Functions

func CreateAPIServerCertAndKeyFiles

func CreateAPIServerCertAndKeyFiles(cfg *kubeadmapi.MasterConfiguration) error

CreateAPIServerCertAndKeyFiles create a new certificate and key files for the apiserver. If the apiserver certificate and key files already exists in the target folder, they are used only if evaluated equal; otherwise an error is returned. It assumes the cluster CA certificate and key files exist in the CertificatesDir.

func CreateAPIServerEtcdClientCertAndKeyFiles

func CreateAPIServerEtcdClientCertAndKeyFiles(cfg *kubeadmapi.MasterConfiguration) error

CreateAPIServerEtcdClientCertAndKeyFiles create a new client certificate for the apiserver calling etcd If the apiserver-etcd-client certificate and key file already exist in the target folder, they are used only if evaluated equal; otherwise an error is returned. It assumes the etcd CA certificate and key file exist in the CertificatesDir

func CreateAPIServerKubeletClientCertAndKeyFiles

func CreateAPIServerKubeletClientCertAndKeyFiles(cfg *kubeadmapi.MasterConfiguration) error

CreateAPIServerKubeletClientCertAndKeyFiles create a new certificate for kubelets calling apiserver. If the apiserver-kubelet-client certificate and key files already exists in the target folder, they are used only if evaluated equals; otherwise an error is returned. It assumes the cluster CA certificate and key files exist in the CertificatesDir.

func CreateCACertAndKeyFiles

func CreateCACertAndKeyFiles(cfg *kubeadmapi.MasterConfiguration) error

CreateCACertAndKeyFiles create a new self signed cluster CA certificate and key files. If the CA certificate and key files already exists in the target folder, they are used only if evaluated equal; otherwise an error is returned.

func CreateEtcdCACertAndKeyFiles

func CreateEtcdCACertAndKeyFiles(cfg *kubeadmapi.MasterConfiguration) error

CreateEtcdCACertAndKeyFiles create a self signed etcd CA certificate and key files. The etcd CA and client certs are used to secure communication between etcd peers and connections to etcd from the API server. This is a separate CA, so that kubernetes client identities cannot connect to etcd directly or peer with the etcd cluster. If the etcd CA certificate and key files already exists in the target folder, they are used only if evaluated equals; otherwise an error is returned.

func CreateEtcdHealthcheckClientCertAndKeyFiles

func CreateEtcdHealthcheckClientCertAndKeyFiles(cfg *kubeadmapi.MasterConfiguration) error

CreateEtcdHealthcheckClientCertAndKeyFiles create a new client certificate for liveness probes to healthcheck etcd If the etcd-healthcheck-client certificate and key file already exist in the target folder, they are used only if evaluated equal; otherwise an error is returned. It assumes the etcd CA certificate and key file exist in the CertificatesDir

func CreateEtcdPeerCertAndKeyFiles

func CreateEtcdPeerCertAndKeyFiles(cfg *kubeadmapi.MasterConfiguration) error

CreateEtcdPeerCertAndKeyFiles create a new certificate and key file for etcd peering. If the etcd peer certificate and key file already exist in the target folder, they are used only if evaluated equal; otherwise an error is returned. It assumes the etcd CA certificate and key file exist in the CertificatesDir

func CreateEtcdServerCertAndKeyFiles

func CreateEtcdServerCertAndKeyFiles(cfg *kubeadmapi.MasterConfiguration) error

CreateEtcdServerCertAndKeyFiles create a new certificate and key file for etcd. If the etcd serving certificate and key file already exist in the target folder, they are used only if evaluated equal; otherwise an error is returned. It assumes the etcd CA certificate and key file exist in the CertificatesDir

func CreateFrontProxyCACertAndKeyFiles

func CreateFrontProxyCACertAndKeyFiles(cfg *kubeadmapi.MasterConfiguration) error

CreateFrontProxyCACertAndKeyFiles create a self signed front proxy CA certificate and key files. Front proxy CA and client certs are used to secure a front proxy authenticator which is used to assert identity without the client cert; This is a separate CA, so that front proxy identities cannot hit the API and normal client certs cannot be used as front proxies. If the front proxy CA certificate and key files already exists in the target folder, they are used only if evaluated equals; otherwise an error is returned.

func CreateFrontProxyClientCertAndKeyFiles

func CreateFrontProxyClientCertAndKeyFiles(cfg *kubeadmapi.MasterConfiguration) error

CreateFrontProxyClientCertAndKeyFiles create a new certificate for proxy server client. If the front-proxy-client certificate and key files already exists in the target folder, they are used only if evaluated equals; otherwise an error is returned. It assumes the front proxy CA certificate and key files exist in the CertificatesDir.

func CreatePKIAssets

func CreatePKIAssets(cfg *kubeadmapi.MasterConfiguration) error

CreatePKIAssets will create and write to disk all PKI assets necessary to establish the control plane. If the PKI assets already exists in the target folder, they are used only if evaluated equal; otherwise an error is returned.

func CreateServiceAccountKeyAndPublicKeyFiles

func CreateServiceAccountKeyAndPublicKeyFiles(cfg *kubeadmapi.MasterConfiguration) error

CreateServiceAccountKeyAndPublicKeyFiles create a new public/private key files for signing service account users. If the sa public/private key files already exists in the target folder, they are used only if evaluated equals; otherwise an error is returned.

func NewAPIServerCertAndKey

func NewAPIServerCertAndKey(cfg *kubeadmapi.MasterConfiguration, caCert *x509.Certificate, caKey *rsa.PrivateKey) (*x509.Certificate, *rsa.PrivateKey, error)

NewAPIServerCertAndKey generate certificate for apiserver, signed by the given CA.

func NewAPIServerEtcdClientCertAndKey

func NewAPIServerEtcdClientCertAndKey(caCert *x509.Certificate, caKey *rsa.PrivateKey) (*x509.Certificate, *rsa.PrivateKey, error)

NewAPIServerEtcdClientCertAndKey generate certificate for the apiservers to connect to etcd securely, signed by the given CA.

func NewAPIServerKubeletClientCertAndKey

func NewAPIServerKubeletClientCertAndKey(caCert *x509.Certificate, caKey *rsa.PrivateKey) (*x509.Certificate, *rsa.PrivateKey, error)

NewAPIServerKubeletClientCertAndKey generate certificate for the apiservers to connect to the kubelets securely, signed by the given CA.

func NewCACertAndKey

func NewCACertAndKey() (*x509.Certificate, *rsa.PrivateKey, error)

NewCACertAndKey will generate a self signed CA.

func NewEtcdCACertAndKey

NewEtcdCACertAndKey generate a self signed etcd CA.

func NewEtcdHealthcheckClientCertAndKey

func NewEtcdHealthcheckClientCertAndKey(caCert *x509.Certificate, caKey *rsa.PrivateKey) (*x509.Certificate, *rsa.PrivateKey, error)

NewEtcdHealthcheckClientCertAndKey generate certificate for liveness probes to healthcheck etcd, signed by the given CA.

func NewEtcdPeerCertAndKey

func NewEtcdPeerCertAndKey(cfg *kubeadmapi.MasterConfiguration, caCert *x509.Certificate, caKey *rsa.PrivateKey) (*x509.Certificate, *rsa.PrivateKey, error)

NewEtcdPeerCertAndKey generate certificate for etcd peering, signed by the given CA.

func NewEtcdServerCertAndKey

func NewEtcdServerCertAndKey(cfg *kubeadmapi.MasterConfiguration, caCert *x509.Certificate, caKey *rsa.PrivateKey) (*x509.Certificate, *rsa.PrivateKey, error)

NewEtcdServerCertAndKey generate certificate for etcd, signed by the given CA.

func NewFrontProxyCACertAndKey

func NewFrontProxyCACertAndKey() (*x509.Certificate, *rsa.PrivateKey, error)

NewFrontProxyCACertAndKey generate a self signed front proxy CA.

func NewFrontProxyClientCertAndKey

func NewFrontProxyClientCertAndKey(frontProxyCACert *x509.Certificate, frontProxyCAKey *rsa.PrivateKey) (*x509.Certificate, *rsa.PrivateKey, error)

NewFrontProxyClientCertAndKey generate certificate for proxy server client, signed by the given front proxy CA.

func NewServiceAccountSigningKey

func NewServiceAccountSigningKey() (*rsa.PrivateKey, error)

NewServiceAccountSigningKey generate public/private key pairs for signing service account tokens.

func UsingExternalCA

func UsingExternalCA(cfg *kubeadmapi.MasterConfiguration) (bool, error)

UsingExternalCA determines whether the user is relying on an external CA. We currently implicitly determine this is the case when both the CA Cert and the front proxy CA Cert are present but the CA Key and front proxy CA Key are not. This allows us to, e.g., skip generating certs or not start the csr signing controller.
