type CrossModelRelationsAPIv2

type CrossModelRelationsAPIv2 struct {
	*CrossModelRelationsAPIv3
}

CrossModelRelationsAPIv2 provides access to the CrossModelRelations API facade.

func (*CrossModelRelationsAPIv2) RegisterRemoteRelations

RegisterRemoteRelations sets up the model to participate in the specified relations. This operation is idempotent.

type CrossModelRelationsAPIv3

type CrossModelRelationsAPIv3 struct {
	// contains filtered or unexported fields
}

CrossModelRelationsAPIv3 provides access to the CrossModelRelations API facade.

func NewCrossModelRelationsAPI

func NewCrossModelRelationsAPI(
	st CrossModelRelationsState,
	fw firewall.State,
	resources facade.Resources,
	authorizer facade.Authorizer,
	authCtxt *commoncrossmodel.AuthContext,
	egressAddressWatcher egressAddressWatcherFunc,
	relationStatusWatcher relationStatusWatcherFunc,
	offerStatusWatcher offerStatusWatcherFunc,
	consumedSecretsWatcher consumedSecretsWatcherFunc,
) (*CrossModelRelationsAPIv3, error)

NewCrossModelRelationsAPI returns a new server-side CrossModelRelationsAPI facade.

func (*CrossModelRelationsAPIv3) PublishIngressNetworkChanges

func (api *CrossModelRelationsAPIv3) PublishIngressNetworkChanges(
	changes params.IngressNetworksChanges,
) (params.ErrorResults, error)

PublishIngressNetworkChanges publishes changes to the required ingress addresses to the model hosting the offer in the relation.

func (*CrossModelRelationsAPIv3) PublishRelationChanges

func (api *CrossModelRelationsAPIv3) PublishRelationChanges(
	changes params.RemoteRelationsChanges,
) (params.ErrorResults, error)

PublishRelationChanges publishes relation changes to the model hosting the remote application involved in the relation.

func (*CrossModelRelationsAPIv3) RegisterRemoteRelations

RegisterRemoteRelations sets up the model to participate in the specified relations. This operation is idempotent.

func (*CrossModelRelationsAPIv3) WatchConsumedSecretsChanges

WatchConsumedSecretsChanges returns a watcher which notifies of changes to any secrets for the specified remote consumers.

func (*CrossModelRelationsAPIv3) WatchEgressAddressesForRelations

func (api *CrossModelRelationsAPIv3) WatchEgressAddressesForRelations(remoteRelationArgs params.RemoteEntityArgs) (params.StringsWatchResults, error)

WatchEgressAddressesForRelations creates a watcher that notifies when addresses, from which connections will originate for the relation, change. Each event contains the entire set of addresses which are required for ingress for the relation.

func (*CrossModelRelationsAPIv3) WatchOfferStatus

func (api *CrossModelRelationsAPIv3) WatchOfferStatus(
	offerArgs params.OfferArgs,
) (params.OfferStatusWatchResults, error)

WatchOfferStatus starts an OfferStatusWatcher for watching the status of an offer.

func (*CrossModelRelationsAPIv3) WatchRelationChanges

func (api *CrossModelRelationsAPIv3) WatchRelationChanges(remoteRelationArgs params.RemoteEntityArgs) (
	params.RemoteRelationWatchResults, error,
)

WatchRelationChanges starts a RemoteRelationChangesWatcher for each specified relation, returning the watcher IDs and initial values, or an error if the remote relations couldn't be watched.

func (*CrossModelRelationsAPIv3) WatchRelationsSuspendedStatus

func (api *CrossModelRelationsAPIv3) WatchRelationsSuspendedStatus(
	remoteRelationArgs params.RemoteEntityArgs,
) (params.RelationStatusWatchResults, error)

WatchRelationsSuspendedStatus starts a RelationStatusWatcher for watching the life and suspended status of a relation.

type CrossModelRelationsState

type CrossModelRelationsState interface {
	common.Backend

	// Model returns the model entity.
	Model() (Model, error)

	// AddOfferConnection creates a new offer connection record, which records details about a
	// relation made from a remote model to an offer in the local model.
	AddOfferConnection(state.AddOfferConnectionParams) (common.OfferConnection, error)

	// IsMigrationActive returns true if the current model is
	// in the process of being migrated to another controller.
	IsMigrationActive() (bool, error)

	// GetSecretConsumerInfo returns the remote app tag and offer uuid
	// for the specified consumer app and relation tokens.
	GetSecretConsumerInfo(string, string) (names.Tag, string, error)

	// GetSecret gets the secret metadata for the given secret URI.
	GetSecret(*coresecrets.URI) (*coresecrets.SecretMetadata, error)

	// WatchConsumedSecretsChanges returns a watcher for secrets
	// consumed by the specified remote consumer.
	WatchConsumedSecretsChanges(string) (state.StringsWatcher, error)
}

CrossModelRelationsState provides the subset of global state required by the remote relations facade.
