Types

type ACIEndpoint

type ACIEndpoint struct {
	ACI string
	Sig string
}

type App

type App struct {
	Name   types.ACName
	Labels map[string]string
}

func NewApp

func NewApp(name string, labels map[string]string) (*App, error)

func NewAppFromString

func NewAppFromString(app string) (*App, error)

NewAppFromString takes a command line app parameter and returns a map of labels.

Example app parameters:

example.com/reduce-worker:1.0.0
example.com/reduce-worker,channel=alpha,label=value

type Endpoints

type Endpoints struct {
	ACIEndpoints []ACIEndpoint
	Keys         []string
}

func DiscoverEndpoints

func DiscoverEndpoints(app App, insecure bool) (eps *Endpoints, err error)

DiscoverEndpoints will make HTTPS requests to find the ac-discovery meta tags and optionally will use HTTP if insecure is set. Based on the app passed the discovery templates will be filled out and returned in eps.
