Types ¶

// The cluster name.
// Optional, this will be overridden by --name / KIND_CLUSTER_NAME
Name string `yaml:"name,omitempty" json:"name,omitempty"`
// Nodes contains the list of nodes defined in the `kind` Cluster
// If unset this will default to a single control-plane node
// Note that if more than one control plane is specified, an external
// control plane load balancer will be provisioned implicitly

// Networking contains cluster wide network settings
Networking Networking `yaml:"networking,omitempty" json:"networking,omitempty"`
// FeatureGates contains a map of Kubernetes feature gates to whether they

//
// Use this to enable alpha APIs.
RuntimeConfig map[string]string `yaml:"runtimeConfig,omitempty" json:"runtimeConfig,omitempty"`
// KubeadmConfigPatches are applied to the generated kubeadm config as
// merge patches. The `kind` field must match the target object, and
// if `apiVersion` is specified it will only be applied to matching objects.
//
// This should be an inline yaml blob-string
//
// https://tools.ietf.org/html/rfc7386
