func ValidateV1Beta1SnapshotContent ¶ added in v4.1.0

func ValidateV1Beta1SnapshotContent(snapcontent *crdv1beta1.VolumeSnapshotContent) error

ValidateV1Beta1SnapshotContent performs additional strict validation. Do NOT rely on this function to fully validate snapshot content objects. This function will only check the additional rules provided by the webhook.

func ValidateV1Snapshot ¶ added in v4.1.0

func ValidateV1Snapshot(snapshot *crdv1.VolumeSnapshot) error

ValidateV1Snapshot performs additional strict validation. Do NOT rely on this function to fully validate snapshot objects. This function will only check the additional rules provided by the webhook.

func ValidateV1SnapshotContent ¶ added in v4.1.0

func ValidateV1SnapshotContent(snapcontent *crdv1.VolumeSnapshotContent) error

ValidateV1SnapshotContent performs additional strict validation. Do NOT rely on this function to fully validate snapshot content objects. This function will only check the additional rules provided by the webhook.

Types ¶

type CertWatcher ¶

type CertWatcher struct {
	sync.Mutex
	// contains filtered or unexported fields
}

CertWatcher watches certificate and key files for changes. When either file changes, it reads and parses both and calls an optional callback with the new certificate.

func NewCertWatcher ¶

func NewCertWatcher(certPath, keyPath string) (*CertWatcher, error)

NewCertWatcher returns a new CertWatcher watching the given certificate and key.

func (*CertWatcher) GetCertificate ¶

func (cw *CertWatcher) GetCertificate(_ *tls.ClientHelloInfo) (*tls.Certificate, error)

GetCertificate fetches the currently loaded certificate, which may be nil.

func (*CertWatcher) ReadCertificate ¶

func (cw *CertWatcher) ReadCertificate() error

ReadCertificate reads the certificate and key files from disk, parses them, and updates the current certificate on the watcher. If a callback is set, it is invoked with the new certificate.

func (*CertWatcher) Start ¶

func (cw *CertWatcher) Start(ctx context.Context) error

Start starts the watch on the certificate and key files.

func (*CertWatcher) Watch ¶

func (cw *CertWatcher) Watch()

Watch reads events from the watcher's channel and reacts to changes.

type Config ¶

type Config struct {
	CertFile string
	KeyFile  string
}

Config contains the server (the webhook) cert and key.
