Overview

Inspired by https://github.com/knative/pkg/tree/97c7258e3a98b81459936bc7a29dc6a9540fa357/apis, but we chose to diverge due to the unacceptably large dependency closure of knative/pkg.

var ConditionCount = conditionCountMetric("", pmetrics.LabelGroup, pmetrics.LabelKind)

Cardinality is limited to # objects * # conditions

var ConditionCurrentStatusSeconds = conditionCurrentStatusSecondsMetric("", pmetrics.LabelGroup, pmetrics.LabelKind)

Cardinality is limited to # objects * # conditions NOTE: This metric is based on a requeue so it won't show the current status seconds with extremely high accuracy. This metric is useful for aggregations. If you need a high accuracy metric, use operator_status_condition_last_transition_time_seconds

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new Condition.

func (*Condition) DeepCopyInto 

func (in *Condition) DeepCopyInto(out *Condition)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

func (*Condition) GetStatus

type ConditionSet 

type ConditionSet struct {
	ConditionTypes
	// contains filtered or unexported fields
}

ConditionSet provides methods for evaluating Conditions. +k8s:deepcopy-gen=false

func (ConditionSet) Clear 

func (c ConditionSet) Clear(t string) error

Clear removes the independent condition that matches the ConditionType Not implemented for dependent conditions

func (ConditionSet) Get 

func (c ConditionSet) Get(t string) *Condition

Get finds and returns the Condition that matches the ConditionType previously set on Conditions.

func (ConditionSet) IsDependentCondition 

func (c ConditionSet) IsDependentCondition(t string) bool

func (ConditionSet) IsTrue 

func (c ConditionSet) IsTrue(conditionTypes ...string) bool

IsTrue returns true if all condition types are true.

func (ConditionSet) List 

func (c ConditionSet) List() []Condition

func (ConditionSet) Root 

func (c ConditionSet) Root() *Condition

Root returns the root Condition, typically "Ready" or "Succeeded"

func (ConditionSet) Set 

func (c ConditionSet) Set(condition Condition) (modified bool)

Set sets or updates the Condition on Conditions for Condition.Type. If there is an update, Conditions are stored back sorted.

func (ConditionSet) SetFalse 

func (c ConditionSet) SetFalse(conditionType string, reason, message string) (modified bool)

SetFalse sets the status of conditionType and the root condition to False.

func (ConditionSet) SetTrue 

func (c ConditionSet) SetTrue(conditionType string) (modified bool)

SetTrue sets the status of conditionType to true with the reason, and then marks the root condition to true if all other dependents are also true.

func (ConditionSet) SetTrueWithReason 

func (c ConditionSet) SetTrueWithReason(conditionType string, reason, message string) (modified bool)

SetTrueWithReason sets the status of conditionType to true with the reason, and then marks the root condition to true if all other dependents are also true.

func (ConditionSet) SetUnknown 

func (c ConditionSet) SetUnknown(conditionType string) (modified bool)

SetUnknown sets the status of conditionType to Unknown and also sets the root condition to Unknown if no other dependent condition is in an error state.

func (ConditionSet) SetUnknownWithReason 

func (c ConditionSet) SetUnknownWithReason(conditionType string, reason, message string) (modified bool)

SetUnknownWithReason sets the status of conditionType to Unknown with the reason, and also sets the root condition to Unknown if no other dependent condition is in an error state.

type ConditionType 

type ConditionType string

ConditionType is a upper-camel-cased condition type.

type ConditionTypes 

type ConditionTypes struct {
	// contains filtered or unexported fields
}

ConditionTypes is an abstract collection of the possible ConditionType values that a particular resource might expose. It also holds the "root condition" for that resource, which we define to be one of Ready or Succeeded depending on whether it is a Living or Batch process respectively.

func NewReadyConditions 

func NewReadyConditions(d ...string) ConditionTypes

NewReadyConditions returns a ConditionTypes to hold the conditions for the resource. ConditionReady is used as the root condition. The set of condition types provided are those of the terminal subconditions.

func NewSucceededConditions 

func NewSucceededConditions(d ...string) ConditionTypes

NewSucceededConditions returns a ConditionTypes to hold the conditions for the batch resource. ConditionSucceeded is used as the root condition. The set of condition types provided are those of the terminal subconditions.
