Functions

func SetCondition 

func SetCondition(o Conditioner, new Condition)

SetCondition sets the provided Condition on the Conditioner. The condition is only set if the new condition is in a different state than the existing condition of the same type.

Types

type Condition 

type Condition struct {
	// Type of condition.
	// +kubebuilder:validation:Required
	Type ConditionType `json:"type"`

	// Status of the condition, one of True, False, or Unknown.
	// +kubebuilder:validation:Required
	Status metav1.ConditionStatus `json:"status"`

	// Severity with which to treat failures of this type of condition.
	// For conditions which have positive polarity (Status == True is their normal/healthy state), this will be omitted when Status == True
	// For conditions which have negative polarity (Status == False is their normal/healthy state), this will be omitted when Status == False.
	// This is omitted in all cases when Status == Unknown
	// +kubebuilder:validation:Optional
	Severity ConditionSeverity `json:"severity,omitempty"`

	// LastTransitionTime is the last time the condition transitioned from one status to another.
	// +kubebuilder:validation:Required
	LastTransitionTime metav1.Time `json:"lastTransitionTime"`

	// ObservedGeneration is the .metadata.generation that the condition was set based upon. For instance, if
	// .metadata.generation is currently 12, but the .status.condition[x].observedGeneration is 9, the condition is out of date
	// with respect to the current state of the instance.
	// +kubebuilder:validation:Optional
	ObservedGeneration int64 `json:"observedGeneration,omitempty"`

	// Reason for the condition's last transition.
	// Reasons are upper CamelCase (PascalCase) with no spaces. A reason is always provided, this field will not be empty.
	// +kubebuilder:validation:Required
	Reason string `json:"reason"`

	// Message is a human readable message indicating details about the transition. This field may be empty.
	// +kubebuilder:validation:Optional
	Message string `json:"message,omitempty"`
}

Condition defines an extension to status (an observation) of a resource +kubebuilder:object:generate=true

func GetCondition 

func GetCondition(o Conditioner, conditionType ConditionType) (Condition, bool)

GetCondition gets the Condition with the specified type from the provided Conditioner. Returns the Condition and true if a Condition with the specified type is found, or an empty Condition and false if not.

func (Condition) Copy 

func (c Condition) Copy() Condition

Copy returns an independent copy of the Condition

func (*Condition) DeepCopy 

func (in *Condition) DeepCopy() *Condition

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) IsEquivalent 

func (c Condition) IsEquivalent(other Condition) bool

IsEquivalent returns true if this condition is equivalent to the passed in condition. Two conditions are equivalent if all of their fields EXCEPT LastTransitionTime are the same.

func (Condition) ShouldOverwrite 

func (c Condition) ShouldOverwrite(other Condition) bool

ShouldOverwrite determines if this condition should overwrite the other condition.

func (Condition) String 

func (c Condition) String() string

String returns a string representation of this condition

type ConditionSeverity 

type ConditionSeverity string

ConditionSeverity expresses the severity of a Condition. 

const (
	// ConditionSeverityError specifies that a failure of a condition type
	// should be viewed as an error. Errors are fatal to reconciliation and
	// mean that the user must take some action to resolve
	// the problem before reconciliation will be attempted again.
	ConditionSeverityError ConditionSeverity = "Error"

	// ConditionSeverityWarning specifies that a failure of a condition type
	// should be viewed as a warning. Warnings are informational. The operator
	// may be able to retry and resolve the warning without any action from the user, but
	// in some cases user action to resolve the warning will be required.
	ConditionSeverityWarning ConditionSeverity = "Warning"

	// ConditionSeverityInfo specifies that a failure of a condition type
	// should be viewed as purely informational. Things are working.
	// This is the happy path.
	ConditionSeverityInfo ConditionSeverity = "Info"

	// ConditionSeverityNone specifies that there is no condition severity.
	// For conditions which have positive polarity (Status == True is their normal/healthy state), this will set when Status == True
	// For conditions which have negative polarity (Status == False is their normal/healthy state), this will be set when Status == False.
	// Conditions in Status == Unknown always have a severity of None as well.
	// This is the default state for conditions.
	ConditionSeverityNone ConditionSeverity = ""
)

type ConditionType 

type ConditionType string

type Conditioner 

type Conditioner interface {
	GetConditions() Conditions
	SetConditions(conditions Conditions)
}

TODO: Hah, name...

type Conditions 

type Conditions []Condition

func (Conditions) FindIndexByType 

func (c Conditions) FindIndexByType(conditionType ConditionType) (int, bool)

FindIndexByType returns the index of the condition with the given ConditionType if it exists. If the Condition with the specified ConditionType is doesn't exist, the second boolean parameter is false.

type PositiveConditionBuilder 

type PositiveConditionBuilder struct {
	Ready *ReadyConditionBuilder
	// contains filtered or unexported fields
}

PositiveConditionBuilder makes positive polarity conditions. A positive polarity condition is a condition where Status==True is the "happy path" state, and Status==False is a failure state.

func NewPositiveConditionBuilder 

func NewPositiveConditionBuilder(clock clock.Clock) *PositiveConditionBuilder

NewPositiveConditionBuilder creates a new PositiveConditionBuilder for creating positive polarity conditions.

func (*PositiveConditionBuilder) MakeFalseCondition 

func (b *PositiveConditionBuilder) MakeFalseCondition(conditionType ConditionType, severity ConditionSeverity, observedGeneration int64, reason string, message string) Condition

MakeFalseCondition makes a condition whose Status is False. A severity, reason, and message must be provided.

func (*PositiveConditionBuilder) MakeTrueCondition 

func (b *PositiveConditionBuilder) MakeTrueCondition(conditionType ConditionType, observedGeneration int64) Condition

MakeTrueCondition makes a condition whose Status is True

func (*PositiveConditionBuilder) MakeUnknownCondition 

func (b *PositiveConditionBuilder) MakeUnknownCondition(conditionType ConditionType, observedGeneration int64, reason string, message string) Condition

MakeUnknownCondition makes a condition whose Status is Unknown. A reason and message must be provided. No severity is required as conditions in Status Unknown do not have a known severity either.

type PositiveConditionBuilderInterface 

type PositiveConditionBuilderInterface interface {
	MakeTrueCondition(conditionType ConditionType, observedGeneration int64) Condition
	MakeFalseCondition(conditionType ConditionType, severity ConditionSeverity, observedGeneration int64, reason string, message string) Condition
	MakeUnknownCondition(conditionType ConditionType, observedGeneration int64, reason string, message string) Condition
}

TODO: name?

ReadyConditionImpactingError is an error that requires notification in the Ready condition

func AsReadyConditionImpactingError 

func AsReadyConditionImpactingError(err error) (*ReadyConditionImpactingError, bool)

func NewReadyConditionImpactingError 

func NewReadyConditionImpactingError(cause error, severity ConditionSeverity, reason string) *ReadyConditionImpactingError
