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 Secrets to the collected outputs
	AddSecrets(secrets ...*v1.Secret)

	// get the collected Secrets
	GetSecrets() v1_sets.SecretSet

	// 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 LabeledSecretSet

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

	// returns the set of Secretes with the given labels
	Set() v1_sets.SecretSet

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

LabeledSecretSet represents a set of secrets which share a common set of labels. These labels are used to find diffs between SecretSets.

func NewLabeledSecretSet

func NewLabeledSecretSet(set v1_sets.SecretSet, labels map[string]string) (LabeledSecretSet, error)

type Snapshot

type Snapshot interface {

	// return the set of Secrets with a given set of labels
	Secrets() []LabeledSecretSet

	// 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,

	secrets v1_sets.SecretSet,
	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,

	secrets v1_sets.SecretSet,
	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,

	secrets []LabeledSecretSet,
	clusters ...string,
) Snapshot
