func ResolveCSRInitImage 

func ResolveCSRInitImage(inst *operatorv1.InstallationSpec, is *operatorv1.ImageSet) (string, error)

ResolveCsrInitImage resolves the image needed for the CSR init image taking into account the specified ImageSet

Types

type CertificateInterface 

type CertificateInterface interface {
	GetIssuer() CertificateInterface
	GetCertificatePEM() []byte
	GetName() string
	GetNamespace() string
}

CertificateInterface wraps the certificate. Combine this with a TrustedBundle, to mount a trusted certificate bundle to a pod.

func NewCertificate 

func NewCertificate(name, ns string, pem []byte, issuer CertificateInterface) CertificateInterface

NewCertificate creates a new certificate.

type KeyPair 

type KeyPair struct {
	CSRImage  string
	Name      string
	Namespace string
	// Golang's x509 package uses the 'any' type for all private and public keys. See x509.CreateCertificate() for more.
	PrivateKey     any
	PrivateKeyPEM  []byte
	CertificatePEM []byte
	ClusterDomain  string
	*operatorv1.CertificateManagement
	DNSNames []string
	Issuer   KeyPairInterface

	// OriginalSecret maintains a copy of the secret that the KeyPair was created from.
	OriginalSecret *corev1.Secret
}

func (*KeyPair) BYO 

func (k *KeyPair) BYO() bool

BYO returns true if this KeyPair was provided by the user. If BYO is true, UseCertificateManagement is false.

func (*KeyPair) GetCertificatePEM 

func (k *KeyPair) GetCertificatePEM() []byte

func (*KeyPair) GetIssuer 

func (k *KeyPair) GetIssuer() CertificateInterface

func (*KeyPair) GetName 

func (k *KeyPair) GetName() string

func (*KeyPair) GetNamespace added in v1.32.0 

func (k *KeyPair) GetNamespace() string

func (*KeyPair) HashAnnotationKey 

func (k *KeyPair) HashAnnotationKey() string

func (*KeyPair) HashAnnotationValue 

func (k *KeyPair) HashAnnotationValue() string

func (*KeyPair) InitContainer 

func (k *KeyPair) InitContainer(namespace string) corev1.Container

InitContainer contains an init container for making a CSR. is only applicable when certificate management is enabled.

func (*KeyPair) Secret 

func (k *KeyPair) Secret(namespace string) *corev1.Secret

func (*KeyPair) UseCertificateManagement 

func (k *KeyPair) UseCertificateManagement() bool

UseCertificateManagement is true if this secret is not BYO and certificate management is used to provide the a pair to a pod.

func (*KeyPair) Volume 

func (k *KeyPair) Volume() corev1.Volume

func (*KeyPair) VolumeMount 

func (k *KeyPair) VolumeMount(osType rmeta.OSType) corev1.VolumeMount

func (*KeyPair) VolumeMountCertificateFilePath 

func (k *KeyPair) VolumeMountCertificateFilePath() string

func (*KeyPair) VolumeMountKeyFilePath 

func (k *KeyPair) VolumeMountKeyFilePath() string

type KeyPairInterface 

type KeyPairInterface interface {
	// UseCertificateManagement returns true if this key pair was not user provided and certificate management has been configured.
	UseCertificateManagement() bool
	// BYO returns true if this KeyPair was provided by the user. If BYO is true, UseCertificateManagement is false.
	BYO() bool
	InitContainer(namespace string) corev1.Container
	VolumeMount(osType meta.OSType) corev1.VolumeMount
	VolumeMountKeyFilePath() string
	VolumeMountCertificateFilePath() string
	Volume() corev1.Volume
	Secret(namespace string) *corev1.Secret
	HashAnnotationKey() string
	HashAnnotationValue() string
	CertificateInterface
}

KeyPairInterface wraps a Secret object that contains a private key and a certificate. Whether CertificateManagement is configured or not, KeyPair returns the right InitContainer, VolumeMount or Volume (when applicable).

func NewKeyPair 

func NewKeyPair(secret *corev1.Secret, dnsNames []string, clusterDomain string) KeyPairInterface

NewKeyPair returns a KeyPair, which wraps a Secret object that contains a private key and a certificate. Whether certificate management is configured or not, KeyPair returns the right InitContainer, Volumemount or Volume (when applicable).

type TrustedBundle 

type TrustedBundle interface {
	MountPath() string
	ConfigMap(namespace string) *corev1.ConfigMap
	HashAnnotations() map[string]string
