var Indexing = NewRegister()

Indexing is the singleton Register instance where all Indexers and Matchers are stored

Functions

func IndexerPlugin

func IndexerPlugin(name string, c IndexerConstructor) map[string][]interface{}

func MatcherPlugin

func MatcherPlugin(name string, m MatcherConstructor) map[string][]interface{}

Types

type ContainerIndexer

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

ContainerIndexer indexes pods based on all their containers IDs

func (*ContainerIndexer) GetIndexes

func (c *ContainerIndexer) GetIndexes(pod *kubernetes.Pod) []string

GetIndexes returns the indexes for the given Pod

func (*ContainerIndexer) GetMetadata

func (c *ContainerIndexer) GetMetadata(pod *kubernetes.Pod) []MetadataIndex

GetMetadata returns the composed metadata list from all registered indexers

type Enabled

type Enabled struct {
	Enabled bool `config:"enabled"`
}

type FieldFormatMatcher

type FieldFormatMatcher struct {
	Codec codec.Codec
}

func (*FieldFormatMatcher) MetadataIndex

func (f *FieldFormatMatcher) MetadataIndex(event common.MapStr) string

type FieldMatcher

type FieldMatcher struct {
	MatchFields []string
}

func (*FieldMatcher) MetadataIndex

func (f *FieldMatcher) MetadataIndex(event common.MapStr) string

type IPPortIndexer

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

IPPortIndexer indexes pods based on all their host:port combinations

func (*IPPortIndexer) GetIndexes

func (h *IPPortIndexer) GetIndexes(pod *kubernetes.Pod) []string

GetIndexes returns the indexes for the given Pod

func (*IPPortIndexer) GetMetadata

func (h *IPPortIndexer) GetMetadata(pod *kubernetes.Pod) []MetadataIndex

GetMetadata returns metadata for the given pod, if it matches the index

type Indexer

type Indexer interface {
	// GetMetadata generates event metadata for the given pod, then returns the
	// list of indexes to create, with the metadata to put on them
	GetMetadata(pod *kubernetes.Pod) []MetadataIndex

	// GetIndexes return the list of indexes the given pod belongs to. This function
	// must return the same indexes than GetMetadata
	GetIndexes(pod *kubernetes.Pod) []string
}

Indexer take known pods and generate all the metadata we need to enrich events in a efficient way. By preindexing the metadata in the way it will be checked when matching events

func NewContainerIndexer

func NewContainerIndexer(_ common.Config, metaGen kubernetes.MetaGenerator) (Indexer, error)

NewContainerIndexer initializes and returns a ContainerIndexer

func NewIPPortIndexer

func NewIPPortIndexer(_ common.Config, metaGen kubernetes.MetaGenerator) (Indexer, error)

NewIPPortIndexer creates and returns a new indexer for pod IP & ports

func NewPodNameIndexer

func NewPodNameIndexer(_ common.Config, metaGen kubernetes.MetaGenerator) (Indexer, error)

NewPodNameIndexer initializes and returns a PodNameIndexer

type IndexerConstructor

type IndexerConstructor func(config common.Config, metaGen kubernetes.MetaGenerator) (Indexer, error)

IndexerConstructor builds a new indexer from its settings

type Indexers

type Indexers struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

func NewIndexers

func NewIndexers(configs PluginConfig, metaGen kubernetes.MetaGenerator) *Indexers

NewIndexers builds indexers object

func (*Indexers) Empty

func (i *Indexers) Empty() bool

Empty returns true if indexers list is empty

func (*Indexers) GetIndexes

func (i *Indexers) GetIndexes(pod *kubernetes.Pod) []string

GetIndexes returns the composed index list from all registered indexers

func (*Indexers) GetMetadata

func (i *Indexers) GetMetadata(pod *kubernetes.Pod) []MetadataIndex

GetMetadata returns the composed metadata list from all registered indexers

type Matcher

type Matcher interface {
	// MetadataIndex returns the index string to use in annotation lookups for the given
	// event. A previous indexer should have generated that index for this to work
	// This function can return "" if the event doesn't match
	MetadataIndex(event common.MapStr) string
}

Matcher takes a new event and returns the index

func NewFieldFormatMatcher

func NewFieldFormatMatcher(cfg common.Config) (Matcher, error)

func NewFieldMatcher

func NewFieldMatcher(cfg common.Config) (Matcher, error)

type MatcherConstructor

type MatcherConstructor func(config common.Config) (Matcher, error)

type Matchers

type Matchers struct {

func NewMatchers(configs PluginConfig) *Matchers

func (*Matchers) Empty

func (m *Matchers) Empty() bool

func (*Matchers) MetadataIndex

func (m *Matchers) MetadataIndex(event common.MapStr) string

MetadataIndex returns the index string for the first matcher from the Registry returning one

type MetadataIndex

GetIndexes returns the indexes for the given Pod

func (*PodNameIndexer) GetMetadata

func (p *PodNameIndexer) GetMetadata(pod *kubernetes.Pod) []MetadataIndex

GetMetadata returns metadata for the given pod, if it matches the index

type Register

type Register struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

Register contains Indexer and Matchers to use on pod indexing and event matching
