swarms

type Registry ¶

type Registry interface {
	// Backend returns the backend for the named swarm. The empty name means
	// the swarm this controller runs in.
	//
	// Implementations return the same backend for the same name rather than
	// reconnecting per call: the reconcile loop asks on every tick.
	Backend(ctx context.Context, swarm string) (charts.Backend, error)
}

Registry resolves a swarm name to a backend.

It hands back a charts.Backend rather than an interface of our own. swarmcli-cd is built on the chart engine — charts.NewEngineWith takes any Backend, which is what makes a controller-supplied applier possible at all — and a fourteen-method pass-through would buy nothing but a second definition to keep in step with CE's.
