Functions

func AllowedContainerProvider

func AllowedContainerProvider(providerType storage.ProviderType) bool

AllowedContainerProvider returns true if the specified storage type can be used with a vm container. Currently, this is a very restricted list, just the storage types created on disk or in memory. In future we'll need to look at supporting passthrough/bindmount storage.

func CommonStorageProviders

func CommonStorageProviders() storage.ProviderRegistry

CommonStorageProviders returns a storage.ProviderRegistry that contains the common storage providers.

func NewManagedFilesystemSource

func NewManagedFilesystemSource(
	volumeBlockDevices map[names.VolumeTag]blockdevice.BlockDevice,
	filesystems map[names.FilesystemTag]storage.Filesystem,
) storage.FilesystemSource

NewManagedFilesystemSource returns a storage.FilesystemSource that manages filesystems on block devices on the host machine.

The parameters are maps that the caller will update with information about block devices and filesystems created by the source. The caller must not update the maps during calls to the source's methods.

func NewStorageProviderRegistry

func NewStorageProviderRegistry(reg storage.ProviderRegistry) storage.ProviderRegistry

NewStorageProviderRegistry returns a storage.ProviderRegistry that chains the provided registry with the common storage providers.
