Struct HorizontalPodAutoscalerSpec

pub struct HorizontalPodAutoscalerSpec {
    pub behavior: Option<HorizontalPodAutoscalerBehavior>,
    pub max_replicas: i32,
    pub metrics: Option<Vec<MetricSpec>>,
    pub min_replicas: Option<i32>,
    pub scale_target_ref: CrossVersionObjectReference,
}

HorizontalPodAutoscalerSpec describes the desired functionality of the HorizontalPodAutoscaler.

Fields

behavior: Option<HorizontalPodAutoscalerBehavior>

behavior configures the scaling behavior of the target in both Up and Down directions (scaleUp and scaleDown fields respectively). If not set, the default HPAScalingRules for scale up and scale down are used.

max_replicas: i32

maxReplicas is the upper limit for the number of replicas to which the autoscaler can scale up. It cannot be less that minReplicas.

metrics: Option<Vec<MetricSpec>>

metrics contains the specifications for which to use to calculate the desired replica count (the maximum replica count across all metrics will be used). The desired replica count is calculated multiplying the ratio between the target value and the current value by the current number of pods. Ergo, metrics used must decrease as the pod count is increased, and vice-versa. See the individual metric source types for more information about how each type of metric must respond. If not set, the default metric will be set to 80% average CPU utilization.

min_replicas: Option<i32>

minReplicas is the lower limit for the number of replicas to which the autoscaler can scale down. It defaults to 1 pod. minReplicas is allowed to be 0 if the alpha feature gate HPAScaleToZero is enabled and at least one Object or External metric is configured. Scaling is active as long as at least one metric value is available.

scale_target_ref: CrossVersionObjectReference

scaleTargetRef points to the target resource to scale, and is used to the pods for which metrics should be collected, as well as to actually change the replica count.

Trait Implementations

impl Clone for HorizontalPodAutoscalerSpec

fn clone(&self) -> HorizontalPodAutoscalerSpec

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HorizontalPodAutoscalerSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DeepMerge for HorizontalPodAutoscalerSpec

fn merge_from(&mut self, other: Self)

Merge other into self.

impl Default for HorizontalPodAutoscalerSpec

fn default() -> HorizontalPodAutoscalerSpec

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HorizontalPodAutoscalerSpec

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for HorizontalPodAutoscalerSpec

fn eq(&self, other: &HorizontalPodAutoscalerSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for HorizontalPodAutoscalerSpec

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
