Types

type BaseTrait

type BaseTrait struct {

type Comparable interface {
	Matches(Trait) bool
}

type ComparableTrait added in v1.7.0

type ComparableTrait interface {
	Trait
	Comparable

type ControllerStrategy

type ControllerStrategy string

ControllerStrategy is used to determine the kind of controller that needs to be created for the integration.

const (
	ControllerStrategyDeployment     ControllerStrategy = "deployment"
	ControllerStrategyKnativeService ControllerStrategy = "knative-service"
	ControllerStrategyCronJob        ControllerStrategy = "cron-job"

	DefaultControllerStrategy = ControllerStrategyDeployment
)

List of controller strategies.

type ControllerStrategySelector

type ControllerStrategySelector interface {
