Constants

View Source 
const DefaultCPUUtilization = 80

DefaultCPUUtilization is the default value for CPU utilization, provided no other metrics are present. This is here because it's used by both the v2beta1 defaulting logic, and the pseudo-defaulting done in v1 conversion.

Types

type ConditionStatus added in v1.7.0 

type ConditionStatus string

ConditionStatus indicates the status of a condition (true, false, or unknown). 

const (
	ConditionTrue    ConditionStatus = "True"
	ConditionFalse   ConditionStatus = "False"
	ConditionUnknown ConditionStatus = "Unknown"
)

These are valid condition statuses. "ConditionTrue" means a resource is in the condition; "ConditionFalse" means a resource is not in the condition; "ConditionUnknown" means kubernetes can't decide if a resource is in the condition or not. In the future, we could add other intermediate conditions, e.g. ConditionDegraded.
