Types ¶

type Cache ¶

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

Cache keeps track of resource instances provided to it via Update method and implements the Instancer interface

func NewCache ¶

func NewCache() *Cache

NewCache creates a new Cache.

func (*Cache) Deregister ¶

func (c *Cache) Deregister(ch chan<- sd.Event)

Deregister implements Instancer.

func (*Cache) Register ¶

func (c *Cache) Register(ch chan<- sd.Event)

Register implements Instancer.

func (*Cache) State ¶

func (c *Cache) State() sd.Event

State returns the current state of discovery (instances or error) as sd.Event

func (*Cache) Stop ¶

func (c *Cache) Stop()

Stop implements Instancer. Since the cache is just a plain-old store of data, Stop is a no-op.

func (*Cache) Update ¶

func (c *Cache) Update(event sd.Event)

Update receives new instances from service discovery, stores them internally, and notifies all registered listeners.

type Instancer ¶

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

Instancer yields instances for a service in Consul.

func NewInstancer ¶

func NewInstancer(client csd.Client, logger log.Logger, service string, tags []string, passingOnly bool, listener Listener) *Instancer

NewInstancer returns a Consul instancer that publishes instances for the requested service. It only returns instances for which all of the passed tags are present.

func (*Instancer) Deregister ¶

func (s *Instancer) Deregister(ch chan<- sd.Event)

Deregister implements Instancer.

func (*Instancer) GetTagMap ¶

func (s *Instancer) GetTagMap() map[string][]string

GetTagMap returns tags as map

func (*Instancer) Register ¶

func (s *Instancer) Register(ch chan<- sd.Event)

Register implements Instancer.

func (*Instancer) SetListener ¶

func (s *Instancer) SetListener(l Listener)

SetListener set the update listener

func (*Instancer) Stop ¶
