Types ¶
type Backend ¶
type Backend interface {
Filesystem(names.FilesystemTag) (state.Filesystem, error)
VolumeAttachment(names.Tag, names.VolumeTag) (state.VolumeAttachment, error)
WatchMachineFilesystems(names.MachineTag) state.StringsWatcher
WatchUnitFilesystems(tag names.ApplicationTag) state.StringsWatcher
WatchMachineFilesystemAttachments(names.MachineTag) state.StringsWatcher
WatchUnitFilesystemAttachments(names.ApplicationTag) state.StringsWatcher
WatchModelFilesystems() state.StringsWatcher
WatchModelFilesystemAttachments() state.StringsWatcher
WatchModelVolumeAttachments() state.StringsWatcher
}
Backend provides access to filesystems and volumes for the filesystem watchers to use.
type Watchers ¶
type Watchers struct {
Backend Backend
}
Watchers provides methods for watching filesystems. The watches aggregate results from host- and model-scoped watchers, to conform to the behaviour of the storageprovisioner worker. The model-level storageprovisioner watches model-scoped filesystems that have no backing volume. The host-level worker watches both host-scoped filesystems, and model-scoped filesystems whose backing volumes are attached to the host.
func (Watchers) WatchMachineManagedFilesystemAttachments ¶
func (fw Watchers) WatchMachineManagedFilesystemAttachments(m names.MachineTag) state.StringsWatcher
WatchMachineManagedFilesystemAttachments returns a strings watcher that reports lifecycle changes for attachments to both machine-scoped filesystems, and model-scoped, volume-backed filesystems that are attached to the specified machine.
func (Watchers) WatchMachineManagedFilesystems ¶
func (fw Watchers) WatchMachineManagedFilesystems(m names.MachineTag) state.StringsWatcher
WatchMachineManagedFilesystems returns a strings watcher that reports both machine-scoped filesystems, and model-scoped, volume-backed filesystems that are attached to the specified machine.
func (Watchers) WatchModelManagedFilesystemAttachments ¶
func (fw Watchers) WatchModelManagedFilesystemAttachments() state.StringsWatcher
WatchModelManagedFilesystemAttachments returns a strings watcher that reports lifecycle changes to attachments of model-scoped filesystem that have no backing volume. Volume-backed filesystems are always managed by the host to which they are attached.
func (Watchers) WatchModelManagedFilesystems ¶
func (fw Watchers) WatchModelManagedFilesystems() state.StringsWatcher
WatchModelManagedFilesystems returns a strings watcher that reports model-scoped filesystems that have no backing volume. Volume-backed filesystems are always managed by the host to which they are attached.
func (Watchers) WatchUnitManagedFilesystemAttachments ¶
func (fw Watchers) WatchUnitManagedFilesystemAttachments(app names.ApplicationTag) state.StringsWatcher
WatchUnitManagedFilesystemAttachments returns a strings watcher that reports lifecycle changes for attachments to both unit-scoped filesystems, and model-scoped, volume-backed filesystems that are attached to units of the specified application.
func (Watchers) WatchUnitManagedFilesystems ¶
func (fw Watchers) WatchUnitManagedFilesystems(app names.ApplicationTag) state.StringsWatcher
WatchUnitManagedFilesystems returns a strings watcher that reports both unit-scoped filesystems, and model-scoped, volume-backed filesystems that are attached to units of the specified application.
