Constants

const (
	// PelotonJobIDLabelKey is the task label key for job ID
	PelotonJobIDLabelKey = "peloton.job_id"
	// PelotonInstanceIDLabelKey is the task label key for task instance ID
	PelotonInstanceIDLabelKey = "peloton.instance_id"

Variables

var (

	// ErrPortMismatch represents port not matching.
	ErrPortMismatch = errors.New("port in launch not in offer")
	// ErrNotEnoughResource means resource is not enough to match given task.
	ErrNotEnoughResource = errors.New("not enough resources left to run task")

Types

type Builder

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

Builder helps to build launchable Mesos TaskInfo from offers and peloton task configs.

func NewBuilder

func NewBuilder(
	resources []*mesos.Resource) *Builder

NewBuilder creates a new instance of Builder, which caller can use to build Mesos tasks from the cached resources.

func (*Builder) Build

func (tb *Builder) Build(
	task *hostsvc.LaunchableTask,
) (*mesos.TaskInfo, error)

Build is used to build a `mesos.TaskInfo` from cached resources. Caller can keep calling this function to build more tasks. This returns error if the current instance does not have enough resources leftover (scalar, port in future), or the taskConfig is not correct.
