APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

ObjectMeta is metadata that all persisted resources must have, which includes all objects users must create.

spec is the desired state of Cluster.

status is the observed state of Cluster.

availabilityGates specifies additional conditions to include when evaluating Cluster Available condition.

If this field is not defined and the Cluster implements a managed topology, availabilityGates from the corresponding ClusterClass will be used, if any.

NOTE: this field is considered only for computing v1beta2 conditions.

paused can be used to prevent controllers from processing the Cluster and all its associated objects.

topology encapsulates the topology for the cluster. NOTE: It is required to enable the ClusterTopology feature gate flag to activate managed topologies support; this feature is highly experimental, and parts of it might still be not implemented.

conditionType refers to a condition with matching type in the Cluster's condition list. If the conditions doesn't exist, it will be treated as unknown. Note: Both Cluster API conditions or conditions added by 3rd party controllers can be used as availability gates.

polarity of the conditionType specified in this availabilityGate. Valid values are Positive, Negative and omitted. When omitted, the default behaviour will be Positive. A positive polarity means that the condition should report a true status under normal conditions. A negative polarity means that the condition should report a false status under normal conditions.

API version of the referent.

If referring to a piece of an object instead of an entire object, this string should contain a valid JSON/Go field access statement, such as desiredState.manifest.containers[2]. For example, if the object reference is to a container within a pod, this would take on a value like: "spec.containers{name}" (where "name" refers to the name of the container that triggered the event) or if no container name is specified "spec.containers[2]" (container with index 2 in this pod). This syntax is chosen only to have some well-defined way of referencing a part of an object.

class is the name of the ClusterClass object to create the topology.

classNamespace is the namespace of the ClusterClass that should be used for the topology. If classNamespace is empty or not set, it is defaulted to the namespace of the Cluster object. classNamespace must be a valid namespace name and because of that be at most 63 characters in length and it must consist only of lower case alphanumeric characters or hyphens (-), and must start and end with an alphanumeric character.

controlPlane describes the cluster control plane.

rolloutAfter performs a rollout of the entire cluster one component at a time, control plane first and then machine deployments.

Deprecated: This field has no function and is going to be removed in the next apiVersion.

variables can be used to customize the Cluster through patches. They must comply to the corresponding VariableClasses defined in the ClusterClass.

version is the Kubernetes version of the cluster.

workers encapsulates the different constructs that form the worker nodes for the cluster.

machineHealthCheck allows to enable, disable and override the MachineHealthCheck configuration in the ClusterClass for this control plane.

metadata is the metadata applied to the ControlPlane and the Machines of the ControlPlane if the ControlPlaneTemplate referenced by the ClusterClass is machine based. If not, it is applied only to the ControlPlane. At runtime this metadata is merged with the corresponding metadata from the ClusterClass.

nodeDeletionTimeout defines how long the controller will attempt to delete the Node that the Machine hosts after the Machine is marked for deletion. A duration of 0 will retry deletion indefinitely. Defaults to 10 seconds.

nodeDrainTimeout is the total amount of time that the controller will spend on draining a node. The default value is 0, meaning that the node can be drained without any time limitations. NOTE: NodeDrainTimeout is different from kubectl drain --timeout

nodeVolumeDetachTimeout is the total amount of time that the controller will spend on waiting for all volumes to be detached. The default value is 0, meaning that the volumes can be detached without any time limitations.

readinessGates specifies additional conditions to include when evaluating Machine Ready condition.

This field can be used e.g. to instruct the machine controller to include in the computation for Machine's ready computation a condition, managed by an external controllers, reporting the status of special software/hardware installed on the Machine.

If this field is not defined, readinessGates from the corresponding ControlPlaneClass will be used, if any.

NOTE: This field is considered only for computing v1beta2 conditions. NOTE: Specific control plane provider implementations might automatically extend the list of readinessGates; e.g. the kubeadm control provider adds ReadinessGates for the APIServerPodHealthy, SchedulerPodHealthy conditions, etc.

replicas is the number of control plane nodes. If the value is nil, the ControlPlane object is created without the number of Replicas and it's assumed that the control plane controller does not implement support for this field. When specified against a control plane provider that lacks support for this field, this value will be ignored.

variables can be used to customize the ControlPlane through patches.

enable controls if a MachineHealthCheck should be created for the target machines.

If false: No MachineHealthCheck will be created.

If not set(default): A MachineHealthCheck will be created if it is defined here or in the associated ClusterClass. If no MachineHealthCheck is defined then none will be created.

If true: A MachineHealthCheck is guaranteed to be created. Cluster validation will block if enable is true and no MachineHealthCheck definition is available.

maxUnhealthy specifies the maximum number of unhealthy machines allowed. Any further remediation is only allowed if at most "maxUnhealthy" machines selected by "selector" are not healthy.

nodeStartupTimeout allows to set the maximum time for MachineHealthCheck to consider a Machine unhealthy if a corresponding Node isn't associated through a Spec.ProviderID field.

The duration set in this field is compared to the greatest of:

• Cluster's infrastructure ready condition timestamp (if and when available)
• Control Plane's initialized condition timestamp (if and when available)
• Machine's infrastructure ready condition timestamp (if and when available)
• Machine's metadata creation timestamp

Defaults to 10 minutes. If you wish to disable this feature, set the value explicitly to 0.

remediationTemplate is a reference to a remediation template provided by an infrastructure provider.

This field is completely optional, when filled, the MachineHealthCheck controller creates a new object from the template referenced and hands off remediation of the machine to a controller that lives outside of Cluster API.

unhealthyConditions contains a list of the conditions that determine whether a node is considered unhealthy. The conditions are combined in a logical OR, i.e. if any of the conditions is met, the node is unhealthy.

unhealthyRange specifies the range of unhealthy machines allowed. Any further remediation is only allowed if the number of machines selected by "selector" as not healthy is within the range of "unhealthyRange". Takes precedence over maxUnhealthy. Eg. "[3-5]" - This means that remediation will be allowed only when: (a) there are at least 3 unhealthy machines (and) (b) there are at most 5 unhealthy machines

status of the condition, one of True, False, Unknown.

timeout is the duration that a node must be in a given status for, after which the node is considered unhealthy. For example, with a value of "1h", the node must match the status for at least 1 hour before being considered unhealthy.

type of Node condition

conditionType refers to a condition with matching type in the Machine's condition list. If the conditions doesn't exist, it will be treated as unknown. Note: Both Cluster API conditions or conditions added by 3rd party controllers can be used as readiness gates.

polarity of the conditionType specified in this readinessGate. Valid values are Positive, Negative and omitted. When omitted, the default behaviour will be Positive. A positive polarity means that the condition should report a true status under normal conditions. A negative polarity means that the condition should report a false status under normal conditions.

remediation controls the strategy of remediating unhealthy machines and how remediating operations should occur during the lifecycle of the dependant MachineSets.

rollingUpdate is the rolling update config params. Present only if MachineDeploymentStrategyType = RollingUpdate.

type of deployment. Allowed values are RollingUpdate and OnDelete. The default is RollingUpdate.

maxInFlight determines how many in flight remediations should happen at the same time.

Remediation only happens on the MachineSet with the most current revision, while older MachineSets (usually present during rollout operations) aren't allowed to remediate.

Note: In general (independent of remediations), unhealthy machines are always prioritized during scale down operations over healthy ones.

MaxInFlight can be set to a fixed number or a percentage. Example: when this is set to 20%, the MachineSet controller deletes at most 20% of the desired replicas.

If not set, remediation is limited to all machines (bounded by replicas) under the active MachineSet's management.

deletePolicy defines the policy used by the MachineDeployment to identify nodes to delete when downscaling. Valid values are "Random", "Newest", "Oldest" When no value is supplied, the default DeletePolicy of MachineSet is used

maxSurge is the maximum number of machines that can be scheduled above the desired number of machines. Value can be an absolute number (ex: 5) or a percentage of desired machines (ex: 10%). This can not be 0 if MaxUnavailable is 0. Absolute number is calculated from percentage by rounding up. Defaults to 1. Example: when this is set to 30%, the new MachineSet can be scaled up immediately when the rolling update starts, such that the total number of old and new machines do not exceed 130% of desired machines. Once old machines have been killed, new MachineSet can be scaled up further, ensuring that total number of machines running at any time during the update is at most 130% of desired machines.

maxUnavailable is the maximum number of machines that can be unavailable during the update. Value can be an absolute number (ex: 5) or a percentage of desired machines (ex: 10%). Absolute number is calculated from percentage by rounding down. This can not be 0 if MaxSurge is 0. Defaults to 0. Example: when this is set to 30%, the old MachineSet can be scaled down to 70% of desired machines immediately when the rolling update starts. Once new machines are ready, old MachineSet can be scaled down further, followed by scaling up the new MachineSet, ensuring that the total number of machines available at all times during the update is at least 70% of desired machines.

overrides can be used to override Cluster level variables.
