Functions

func Script

func Script(
	cloudConfigUserData []byte,
	hyperkubeImage *imagevector.Image,
	kubernetesVersion string,
	kubeletDataVolume *gardencorev1beta1.DataVolume,
	reloadConfigCommand string,
	units []string,
) (
	[]byte,
	error,
)

Script returns the executor script that applies the downloaded cloud-config user-data.

func Secret

func Secret(name, namespace, poolName string, script []byte) *corev1.Secret

Secret returns a Kubernetes secret object containing the cloud-config user-data executor script.
