How do I serialize CRDs with kubebuilder?

In Kubebuilder, custom resource definitions (CRDs) are serialized using Go structs. The serialization process converts the struct into a format that can be understood by the Kubernetes API server. This allows custom resources to be easily maintained and utilized within the Kubernetes ecosystem.

To serialize CRDs, you often define your custom resource types by creating Go structs and using annotations to specify how they should be handled when serialized into the Kubernetes API.

Here is an example of how to serialize a CRD in Kubebuilder:

// +kubebuilder:object:root=true // +kubebuilder:subresource:status // MyCustomResource is the Schema for the mycustomresources API type MyCustomResource struct { metav1.TypeMeta `json:",inline"` metav1.ObjectMeta `json:"metadata,omitempty"` Spec MyCustomResourceSpec `json:"spec,omitempty"` Status MyCustomResourceStatus `json:"status,omitempty"` } // MyCustomResourceSpec defines the desired state of MyCustomResource type MyCustomResourceSpec struct { // Define your spec fields here } // MyCustomResourceStatus defines the observed state of MyCustomResource type MyCustomResourceStatus struct { // Define your status fields here }
