func NewDaemon(opt ...NewDaemonOpt) (*Daemon, error)

func (*Daemon) BootstrapFile

func (d *Daemon) BootstrapFile() (string, error)

func (*Daemon) CheckStatus

func (d *Daemon) CheckStatus() (*model.DaemonInfo, error)

func (*Daemon) ConfigFile

func (d *Daemon) ConfigFile() string

func (*Daemon) FscacheWorkDir

func (d *Daemon) FscacheWorkDir() string

func (*Daemon) GetAPISock

func (d *Daemon) GetAPISock() string

func (*Daemon) GetFsMetric

func (d *Daemon) GetFsMetric(sharedDaemon bool, sid string) (*model.FsMetric, error)

func (*Daemon) IsMultipleDaemon

func (d *Daemon) IsMultipleDaemon() bool

func (*Daemon) IsPrefetchDaemon

func (d *Daemon) IsPrefetchDaemon() bool

func (*Daemon) IsSharedDaemon

func (d *Daemon) IsSharedDaemon() bool

func (*Daemon) LogFile

func (d *Daemon) LogFile() string

func (*Daemon) MountPoint

func (d *Daemon) MountPoint() string

Mountpoint of per-image nydusd/rafs. It is a kernel mountpoint for each nydus meta layer. Each meta layer is associated with a nydusd.

func (*Daemon) NydusdThreadNum

func (d *Daemon) NydusdThreadNum() string

NydusdThreadNum returns `nydusd-thread-num` for nydusd if set, otherwise will return the number of CPUs as default.

func (*Daemon) OldMountPoint

func (d *Daemon) OldMountPoint() string

Keep this for backwards compatibility

func (*Daemon) SharedAbsMountPoint

func (d *Daemon) SharedAbsMountPoint() string

This is generally used for overlayfs lower dir path.

func (*Daemon) SharedMount

func (d *Daemon) SharedMount() error

func (*Daemon) SharedMountPoint

func (d *Daemon) SharedMountPoint() string

Mountpoint for nydusd within single kernel mountpoint(FUSE mount). Each mountpoint is create by API based pseudo mount. `RootMountPoint` is real mountpoint where to perform the kernel mount. Nydusd API based mountpoint must start with "/", otherwise nydusd API server returns error.

func (*Daemon) SharedUmount

func (d *Daemon) SharedUmount() error

func (*Daemon) WaitUntilReady

func (d *Daemon) WaitUntilReady() error
