Types

type CompactGVKEquivalenceSet

type CompactGVKEquivalenceSet struct {
	Groups   []string `json:"groups"`
	Versions []string `json:"versions"`
	Kinds    []string `json:"kinds"`
}

compactGVKEquivalenceSet contains a set of equivalent GVKs, expressed in the compact form [groups, versions, kinds] where any combination of items from these three fields can be considered a valid equivalent. Used for unmarshalling as this is the form used in requiressync annotations.

type CompactSyncRequirements

type CompactSyncRequirements [][]CompactGVKEquivalenceSet

CompactSyncRequirements contains a list of ANDed requirements, each of which contains a list of equivalent (ORed) GVKs in compact form.

type GVKEquivalenceSet

type GVKEquivalenceSet map[schema.GroupVersionKind]struct{}

GVKEquivalenceSet is a set of GVKs that a template can use interchangeably in its referential policy implementation.

func ExpandCompactEquivalenceSet

func ExpandCompactEquivalenceSet(compactEquivalenceSet CompactGVKEquivalenceSet) GVKEquivalenceSet

Takes a compactGVKSet and expands it into a GVKEquivalenceSet.

type SyncRequirements

type SyncRequirements []GVKEquivalenceSet

SyncRequirements contains a list of ANDed requirements, each of which contains an expanded set of equivalent (ORed) GVKs.

func ExpandCompactRequirements

func ExpandCompactRequirements(compactSyncRequirements CompactSyncRequirements) (SyncRequirements, error)

Takes a CompactSyncRequirements (the json form provided in the template annotation) and expands it into a SyncRequirements.

func ReadSyncRequirements

func ReadSyncRequirements(t *templates.ConstraintTemplate) (SyncRequirements, error)

ReadSyncRequirements parses the sync requirements from a constraint template.
