func Rotate(strategy rotationStrategy) GenerateOption

Rotate returns a function which sets the 'RotationStrategy' field to the specified value.

func SignedByCA 

func SignedByCA(name string, opts ...SignedByCAOption) GenerateOption

SignedByCA returns a function which sets the 'SigningCA' field in case the ConfigInterface provided to the Generate request is a CertificateSecretConfig. Additionally, in such case it stores a checksum of the signing CA in the options.

func Validity added in v1.44.0 

func Validity(v time.Duration) GenerateOption

Validity returns a function which sets the 'Validity' field to the provided value. Note that the value is ignored in case Generate is called with a certificate secret configuration.

type GenerateOptions 

type GenerateOptions struct {
	// Persist specifies whether the 'persist=true' label should be added to the secret resources.
	Persist bool
	// RotationStrategy specifies how the secret should be rotated in case it needs to get rotated.
	RotationStrategy rotationStrategy
	// IgnoreOldSecrets specifies whether old secrets should be dropped.
	IgnoreOldSecrets bool
	// IgnoreOldSecretsAfter specifies that old secrets should be dropped once a given duration after rotation has passed.
	IgnoreOldSecretsAfter *time.Duration
	// Validity specifies for how long the secret should be valid.
	Validity time.Duration
	// RenewAfterValidityPercentage sets the percentage of the validity when the certificate should be renewed.
	// The effective check for renewal is after the given percentage of validity or 10d before the end of validity.
	// Zero value means the default percentage is used (80%).
	RenewAfterValidityPercentage int
	// IgnoreConfigChecksumForCASecretName specifies whether the secret config checksum should be ignored when
	// computing the secret name for CA secrets.

	Reader

	// Cleanup deletes no longer required secrets. No longer required secrets are those still existing in the system
