Functions

func SetGatewayClassAccepted 

func SetGatewayClassAccepted(ctx context.Context, cli client.Client, gc *gatewayapi_v1alpha2.GatewayClass, accepted bool) *gatewayapi_v1alpha2.GatewayClass

SetGatewayClassAccepted inserts or updates the Accepted condition for the provided GatewayClass.

Types

type Cache 

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

Cache holds status updates from the DAG back towards Kubernetes. It holds a per-Kind cache, and is intended to be accessed with a KindAccessor.

func NewCache 

func NewCache(gateway types.NamespacedName, gatewayController gatewayapi_v1alpha2.GatewayController) Cache

NewCache creates a new Cache for holding status updates.

func (*Cache) GatewayStatusAccessor 

func (c *Cache) GatewayStatusAccessor(nsName types.NamespacedName, generation int64, gs *gatewayapi_v1alpha2.GatewayStatus) (*GatewayStatusUpdate, func())

GatewayStatusAccessor returns a GatewayStatusUpdate that allows a client to build up a list of status changes as well as a function to commit the change back to the cache when everything is done. The commit function pattern is used so that the GatewayStatusUpdate does not need to know anything the cache internals.

func (*Cache) Get 

func (c *Cache) Get(obj metav1.Object) CacheEntry

Get returns a pointer to a the cache entry if it exists, nil otherwise. The return value is shared between all callers, who should take care to cooperate.

func (*Cache) GetGatewayUpdates 

func (c *Cache) GetGatewayUpdates() []*GatewayStatusUpdate

GetGatewayUpdates gets the underlying GatewayStatusUpdate objects from the cache.

func (*Cache) GetProxyUpdates 

func (c *Cache) GetProxyUpdates() []*ProxyUpdate

GetProxyUpdates gets the underlying ProxyUpdate objects from the cache, used by various things (`internal/sesame/metrics.go` and `internal/dag/status_test.go`) to retrieve info they need. TODO(youngnick)#2969: This could conceivably be replaced with a Walk pattern.

func (*Cache) GetRouteUpdates 

func (c *Cache) GetRouteUpdates() []*RouteConditionsUpdate

GetRouteUpdates gets the underlying RouteConditionsUpdate objects from the cache.

func (*Cache) GetStatusUpdates 

func (c *Cache) GetStatusUpdates() []k8s.StatusUpdate

GetStatusUpdates returns a slice of StatusUpdates, ready to be sent off to the StatusUpdater by the event handler. As more kinds are handled by Cache, we'll update this method.

func (*Cache) ProxyAccessor 

func (c *Cache) ProxyAccessor(proxy *sesame_api_v1.HTTPProxy) (*ProxyUpdate, func())

ProxyAccessor returns a ProxyUpdate that allows a client to build up a list of errors and warnings to go onto the proxy as conditions, and a function to commit the change back to the cache when everything is done. The commit function pattern is used so that the ProxyUpdate does not need to know anything the cache internals.

func (*Cache) Put 

func (c *Cache) Put(obj metav1.Object, e CacheEntry)

Put returns an entry to the cache.

func (*Cache) RouteConditionsAccessor 

func (c *Cache) RouteConditionsAccessor(nsName types.NamespacedName, generation int64, resource client.Object, gateways []gatewayapi_v1alpha2.RouteParentStatus) (*RouteConditionsUpdate, func())

RouteConditionsAccessor returns a RouteConditionsUpdate that allows a client to build up a list of metav1.Conditions as well as a function to commit the change back to the cache when everything is done. The commit function pattern is used so that the RouteConditionsUpdate does not need to know anything the cache internals.

type CacheEntry 

type CacheEntry interface {
	AsStatusUpdate() k8s.StatusUpdate
	ConditionFor(ConditionType) *sesame_api_v1.DetailedCondition
}

type ConditionCache 

type ConditionCache struct {
	Conditions map[ConditionType]*sesame_api_v1.DetailedCondition
}

ConditionCache holds all the DetailedConditions to add to the object keyed by the Type (since that's what the API server will end up doing).

func (*ConditionCache) ConditionFor 

func (c *ConditionCache) ConditionFor(condType ConditionType) *sesame_api_v1.DetailedCondition

ConditionFor returns the cached DetailedCondition of the given type. If no such condition exists, a new one is created.

type ConditionType 

type ConditionType string

ConditionType is used to ensure we only use a limited set of possible values for DetailedCondition types. It's cast back to a string before sending off to HTTPProxy structs, as those use upstream types which we can't alias easily. 

const ValidCondition ConditionType = "Valid"

ValidCondition is the ConditionType for Valid.

type ExtensionCacheEntry 

type ExtensionCacheEntry struct {
	ConditionCache

	Name           types.NamespacedName
	Generation     int64
	TransitionTime v1.Time
}

ExtensionCacheEntry holds status updates for a particular ExtensionService

func ExtensionAccessor 

func ExtensionAccessor(c *Cache, ext *sesame_api_v1alpha1.ExtensionService) (*ExtensionCacheEntry, func())

ExtensionAccessor returns a pointer to a shared status cache entry for the given ExtensionStatus object. If no such entry exists, a new entry is added. When the caller finishes with the cache entry, it must call the returned function to release the entry back to the cache.

func (*ExtensionCacheEntry) AsStatusUpdate 

func (e *ExtensionCacheEntry) AsStatusUpdate() k8s.StatusUpdate

type GatewayReasonType 

type GatewayReasonType string

type GatewayStatusUpdate 

type GatewayStatusUpdate struct {
	FullName           types.NamespacedName
	Conditions         map[gatewayapi_v1alpha2.GatewayConditionType]metav1.Condition
	ExistingConditions map[gatewayapi_v1alpha2.GatewayConditionType]metav1.Condition
	ListenerStatus     map[string]*gatewayapi_v1alpha2.ListenerStatus
	Generation         int64
	TransitionTime     metav1.Time
}

GatewayStatusUpdate represents an atomic update to a Gateway's status.

func (*GatewayStatusUpdate) AddCondition 

func (gatewayUpdate *GatewayStatusUpdate) AddCondition(
	cond gatewayapi_v1alpha2.GatewayConditionType,
	status metav1.ConditionStatus,
	reason GatewayReasonType,
	message string,
) metav1.Condition

AddCondition returns a metav1.Condition for a given GatewayConditionType.

func (*GatewayStatusUpdate) AddListenerCondition 

func (gatewayUpdate *GatewayStatusUpdate) AddListenerCondition(
	listenerName string,
	cond gatewayapi_v1alpha2.ListenerConditionType,
	status metav1.ConditionStatus,
	reason gatewayapi_v1alpha2.ListenerConditionReason,
	message string,
) metav1.Condition

AddListenerCondition adds a Condition for the specified listener.

func (*GatewayStatusUpdate) Mutate 

func (gatewayUpdate *GatewayStatusUpdate) Mutate(obj client.Object) client.Object

func (*GatewayStatusUpdate) SetListenerAttachedRoutes 

func (gatewayUpdate *GatewayStatusUpdate) SetListenerAttachedRoutes(listenerName string, numRoutes int)

func (*GatewayStatusUpdate) SetListenerSupportedKinds 

func (gatewayUpdate *GatewayStatusUpdate) SetListenerSupportedKinds(listenerName string, kinds []gatewayapi_v1alpha2.Kind)

type ProxyStatus 

type ProxyStatus string
const (
	ProxyStatusValid    ProxyStatus = "valid"
	ProxyStatusInvalid  ProxyStatus = "invalid"
	ProxyStatusOrphaned ProxyStatus = "orphaned"
)

type ProxyUpdate 

type ProxyUpdate struct {
	Fullname       types.NamespacedName
	Generation     int64
	TransitionTime v1.Time
	Vhost          string

	// Conditions holds all the DetailedConditions to add to the object
	// keyed by the Type (since that's what the apiserver will end up
	// doing.)
	Conditions map[ConditionType]*sesame_api_v1.DetailedCondition
}

ProxyUpdate holds status updates for a particular HTTPProxy object

func (*ProxyUpdate) ConditionFor 

func (pu *ProxyUpdate) ConditionFor(cond ConditionType) *sesame_api_v1.DetailedCondition

ConditionFor returns a DetailedCondition for a given ConditionType. Currently only "Valid" is used.

func (*ProxyUpdate) Mutate 

func (pu *ProxyUpdate) Mutate(obj client.Object) client.Object

type RouteConditionsUpdate 

type RouteConditionsUpdate struct {
	FullName           types.NamespacedName

	ExistingConditions map[gatewayapi_v1alpha2.RouteConditionType]metav1.Condition
	GatewayRef         types.NamespacedName
	GatewayController  gatewayapi_v1alpha2.GatewayController
