var MissingRequiredLabelError = func(labelKey, resourceKind string, obj ezkube.ResourceId) error {
	return eris.Errorf("expected label %v not on labels of %v %v", labelKey, resourceKind, sets.Key(obj))
}

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 VirtualServices to the collected outputs
	AddVirtualServices(virtualServices ...*appmesh_k8s_aws_v1beta2.VirtualService)

	// get the collected VirtualServices
	GetVirtualServices() appmesh_k8s_aws_v1beta2_sets.VirtualServiceSet

	// add VirtualNodes to the collected outputs
	AddVirtualNodes(virtualNodes ...*appmesh_k8s_aws_v1beta2.VirtualNode)

	// get the collected VirtualNodes
	GetVirtualNodes() appmesh_k8s_aws_v1beta2_sets.VirtualNodeSet

	// add VirtualRouters to the collected outputs
	AddVirtualRouters(virtualRouters ...*appmesh_k8s_aws_v1beta2.VirtualRouter)

	// get the collected VirtualRouters
	GetVirtualRouters() appmesh_k8s_aws_v1beta2_sets.VirtualRouterSet

	// 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

	// return the difference between the snapshot in this builder's and another
	Delta(newSnap Builder) output.SnapshotDelta

	// convert this snapshot to its generic form
	Generic() resource.ClusterSnapshot
}

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

type LabeledVirtualNodeSet

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

	// returns the set of VirtualNodees with the given labels
	Set() appmesh_k8s_aws_v1beta2_sets.VirtualNodeSet

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

LabeledVirtualNodeSet represents a set of virtualNodes which share a common set of labels. These labels are used to find diffs between VirtualNodeSets.

func NewLabeledVirtualNodeSet

func NewLabeledVirtualNodeSet(set appmesh_k8s_aws_v1beta2_sets.VirtualNodeSet, labels map[string]string) (LabeledVirtualNodeSet, error)

type LabeledVirtualRouterSet

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

	// returns the set of VirtualRouteres with the given labels
	Set() appmesh_k8s_aws_v1beta2_sets.VirtualRouterSet

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

LabeledVirtualRouterSet represents a set of virtualRouters which share a common set of labels. These labels are used to find diffs between VirtualRouterSets.

func NewLabeledVirtualRouterSet

func NewLabeledVirtualRouterSet(set appmesh_k8s_aws_v1beta2_sets.VirtualRouterSet, labels map[string]string) (LabeledVirtualRouterSet, error)

type LabeledVirtualServiceSet

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

	// returns the set of VirtualServicees with the given labels
	Set() appmesh_k8s_aws_v1beta2_sets.VirtualServiceSet

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

LabeledVirtualServiceSet represents a set of virtualServices which share a common set of labels. These labels are used to find diffs between VirtualServiceSets.

func NewLabeledVirtualServiceSet

func NewLabeledVirtualServiceSet(set appmesh_k8s_aws_v1beta2_sets.VirtualServiceSet, labels map[string]string) (LabeledVirtualServiceSet, error)

type Snapshot

type Snapshot interface {

	// return the set of VirtualServices with a given set of labels
	VirtualServices() []LabeledVirtualServiceSet
	// return the set of VirtualNodes with a given set of labels
	VirtualNodes() []LabeledVirtualNodeSet
	// return the set of VirtualRouters with a given set of labels
	VirtualRouters() []LabeledVirtualRouterSet

	// 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,

	virtualServices appmesh_k8s_aws_v1beta2_sets.VirtualServiceSet,
	virtualNodes appmesh_k8s_aws_v1beta2_sets.VirtualNodeSet,
	virtualRouters appmesh_k8s_aws_v1beta2_sets.VirtualRouterSet,
	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,

	virtualServices appmesh_k8s_aws_v1beta2_sets.VirtualServiceSet,
	virtualNodes appmesh_k8s_aws_v1beta2_sets.VirtualNodeSet,
	virtualRouters appmesh_k8s_aws_v1beta2_sets.VirtualRouterSet,
	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,

	virtualServices []LabeledVirtualServiceSet,
	virtualNodes []LabeledVirtualNodeSet,
	virtualRouters []LabeledVirtualRouterSet,
	clusters ...string,
) Snapshot
