Functions ¶
func NewFakeClientWrapper ¶ added in v0.1.6
func NewFakeClientWrapper(c client.Client) client.Client
func NewPVCAutoresizer ¶
func NewPVCAutoresizer(mc MetricsClient, c client.Client, log logr.Logger, interval time.Duration, recorder record.EventRecorder) manager.Runnable
NewPVCAutoresizer returns a new pvcAutoresizer struct
func PvcStorageLimit ¶ added in v0.7.0
func PvcStorageLimit(pvc *corev1.PersistentVolumeClaim) (resource.Quantity, error)

Types ¶
type MetricsClient ¶
type MetricsClient interface {
// GetMetrics returns volume stats metrics of PVCs
//
// The volume stats consist of available bytes, capacity bytes, available inodes and capacity
// inodes. This method returns volume stats for a PVC only if all four metrics of the PVC was
// retrieved from the metrics source.
GetMetrics(ctx context.Context) (map[types.NamespacedName]*VolumeStats, error)
}
MetricsClient is an interface for getting metrics
func NewPrometheusClient ¶
func NewPrometheusClient(url string) (MetricsClient, error)
NewPrometheusClient returns a new prometheusClient
type VolumeStats ¶
type VolumeStats struct {
AvailableBytes int64
CapacityBytes int64
AvailableInodeSize int64
CapacityInodeSize int64
}
VolumeStats is a struct containing metrics used by pvc-autoresizer
