Functions

func RegisterExport

func RegisterExport(coordinator Coordinator, clock clock.Clock, logger logger.Logger)

RegisterExport registers the export operations with the given coordinator.

func RegisterImport

func RegisterImport(coordinator Coordinator, clock clock.Clock, logger logger.Logger)

RegisterImport register's a new model migration importer into the supplied coordinator.

Types

type Coordinator

type Coordinator interface {
	Add(modelmigration.Operation)
}

Coordinator is the interface that is used to add operations to a migration.

type ExportService

type ExportService interface {
	// AllMachineNames returns the names of all machines in the model.
	AllMachineNames(ctx context.Context) ([]coremachine.Name, error)
	// InstanceID returns the cloud specific instance id for this machine.
	// If the machine is not provisioned, it returns a NotProvisionedError.
	InstanceID(ctx context.Context, machineUUID string) (instance.Id, error)
	// HardwareCharacteristics returns the hardware characteristics of the
	// specified machine.
	HardwareCharacteristics(ctx context.Context, machineUUID string) (*instance.HardwareCharacteristics, error)
	// GetMachineUUID returns the UUID of a machine identified by its name.
	// It returns a [github.com/juju/juju/domain/machine/errors.MachineNotFound]
	// if the machine does not exist.
	GetMachineUUID(ctx context.Context, name coremachine.Name) (string, error)
}

ExportService defines the machine service used to export machines to another controller model to this controller.

type ImportService

type ImportService interface {
	// CreateMachine creates the specified machine.
	CreateMachine(ctx context.Context, machineName machine.Name) (string, error)
	// SetMachineCloudInstance sets an entry in the machine cloud instance table
	// along with the instance tags and the link to a lxd profile if any.
	SetMachineCloudInstance(ctx context.Context, machineUUID string, instanceID instance.Id, displayName string, hardwareCharacteristics *instance.HardwareCharacteristics) error
}

ImportService defines the machine service used to import machines from another controller model to this controller.
