this error can occur if constructing a Partitioned Snapshot from a resource that is missing the partition label

Types

type Builder

type Builder interface {

	// add TrafficSplits to the collected outputs
	AddTrafficSplits(trafficSplits ...*split_smi_spec_io_v1alpha2.TrafficSplit)

	// get the collected TrafficSplits
	GetTrafficSplits() split_smi_spec_io_v1alpha2_sets.TrafficSplitSet

	// add TrafficTargets to the collected outputs
	AddTrafficTargets(trafficTargets ...*access_smi_spec_io_v1alpha2.TrafficTarget)

	// get the collected TrafficTargets
	GetTrafficTargets() access_smi_spec_io_v1alpha2_sets.TrafficTargetSet

	// add HTTPRouteGroups to the collected outputs
	AddHTTPRouteGroups(hTTPRouteGroups ...*specs_smi_spec_io_v1alpha3.HTTPRouteGroup)

	// get the collected HTTPRouteGroups
	GetHTTPRouteGroups() specs_smi_spec_io_v1alpha3_sets.HTTPRouteGroupSet

	// build the collected outputs into a label-partitioned snapshot
	BuildLabelPartitionedSnapshot(labelKey string) (Snapshot, error)

	// build the collected outputs into a snapshot with a single partition
	BuildSinglePartitionedSnapshot(snapshotLabels map[string]string) (Snapshot, error)

	// add a cluster to the collected clusters.
	// this can be used to collect clusters for use with MultiCluster snapshots.
	AddCluster(cluster string)

	// returns the set of clusters currently stored in this builder
	Clusters() []string

	// merge all the resources from another Builder into this one
	Merge(other Builder)

	// create a clone of this builder (deepcopying all resources)
	Clone() Builder
}

the output Builder uses a builder pattern to allow iteratively collecting outputs before producing a final snapshot

type LabeledHTTPRouteGroupSet

type LabeledHTTPRouteGroupSet interface {
	// returns the set of Labels shared by this HTTPRouteGroupSet
	Labels() map[string]string

	// returns the set of HTTPRouteGroupes with the given labels
	Set() specs_smi_spec_io_v1alpha3_sets.HTTPRouteGroupSet

	// converts the set to a generic format which can be applied by the Snapshot.Apply functions
	Generic() output.ResourceList
}

LabeledHTTPRouteGroupSet represents a set of hTTPRouteGroups which share a common set of labels. These labels are used to find diffs between HTTPRouteGroupSets.

type LabeledTrafficSplitSet

type LabeledTrafficSplitSet interface {
	// returns the set of Labels shared by this TrafficSplitSet
	Labels() map[string]string

	// returns the set of TrafficSplites with the given labels
	Set() split_smi_spec_io_v1alpha2_sets.TrafficSplitSet

	// converts the set to a generic format which can be applied by the Snapshot.Apply functions
	Generic() output.ResourceList
}

LabeledTrafficSplitSet represents a set of trafficSplits which share a common set of labels. These labels are used to find diffs between TrafficSplitSets.

type LabeledTrafficTargetSet

type LabeledTrafficTargetSet interface {
	// returns the set of Labels shared by this TrafficTargetSet
	Labels() map[string]string

	// returns the set of TrafficTargetes with the given labels
	Set() access_smi_spec_io_v1alpha2_sets.TrafficTargetSet

	// converts the set to a generic format which can be applied by the Snapshot.Apply functions
	Generic() output.ResourceList
}

LabeledTrafficTargetSet represents a set of trafficTargets which share a common set of labels. These labels are used to find diffs between TrafficTargetSets.

type Snapshot

type Snapshot interface {

	// return the set of TrafficSplits with a given set of labels
	TrafficSplits() []LabeledTrafficSplitSet
	// return the set of TrafficTargets with a given set of labels
	TrafficTargets() []LabeledTrafficTargetSet
	// return the set of HTTPRouteGroups with a given set of labels
	HTTPRouteGroups() []LabeledHTTPRouteGroupSet

	// apply the snapshot to the local cluster, garbage collecting stale resources
	ApplyLocalCluster(ctx context.Context, clusterClient client.Client, errHandler output.ErrorHandler)

	// apply resources from the snapshot across multiple clusters, garbage collecting stale resources
	ApplyMultiCluster(ctx context.Context, multiClusterClient multicluster.Client, errHandler output.ErrorHandler)

	// serialize the entire snapshot as JSON
	MarshalJSON() ([]byte, error)
}

the snapshot of output resources produced by a translation

func NewLabelPartitionedSnapshot

func NewLabelPartitionedSnapshot(
	name,
	labelKey string,

	trafficSplits split_smi_spec_io_v1alpha2_sets.TrafficSplitSet,

	trafficTargets access_smi_spec_io_v1alpha2_sets.TrafficTargetSet,

	hTTPRouteGroups specs_smi_spec_io_v1alpha3_sets.HTTPRouteGroupSet,
	clusters ...string,
) (Snapshot, error)

automatically partitions the input resources by the presence of the provided label.

func NewSinglePartitionedSnapshot

func NewSinglePartitionedSnapshot(
	name string,
	snapshotLabels map[string]string,

	trafficSplits split_smi_spec_io_v1alpha2_sets.TrafficSplitSet,

	trafficTargets access_smi_spec_io_v1alpha2_sets.TrafficTargetSet,

	hTTPRouteGroups specs_smi_spec_io_v1alpha3_sets.HTTPRouteGroupSet,
	clusters ...string,
) (Snapshot, error)

simplified constructor for a snapshot with a single label partition (i.e. all resources share a single set of labels).

func NewSnapshot

func NewSnapshot(
	name string,

	trafficSplits []LabeledTrafficSplitSet,
	trafficTargets []LabeledTrafficTargetSet,
	hTTPRouteGroups []LabeledHTTPRouteGroupSet,
	clusters ...string,
) Snapshot
