示例1: machine

func (i *importer) machine(m description.Machine) error {
	// Import this machine, then import its containers.
	i.logger.Debugf("importing machine %s", m.Id())

	// 1. construct a machineDoc
	mdoc, err := i.makeMachineDoc(m)
	if err != nil {
		return errors.Annotatef(err, "machine %s", m.Id())
	}
	// 2. construct enough MachineTemplate to pass into 'insertNewMachineOps'
	//    - adds constraints doc
	//    - adds status doc
	//    - adds requested network doc
	//    - adds machine block devices doc

	// TODO: consider filesystems and volumes
	mStatus := m.Status()
	if mStatus == nil {
		return errors.NotValidf("missing status")
	}
	machineStatusDoc := statusDoc{
		ModelUUID:  i.st.ModelUUID(),
		Status:     status.Status(mStatus.Value()),
		StatusInfo: mStatus.Message(),
		StatusData: mStatus.Data(),
		Updated:    mStatus.Updated().UnixNano(),
	}
	// XXX(mjs) - this needs to be included in the serialized model
	// (a card exists for the work). Fake it for now.
	instanceStatusDoc := statusDoc{
		ModelUUID: i.st.ModelUUID(),
		Status:    status.StatusStarted,
	}
	cons := i.constraints(m.Constraints())
	networks := []string{}
	prereqOps, machineOp := i.st.baseNewMachineOps(mdoc, machineStatusDoc,
		instanceStatusDoc, cons, networks)

	// 3. create op for adding in instance data
	if instance := m.Instance(); instance != nil {
		prereqOps = append(prereqOps, i.machineInstanceOp(mdoc, instance))
	}

	if parentId := ParentId(mdoc.Id); parentId != "" {
		prereqOps = append(prereqOps,
			// Update containers record for host machine.
			i.st.addChildToContainerRefOp(parentId, mdoc.Id),
		)
	}
	// insertNewContainerRefOp adds an empty doc into the containerRefsC
	// collection for the machine being added.
	prereqOps = append(prereqOps, i.st.insertNewContainerRefOp(mdoc.Id))

	// 4. gather prereqs and machine op, run ops.
	ops := append(prereqOps, machineOp)

	// 5. add any ops that we may need to add the opened ports information.
	ops = append(ops, i.machinePortsOps(m)...)

	if err := i.st.runTransaction(ops); err != nil {
		return errors.Trace(err)
	}

	machine := newMachine(i.st, mdoc)
	if annotations := m.Annotations(); len(annotations) > 0 {
		if err := i.st.SetAnnotations(machine, annotations); err != nil {
			return errors.Trace(err)
		}
	}
	if err := i.importStatusHistory(machine.globalKey(), m.StatusHistory()); err != nil {
		return errors.Trace(err)
	}

	// Now that this machine exists in the database, process each of the
	// containers in this machine.
	for _, container := range m.Containers() {
		if err := i.machine(container); err != nil {
			return errors.Annotate(err, container.Id())
		}
	}
	return nil
}
