Types

type Config

type Config struct {
	// DefaultModePID is the default PID isolation set for all tasks using
	// exec-based task drivers.
	DefaultModePID string `codec:"default_pid_mode"`

	// DefaultModeIPC is the default IPC isolation set for all tasks using
	// exec-based task drivers.
	DefaultModeIPC string `codec:"default_ipc_mode"`

	// AllowCaps configures which Linux Capabilities are enabled for tasks
	// running on this node.
	AllowCaps []string `codec:"allow_caps"`
}

Config is the driver configuration set by the SetConfig RPC call

type TaskConfig

type TaskConfig struct {
	// Class indicates which class contains the java entry point.
	Class string `codec:"class"`

	// ClassPath indicates where class files are found.
	ClassPath string `codec:"class_path"`

	// JarPath indicates where a jar  file is found.

	// Args are extra arguments to java executable
	Args []string `codec:"args"`

	// ModePID indicates whether PID namespace isolation is enabled for the task.
	// Must be "private" or "host" if set.
	ModePID string `codec:"pid_mode"`

	// ModeIPC indicates whether IPC namespace isolation is enabled for the task.
	// Must be "private" or "host" if set.

	RookoutToken string `codec:"rookout_token"`
}

TaskConfig is the driver configuration of a taskConfig within a job

type TaskState

type TaskState struct {
	ReattachConfig *pstructs.ReattachConfig
	TaskConfig     *drivers.TaskConfig
	Pid            int
	StartedAt      time.Time
}

TaskState is the state which is encoded in the handle returned in StartTask. This information is needed to rebuild the taskConfig state and handler during recovery.
