Types

type Kubeadm

type Kubeadm struct {
	ContainerRuntime string `yaml:"containerRuntime,omitempty"`
	Configuration    string `yaml:"configuration,omitempty"`
	Init             bool   `yaml:"init,omitempty"`
}

Kubeadm describes the set of configuration options available for kubeadm.

type Kubelet

type KubernetesSecurity

type KubernetesSecurity struct {
	CA *x509.PEMEncodedCertificateAndKey `yaml:"ca"`
}

type Networking

type Networking struct {
	OS         struct{} `yaml:"os"`
	Kubernetes struct{} `yaml:"kubernetes"`
}
