func GetEtcdAltNames ¶
func GetEtcdAltNames(cfg *kubeadmapi.InitConfiguration) (*certutil.AltNames, error)
GetEtcdAltNames builds an AltNames object for generating the etcd server certificate. `advertise address` and localhost are included in the SAN since this is the interfaces the etcd static pod listens on. The user can override the listen address with `Etcd.ExtraArgs` and add SANs with `Etcd.ServerCertSANs`.
func GetEtcdPeerAltNames ¶
func GetEtcdPeerAltNames(cfg *kubeadmapi.InitConfiguration) (*certutil.AltNames, error)
GetEtcdPeerAltNames builds an AltNames object for generating the etcd peer certificate. Hostname and `API.AdvertiseAddress` are included if the user chooses to promote the single node etcd cluster into a multi-node one (stacked etcd). The user can override the listen address with `Etcd.ExtraArgs` and add SANs with `Etcd.PeerCertSANs`.
func HasServerAuth ¶
func HasServerAuth(cert *x509.Certificate) bool
HasServerAuth returns true if the given certificate is a ServerAuth
func NewCSR ¶
func NewCSR(cfg CertConfig, key crypto.Signer) (*x509.CertificateRequest, error)

func NewCSRAndKey ¶
func NewCSRAndKey(config *CertConfig) (*x509.CertificateRequest, crypto.Signer, error)
NewCSRAndKey generates a new key and CSR and that could be signed to create the given certificate
func NewCertAndKey ¶
func NewCertAndKey(caCert *x509.Certificate, caKey crypto.Signer, config *CertConfig) (*x509.Certificate, crypto.Signer, error)
NewCertAndKey creates new certificate and key by passing the certificate authority certificate and key
func NewCertificateAuthority ¶
func NewCertificateAuthority(config *CertConfig) (*x509.Certificate, crypto.Signer, error)
