Types

type Cluster

type Cluster struct {
	TypeMeta `yaml:",inline"`

	// The cluster name.
	// Optional, this will be overridden by --name / KIND_CLUSTER_NAME
	Name string `yaml:"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
	Nodes []Node `yaml:"nodes,omitempty"`

	// Networking contains cluster wide network settings
	Networking Networking `yaml:"networking,omitempty"`

	// FeatureGates contains a map of Kubernetes feature gates to whether they
	// are enabled. The feature gates specified here are passed to all Kubernetes components as flags or in config.

	FeatureGates map[string]bool `yaml:"featureGates,omitempty"`

	// RuntimeConfig Keys and values are translated into --runtime-config values for kube-apiserver, separated by commas.
	//
	// Use this to enable alpha APIs.
	RuntimeConfig map[string]string `yaml:"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
	//
	// The cluster-level patches are applied before the node-level patches.

	// apiVersion: group+"/"+version
	//
	// Name and Namespace are now ignored, but the fields continue to exist for
	// backwards compatibility of parsing the config. The name of the generated
	// config was/is always fixed as is the namespace so these fields have
	// always been a no-op.

type Mount

type Mount struct {

	// This is potentially useful for remote hosts, BUT it means when the container
