x-k8s.io/cluster-namespace | It is set on nodes identifying the namespace of the cluster the node belongs to. | -| cluster.x-k8s.io/machine | It is set on nodes identifying the machine the node belongs to. | -| cluster.x-k8s.io/owner-kind | It is set on nodes identifying the owner kind. | -| cluster.x-k8s.io/owner-name | It is set on nodes identifying the owner name. | -| cluster.x-k8s.io/paused | It can be applied to any Cluster API object to prevent a controller from processing a resource. Controllers working with Cluster API objects must check the existence of this annotation on the reconciled object. | -| cluster.x-k8s.io/disable-machine-create | It can be used to signal a MachineSet to stop creating new machines. It is utilized in the OnDelete MachineDeploymentStrategy to allow the MachineDeployment controller to scale down older MachineSets when Machines are deleted and add the new replicas to the latest MachineSet. | -| cluster.x-k8s.io/delete-machine | It marks control plane and worker nodes that will be given priority for deletion when KCP or a MachineSet scales down. It is given top priority on all delete policies. | -| cluster.x-k8s.io/cloned-from-name | It is the infrastructure machine annotation that stores the name of the infrastructure template resource that was cloned for the machine. This annotation is set only during cloning a template. Older/adopted machines will not have this annotation. | -| cluster.x-k8s.io/cloned-from-groupkind | It is the infrastructure machine annotation that stores the group-kind of the infrastructure template resource that was cloned for the machine. This annotation is set only during cloning a template. Older/adopted machines will not have this annotation. | -| cluster.x-k8s.io/skip-remediation | It is used to mark the machines that should not be considered for remediation by MachineHealthCheck reconciler. | -| cluster.x-k8s.io/remediate-machine | It can be applied to a machine to manually mark it for remediation by MachineHealthCheck reconciler. | -| cluster.x-k8s.io/managed-by | It can be applied to InfraCluster resources to signify that some external system is managing the cluster infrastructure. Provider InfraCluster controllers will ignore resources with this annotation. An external controller must fulfill the contract of the InfraCluster resource. External infrastructure providers should ensure that the annotation, once set, cannot be removed. | -| cluster.x-k8s.io/replicas-managed-by | It can be applied to MachinePool resources to signify that some external system is managing infrastructure scaling for that pool. See [the MachinePool documentation](../developer/architecture/controllers/machine-pool.md#externally-managed-autoscaler) for more details. | -| cluster.x-k8s.io/skip-machineset-preflight-checks | It can be applied on MachineDeployment and MachineSet resources to specify a comma-separated list of preflight checks that should be skipped during MachineSet reconciliation. Supported preflight checks are: All, KubeadmVersionSkew, KubernetesVersionSkew, ControlPlaneIsStable. | -| topology.cluster.x-k8s.io/defer-upgrade | It can be used to defer the Kubernetes upgrade of a single MachineDeployment topology. If the annotation is set on a MachineDeployment topology in Cluster.spec.topology.workers, the Kubernetes upgrade for this MachineDeployment topology is deferred. It doesn't affect other MachineDeployment topologies. | -| topology.cluster.x-k8s.io/dry-run | It is an annotation that gets set on objects by the topology controller only during a server side dry run apply operation. It is used for validating update webhooks for objects which get updated by template rotation (e.g. InfrastructureMachineTemplate). When the annotation is set and the admission request is a dry run, the webhook should skip validation due to immutability. By that the request will succeed (without any changes to the actual object because it is a dry run) and the topology controller will receive the resulting object. | -| topology.cluster.x-k8s.io/hold-upgrade-sequence | It can be used to hold the entire MachineDeployment upgrade sequence. If the annotation is set on a MachineDeployment topology in Cluster.spec.topology.workers, the Kubernetes upgrade for this MachineDeployment topology and all subsequent ones is deferred. | -| topology.cluster.x-k8s.io/upgrade-concurrency | It can be used to configure the maximum concurrency while upgrading MachineDeployments of a classy Cluster. It is set as a top level annotation on the Cluster object. The value should be >= 1. If unspecified the upgrade concurrency will default to 1. | -| machine.cluster.x-k8s.io/certificates-expiry | It captures the expiry date of the machine certificates in RFC3339 format. It is used to trigger rollout of control plane machines before certificates expire. It can be set on BootstrapConfig and Machine objects. The value set on Machine object takes precedence. The annotation is only used by control plane machines. | -| machine.cluster.x-k8s.io/exclude-node-draining | It explicitly skips node draining if set. | -| machine.cluster.x-k8s.io/exclude-wait-for-node-volume-detach | It explicitly skips the waiting for node volume detaching if set. | -| pre-drain.delete.hook.machine.cluster.x-k8s.io | It specifies the prefix we search each annotation for during the pre-drain.delete lifecycle hook to pause reconciliation of deletion. These hooks will prevent removal of draining the associated node until all are removed. | -| pre-terminate.delete.hook.machine.cluster.x-k8s.io | It specifies the prefix we search each annotation for during the pre-terminate.delete lifecycle hook to pause reconciliation of deletion. These hooks will prevent removal of an instance from an infrastructure provider until all are removed. | -| machinedeployment.clusters.x-k8s.io/revision | It is the revision annotation of a machine deployment's machine sets which records its rollout sequence. | -| machinedeployment.clusters.x-k8s.io/revision-history | It maintains the history of all old revisions that a machine set has served for a machine deployment. | -| machinedeployment.clusters.x-k8s.io/desired-replicas | It is the desired replicas for a machine deployment recorded as an annotation in its machine sets. Helps in separating scaling events from the rollout process and for determining if the new machine set for a deployment is really saturated. | -| machinedeployment.clusters.x-k8s.io/max-replicas | It is the maximum replicas a deployment can have at a given point, which is machinedeployment.spec.replicas + maxSurge. Used by the underlying machine sets to estimate their proportions in case the deployment has surge replicas. | -| controlplane.cluster.x-k8s.io/skip-coredns | It explicitly skips reconciling CoreDNS if set. | -| controlplane.cluster.x-k8s.io/skip-kube-proxy | It explicitly skips reconciling kube-proxy if set. | -| controlplane.cluster.x-k8s.io/kubeadm-cluster-configuration | It is a machine annotation that stores the json-marshalled string of KCP ClusterConfiguration. This annotation is used to detect any changes in ClusterConfiguration and trigger machine rollout in KCP. | -| controlplane.cluster.x-k8s.io/remediation-in-progress | It is a KCP annotation that tracks that the system is in between having deleted an unhealthy machine and recreating its replacement. | -| controlplane.cluster.x-k8s.io/remediation-for | It is a machine annotation that links a new machine to the unhealthy machine it is replacing. | +| Annotation | Note | Managed By | Applies to | +|:------------------------------------------------------------|:-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|:------------------------------------------------------|:-------------------------------------------| +| cluster.x-k8s.io/cloned-from-groupkind | It is the annotation that stores the group-kind of the template from which the current resource has been cloned from. | Cluster API | Any Cluster API resource cloned from a template | +| cluster.x-k8s.io/cloned-from-name | It is the annotation that stores the name of the template from which the current resource has been cloned from. | Cluster API | Any Cluster API resource cloned from a template | +| cluster.x-k8s.io/cluster-name | It is set on nodes identifying the name of the cluster the node belongs to. | Cluster API | Nodes | +| cluster.x-k8s.io/cluster-namespace | It is set on nodes identifying the namespace of the cluster the node belongs to. | Cluster API | Nodes | +| cluster.x-k8s.io/delete-machine | It marks control plane and worker nodes that will be given priority for deletion when KCP or a MachineSet scales down.
