Types

type Driver added in v1.9.0

type Driver struct {
	sync.Mutex
	// contains filtered or unexported fields
}

Driver contains all information for lxc driver, it implements execdriver.Driver

func NewDriver

func NewDriver(root, libPath, initPath string, apparmor bool) (*Driver, error)

NewDriver returns a new lxc driver, called from NewDriver of execdriver

func (*Driver) Clean added in v1.9.0

func (d *Driver) Clean(id string) error

Clean implements the exec driver Driver interface, it's not implemented by lxc.

func (*Driver) Exec added in v1.9.0

func (d *Driver) Exec(c *execdriver.Command, processConfig *execdriver.ProcessConfig, pipes *execdriver.Pipes, hooks execdriver.Hooks) (int, error)

Exec implements the exec driver Driver interface, it is not implemented by lxc.

func (*Driver) GetPidsForContainer added in v1.9.0

func (d *Driver) GetPidsForContainer(id string) ([]int, error)

GetPidsForContainer implements the exec driver Driver interface.

func (*Driver) Info added in v1.9.0

func (d *Driver) Info(id string) execdriver.Info

Info implements the exec driver Driver interface.

func (*Driver) Kill added in v1.9.0

func (d *Driver) Kill(c *execdriver.Command, sig int) error

Kill implements the exec driver Driver interface.

func (*Driver) Name added in v1.9.0

func (d *Driver) Name() string

Name implements the exec driver Driver interface.

func (*Driver) Pause added in v1.9.0

func (d *Driver) Pause(c *execdriver.Command) error

Pause implements the exec driver Driver interface, it executes lxc-freeze to pause a container.

func (*Driver) Run added in v1.9.0

Run implements the exec driver Driver interface, it calls 'exec.Cmd' to launch lxc commands to run a container.

func (*Driver) Stats added in v1.9.0

func (d *Driver) Stats(id string) (*execdriver.ResourceStats, error)

Stats implements the exec driver Driver interface. Lxc doesn't implement it's own Stats, it does some trick by implementing execdriver.Stats to get stats info by libcontainer APIs.

func (*Driver) SupportsHooks added in v1.9.0

func (d *Driver) SupportsHooks() bool

SupportsHooks implements the execdriver Driver interface. The LXC execdriver does not support the hook mechanism, which is currently unique to runC/libcontainer.

func (d *Driver) Terminate(c *execdriver.Command) error

Terminate implements the exec driver Driver interface.

func (*Driver) Unpause added in v1.9.0

	Pipe       int
	Root       string
	CapAdd     string
	CapDrop    string
}
