Functions

func NewExecDriver

func NewExecDriver(ctx context.Context, logger hclog.Logger) drivers.DriverPlugin

NewExecDriver returns a new DrivePlugin implementation

Types

type Config

type Config struct {
	// NoPivotRoot disables the use of pivot_root, useful when the root partition
	// is on ramdisk
	NoPivotRoot bool `codec:"no_pivot_root"`
}

Config is the driver configuration set by the SetConfig RPC call

type Driver

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

Driver fork/execs tasks using many of the underlying OS's isolation features where configured.

func (*Driver) Capabilities

func (d *Driver) Capabilities() (*drivers.Capabilities, error)

func (*Driver) ConfigSchema

func (d *Driver) ConfigSchema() (*hclspec.Spec, error)

func (*Driver) DestroyTask

func (d *Driver) DestroyTask(taskID string, force bool) error

func (*Driver) ExecTask

func (d *Driver) ExecTask(taskID string, cmd []string, timeout time.Duration) (*drivers.ExecTaskResult, error)

func (*Driver) ExecTaskStreamingRaw

func (d *Driver) ExecTaskStreamingRaw(ctx context.Context,
	taskID string,
	command []string,
	tty bool,
	stream drivers.ExecTaskStream) error

func (*Driver) Fingerprint

func (d *Driver) Fingerprint(ctx context.Context) (<-chan *drivers.Fingerprint, error)

func (*Driver) InspectTask

func (d *Driver) InspectTask(taskID string) (*drivers.TaskStatus, error)

func (*Driver) PluginInfo

func (d *Driver) PluginInfo() (*base.PluginInfoResponse, error)

func (*Driver) RecoverTask

func (d *Driver) RecoverTask(handle *drivers.TaskHandle) error

func (*Driver) SetConfig

func (d *Driver) SetConfig(cfg *base.Config) error

func (*Driver) SignalTask

func (d *Driver) SignalTask(taskID string, signal string) error

func (*Driver) StartTask

func (d *Driver) StartTask(cfg *drivers.TaskConfig) (*drivers.TaskHandle, *drivers.DriverNetwork, error)

func (*Driver) StopTask

func (d *Driver) StopTask(taskID string, timeout time.Duration, signal string) error

func (*Driver) TaskConfigSchema

func (d *Driver) TaskConfigSchema() (*hclspec.Spec, error)

func (*Driver) TaskEvents

func (d *Driver) TaskEvents(ctx context.Context) (<-chan *drivers.TaskEvent, error)

func (*Driver) TaskStats

func (d *Driver) TaskStats(ctx context.Context, taskID string, interval time.Duration) (<-chan *drivers.TaskResourceUsage, error)

func (*Driver) WaitTask

func (d *Driver) WaitTask(ctx context.Context, taskID string) (<-chan *drivers.ExitResult, error)

type TaskConfig

type TaskConfig struct {
	Command string   `codec:"command"`
	Args    []string `codec:"args"`
}

TaskConfig is the driver configuration of a task 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 task state and handler during recovery.
