Functions

func Get

func Get(ctx context.Context, c client.Reader, cluster client.ObjectKey, purpose Purpose) (*corev1.Secret, error)

Get retrieves the specified Secret (if any) from the given cluster name and namespace.

func GetFromNamespacedName

func GetFromNamespacedName(ctx context.Context, c client.Reader, clusterName client.ObjectKey, purpose Purpose) (*corev1.Secret, error)

GetFromNamespacedName retrieves the specified Secret (if any) from the given cluster name and namespace.

func Name

func Name(cluster string, suffix Purpose) string

Name returns the name of the secret for a cluster.

Types

type Certificate

type Certificate struct {
	Generated         bool
	External          bool
	Purpose           Purpose
	KeyPair           *certs.KeyPair
	CertFile, KeyFile string
}

Certificate represents a single certificate CA.

func (*Certificate) AsFiles

func (c *Certificate) AsFiles() []bootstrapv1.File

AsFiles converts the certificate to a slice of Files that may have 0, 1 or 2 Files.

func (*Certificate) AsSecret

func (c *Certificate) AsSecret(clusterName client.ObjectKey, owner metav1.OwnerReference) *corev1.Secret

AsSecret converts a single certificate into a Kubernetes secret.

func (*Certificate) Hashes

func (c *Certificate) Hashes() ([]string, error)

Hashes hashes all the certificates stored in a CA certificate.

type Certificates

type Certificates []*Certificate

Certificates are the certificates necessary to bootstrap a cluster.

func NewCertificatesForInitialControlPlane

func NewCertificatesForInitialControlPlane(config *v1beta1.ClusterConfiguration) Certificates

NewCertificatesForInitialControlPlane returns a list of certificates configured for a control plane node

func NewCertificatesForJoiningControlPlane

func NewCertificatesForJoiningControlPlane() Certificates

NewCertificatesForJoiningControlPlane gets any certs that exist and writes them to disk

Deprecated: this method is deprecated in favor of NewControlPlaneJoinCerts that provides full support for the external etcd scenario.

func NewCertificatesForWorker

func NewCertificatesForWorker(caCertPath string) Certificates

NewCertificatesForWorker return an initialized but empty set of CA certificates needed to bootstrap a cluster.

func NewControlPlaneJoinCerts

func NewControlPlaneJoinCerts(config *v1beta1.ClusterConfiguration) Certificates

NewControlPlaneJoinCerts gets any certs that exist and writes them to disk

func (Certificates) AsFiles

func (c Certificates) AsFiles() []bootstrapv1.File

AsFiles converts a slice of certificates into bootstrap files.

func (Certificates) EnsureAllExist

func (c Certificates) EnsureAllExist() error

EnsureAllExist ensure that there is some data present for every certificate

func (Certificates) Generate

func (c Certificates) Generate() error

Generate will generate any certificates that do not have KeyPair data.

func (Certificates) GetByPurpose

func (c Certificates) GetByPurpose(purpose Purpose) *Certificate

GetByPurpose returns a certificate by the given name. This could be removed if we use a map instead of a slice to hold certificates, however other code becomes more complex.

func (Certificates) Lookup

func (c Certificates) Lookup(ctx context.Context, ctrlclient client.Client, clusterName client.ObjectKey) error

Lookup looks up each certificate from secrets and populates the certificate with the secret data.

func (Certificates) LookupOrGenerate

func (c Certificates) LookupOrGenerate(ctx context.Context, ctrlclient client.Client, clusterName client.ObjectKey, owner metav1.OwnerReference) error

LookupOrGenerate is a convenience function that wraps cluster bootstrap certificate behavior.

func (Certificates) SaveGenerated

func (c Certificates) SaveGenerated(ctx context.Context, ctrlclient client.Client, clusterName client.ObjectKey, owner metav1.OwnerReference) error

SaveGenerated will save any certificates that have been generated as Kubernetes secrets.

type Purpose

type Purpose string

Purpose is the name to append to the secret generated for a cluster.

func ParseSecretName

func ParseSecretName(name string) (string, Purpose, error)

ParseSecretName return the cluster name and the suffix Purpose in name is a valid cluster secrets, otherwise it return error.
