type API Uses

type API struct {
    // contains filtered or unexported fields

API implements the API required for the model migration master worker.

) (*API, error)

NewAPI creates a new API server endpoint for the model migration master worker.

func NewFacade Uses

NewFacade exists to provide the required signature for API registration, converting st to backend.

func (*API) Export Uses

func (api *API) Export() (params.SerializedModel, error)

Export serializes the model associated with the API connection.

func (*API) MigrationStatus Uses

func (api *API) MigrationStatus() (params.MasterMigrationStatus, error)

MigrationStatus returns the details and progress of the latest model migration.

func (*API) MinionReports Uses

func (api *API) MinionReports() (params.MinionReports, error)

MinionReports returns details of the reports made by migration minions to the controller for the current migration phase.

func (*API) ModelInfo Uses

func (api *API) ModelInfo() (params.MigrationModelInfo, error)

ModelInfo returns essential information about the model to be migrated.

func (*API) Prechecks Uses

func (*API) SetPhase Uses

func (api *API) SetPhase(args params.SetMigrationPhaseArgs) error

SetPhase sets the phase of the active model migration. The provided phase must be a valid phase value, for example QUIESCE" or "ABORT". See the core/migration package for the complete list.

func (*API) SetStatusMessage Uses

func (api *API) SetStatusMessage(args params.SetMigrationStatusMessageArgs) error

func (api *API) WatchMinionReports() params.NotifyWatchResult

WatchMinionReports sets up a watcher which reports when a report for a migration minion has arrived.

type Backend Uses

type Backend interface {
    WatchForMigration() state.NotifyWatcher
    LatestMigration() (state.ModelMigration, error)
    ModelUUID() string
    ModelName() (string, error)
    ModelOwner() (names.UserTag, error)
