func GetPodQoSClass ¶

func GetPodQoSClass(pod *corev1.Pod) corev1.PodQOSClass

func LimitForRatio ¶ added in v0.14.0

func LimitForRatio(
	name corev1.ResourceName,
	request resource.Quantity,
	ratio resource.Quantity,
) (resource.Quantity, error)

LimitForRatio calculates request * ratio without floating-point arithmetic. The result is rounded down so it never exceeds the configured maximum ratio.

func PodLevelResourceSupported ¶ added in v0.14.0

func PodLevelResourceSupported(name corev1.ResourceName) bool

PodLevelResourceSupported reports whether Kubernetes permits the resource name in Pod-level resource requirements.

func RatioSupportedResource ¶ added in v0.14.0

func RatioSupportedResource(name corev1.ResourceName) bool

RatioSupportedResource reports whether Capsule can safely calculate a limit-to-request ratio for the resource. CPU is rounded down to milliCPU; byte-based resources are rounded down to whole bytes.
