Environment configuration

All RoadRunner workers will inherit the system configuration available for the parent server process. In addition, you can customize the set of env variables to be passed to your workers using part env of .rr configuration file.

env:
   key: value

All keys will be automatically uppercased!

Additional Customizations

Internally, RoadRunner services receive configuration using env.Environment interface dependency. This allows you to create your own method to deliver env variables to workers:

type Environment interface {
	GetEnv() (map[string]string, error)
	SetEnv(key, value string)
}

func main() {
	rr.Logger.Formatter = &logrus.TextFormatter{ForceColors: true}

        // get env vars via consul
	rr.Container.Register(sd.ID, consul.NewService())

	rr.Container.Register(rpc.ID, &rpc.Service{})
	rr.Container.Register(http.ID, &http.Service{})
	rr.Container.Register(static.ID, &static.Service{})

	// you can register additional commands using cmd.CLI
	rr.Execute()
}

You must remove default env component.
