Functions

func Finalize

func Finalize(ctx context.Context) error

TODO: figure out why the Init calls are wrapped in once.Do - implies it can be called multiple times, but once Finalize is called things will not be functional.

func Init

func Init(ctx context.Context, session *session.Session, imgStoreURL *url.URL) error

Init will initialize the package vars and create the default portLayerKV store

Note: The imgStoreURL is provided by the portlayer init function and is currently based on the image-store specified at appliance creation via vic-machine. That URL is the starting point for the datastore persistence path and does not mean that the k/v stores are presisted w/the images.

func NewDatastoreKeyValue

func NewDatastoreKeyValue(ctx context.Context, session *session.Session, name string) (kvstore.KeyValueStore, error)

NewDatastoreKeyValue will validate the supplied name and create a datastore backed key / value store

The file will be located at the init datastoreURL -- currently that's in the appliance directory under the {dsFolder} folder (i.e. [datastore]vch-appliance/{dsFolder}/{name})

func Store

func Store(name string) (kvstore.KeyValueStore, error)

Store will return the requested store

Types

type StoreManager

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