Functions

func DumpConfigFile 

func DumpConfigFile(c interface{}, path string) error

For nydusd as FUSE daemon. Serialize Daemon info and persist to a json file We don't have to persist configuration file for fscache since its configuration is passed through HTTP API.

func DumpConfigString 

func DumpConfigString(c interface{}) (string, error)

func SupplementDaemonConfig 

func SupplementDaemonConfig(c DaemonConfig, imageID, snapshotID string,
	vpcRegistry bool, labels map[string]string, params map[string]string) error

Achieve a daemon configuration from template or snapshotter's configuration
