CertificateMap is a flat map of certificates, keyed by Name.

func (CertificateMap) CertTree 

func (m CertificateMap) CertTree() (CertificateTree, error)

CertTree returns a one-level-deep tree, mapping a CA cert to an array of certificates that should be signed by it.

type CertificateTree 

type CertificateTree map[*KubeadmCert]Certificates

CertificateTree is represents a one-level-deep tree, mapping a CA to the certs that depend on it.

type Certificates 

type Certificates []*KubeadmCert

Certificates is a list of Certificates that Kubeadm should create.

func GetCertsWithoutEtcd 

func GetCertsWithoutEtcd() Certificates

GetCertsWithoutEtcd returns all of the certificates kubeadm needs when etcd is hosted externally.

func GetDefaultCertList 

func GetDefaultCertList() Certificates

GetDefaultCertList returns all of the certificates kubeadm requires to function.

func (Certificates) AsMap 

func (c Certificates) AsMap() CertificateMap

AsMap returns the list of certificates as a map, keyed by name.

type KubeadmCert

	// contains filtered or unexported fields
}

KubeadmCert represents a certificate that Kubeadm will create to function properly.

func (*KubeadmCert) CreateAsCA 

func (k *KubeadmCert) CreateAsCA(ic *kubeadmv1beta2.WarpperConfiguration) (*x509.Certificate, crypto.Signer, error)

CreateAsCA creates a certificate authority, writing the files to disk and also returning the created CA so it can be used to sign child certs.

func (*KubeadmCert) CreateFromCA 

func (k *KubeadmCert) CreateFromCA(ic *kubeadmv1beta2.WarpperConfiguration, caCert *x509.Certificate, caKey crypto.Signer) error
