ClusterClass is a template which can be used to create managed topologies. Deprecated: This type will be removed in one of the next releases.
4 top-level fields · last changed in Cluster API v1.9.0
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
ClusterClassSpec describes the desired state of the ClusterClass.
controlPlane is a reference to a local struct that holds the details for provisioning the Control Plane for the Cluster.
MachineTemplate defines the metadata and infrastructure information for control plane machines. This field is supported if and only if the control plane provider template referenced above is Machine based and supports setting replicas.
ref is a required reference to a custom resource offered by a provider.
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.

metadata is the metadata applied to the machines of the ControlPlane. At runtime this metadata is merged with the corresponding metadata from the topology. This field is supported if and only if the control plane provider template referenced is Machine based.
annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects. More info: http://kubernetes.io/docs/user-guide/annotations
Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services. More info: http://kubernetes.io/docs/user-guide/labels

infrastructure is a reference to a provider-specific template that holds the details for provisioning infrastructure specific cluster for the underlying provider. The underlying provider is responsible for the implementation of the template to an infrastructure cluster.

machineDeployments is a list of machine deployment classes that can be used to create a set of worker nodes.
class denotes a type of worker node present in the cluster, this name MUST be unique within a ClusterClass and can be referenced in the Cluster to create a managed MachineDeployment.
template is a local struct containing a collection of templates for creation of MachineDeployment objects representing a set of worker nodes.
bootstrap contains the bootstrap template reference to be used for the creation of worker Machines.
