Functions ¶

func DeletePid ¶

func DeletePid(path string) error

DeletePid removes the pid and started file from disk when the container's process dies and the container is cleanly removed

func Exec ¶

func Exec(container *libcontainer.Container, term Terminal, rootfs, dataPath string, args []string, createCommand CreateCommand, startCallback func()) (int, error)

func GetNamespaceFlags ¶

func GetNamespaceFlags(namespaces map[string]bool) (flag int)

func Init ¶

func Init(container *libcontainer.Container, uncleanRootfs, consolePath string, syncPipe *SyncPipe, args []string) error

func InitializeNetworking ¶

func InitializeNetworking(container *libcontainer.Container, nspid int, pipe *SyncPipe) error

func SetupCgroups ¶

func SetupCgroups(container *libcontainer.Container, nspid int) (cgroups.ActiveCgroup, error)

func WritePid ¶

func WritePid(path string, pid int, startTime string) error

WritePid writes the namespaced processes pid to pid and it's start time to the path specified

Types ¶

type CreateCommand ¶

type CreateCommand func(container *libcontainer.Container, console, rootfs, dataPath, init string, childPipe *os.File, args []string) *exec.Cmd

type StdTerminal ¶

type StdTerminal struct {
	// contains filtered or unexported fields
}

func (*StdTerminal) Attach ¶

func (s *StdTerminal) Attach(command *exec.Cmd) error

func (*StdTerminal) Close ¶
