Overview

Package daemon runs Ripen on a schedule. It owns its process and writes nothing to stdout: the Event stream on stderr is its entire output, which is what lets a container's logs be parsed as a stream of Events and nothing else.

Functions

func Run 

func Run(ctx context.Context, options Options) error

Run drives the loop until the context ends, or once when Once is set. A failed cycle is not a failed daemon: the engine has already put a run.failed Event on the stream, and the next cycle tries again.

Types

type Engine 

type Engine interface {
	Schedule(context.Context, domain.Mode, time.Duration) error
	RunContext(context.Context, domain.Mode) (updater.Report, error)
}

Engine coordinates scheduled and finite runs.

type Options 

type Options struct {
	Updater  Engine
	Mode     domain.Mode
	Interval time.Duration
	// Once runs a single cycle and returns its error. Nothing sleeps.
	Once bool
}

Options configures a daemon loop.
