Types ¶

type API ¶

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

API allows controller machines to claim responsibility for; or to wait for no other machine to have responsibility for; administration for some model.

func NewAPI ¶

func NewAPI(apiCaller base.APICaller, controllerTag names.MachineTag) (*API, error)

NewAPI returns a new API client for the Singular facade. It exposes methods for claiming and observing administration responsibility for the apiCaller's model, on behalf of the supplied controller machine.

func (*API) Claim ¶

func (api *API) Claim(duration time.Duration) error

Claim attempts to claim responsibility for model administration for the supplied duration. If the claim is denied, it will return lease.ErrClaimDenied.

func (*API) Wait ¶

func (api *API) Wait() error

Wait blocks until nobody has responsibility for model administration. It should probably be doing something watchy rather than blocky, but it's following the lease manager implementation underlying the original leadership approach and it doesn't seem worth rewriting all that.
