scaleDown is scaling policy for scaling Down.
If not set, the default value is to allow to scale down to minReplicas pods, with a
300 second stabilization window (i.e., the highest recommendation for
the last 300sec is used).
policies
[]object
policies is a list of potential scaling polices which can be used during scaling.
If not set, use the default values:
- For scale up: allow doubling the number of pods, or an absolute change of 4 pods in a 15s window.
- For scale down: allow all pods to be removed in a 15s window.
periodSeconds
integer required
periodSeconds specifies the window of time for which the policy should hold true.
PeriodSeconds must be greater than zero and less than or equal to 1800 (30 min).
format: int32
type
string required
type is used to specify the scaling policy.
value
integer required
value contains the amount of change which is permitted by the policy.
It must be greater than zero
format: int32
selectPolicy
string
selectPolicy is used to specify which policy should be used.
If not set, the default value Max is used.
stabilizationWindowSeconds
integer
stabilizationWindowSeconds is the number of seconds for which past recommendations should be
considered while scaling up or scaling down.
StabilizationWindowSeconds must be greater than or equal to zero and less than or equal to 3600 (one hour).
If not set, use the default values:
- For scale up: 0 (i.e. no stabilization is done).
- For scale down: 300 (i.e. the stabilization window is 300 seconds long).
format: int32
minimum: 0
maximum: 3600
tolerance
object
tolerance is the tolerance on the ratio between the current and desired
metric value under which no updates are made to the desired number of
replicas (e.g. 0.01 for 1%). Must be greater than or equal to zero. If not
set, the default cluster-wide tolerance is applied (by default 10%).
For example, if autoscaling is configured with a memory consumption target of 100Mi,
and scale-down and scale-up tolerances of 5% and 1% respectively, scaling will be
triggered when the actual consumption falls below 95Mi or exceeds 101Mi.
This is an alpha field and requires enabling the HPAConfigurableTolerance
feature gate.
