Types ¶

type Client ¶

type Client interface {
	// Register a service with the local agent.
	Register(r *consul.AgentServiceRegistration) error

	// Deregister a service with the local agent.
	Deregister(r *consul.AgentServiceRegistration) error

	// Service
	Service(service, tag string, passingOnly bool, queryOpts *consul.QueryOptions) ([]*consul.ServiceEntry, *consul.QueryMeta, error)
}

Client is a wrapper around the Consul API.

func NewClient ¶

func NewClient(c *consul.Client) Client

NewClient returns an implementation of the Client interface, wrapping a concrete Consul client.

type Instancer ¶

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

Instancer yields instances for a service in Consul.

func NewInstancer ¶

func NewInstancer(client Client, logger log.Logger, service string, tags []string, passingOnly bool) *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) Register ¶

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

Register implements Instancer.

func (*Instancer) Stop ¶

func (s *Instancer) Stop()

Stop terminates the instancer.

type Registrar ¶

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

Registrar registers service instance liveness information to Consul.

func NewRegistrar ¶

func NewRegistrar(client Client, r *stdconsul.AgentServiceRegistration, logger log.Logger) *Registrar

NewRegistrar returns a Consul Registrar acting on the provided catalog registration.

func (*Registrar) Deregister ¶

func (p *Registrar) Deregister()

Deregister implements sd.Registrar interface.

func (*Registrar) Register ¶

func (p *Registrar) Register()

Register implements sd.Registrar interface.
