	// contains filtered or unexported fields
}

Kubeadm describes the set of configuration options available for kubeadm.

func (*Kubeadm) MarshalYAML

func (kdm *Kubeadm) MarshalYAML() (interface{}, error)

MarshalYAML implements the yaml.Marshaler interface.

func (*Kubeadm) UnmarshalYAML

func (kdm *Kubeadm) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements the yaml.Unmarshaler interface.

type Kubelet

type Kubelet struct {
	CommonServiceOptions `yaml:",inline"`
}

Kubelet describes the configuration of the kubelet service.

type KubernetesSecurity

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

KubernetesSecurity represents the set of security options specific to Kubernetes.

type Networking

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

Networking represents the set of options available to configure networking.

type OSD

type OSD struct {
	CommonServiceOptions `yaml:",inline"`
}

OSD describes the configuration of the osd service.

type OSSecurity

type OSSecurity struct {
	CA       *x509.PEMEncodedCertificateAndKey `yaml:"ca"`
	Identity *x509.PEMEncodedCertificateAndKey `yaml:"identity"`
}
