BuildACI takes an input directory that conforms to the ACI specification, and outputs an optionally compressed ACI image.

func ExtractLayerInfo

func ExtractLayerInfo(store *store.Store, in string) (types.Dependency, error)

ExtractLayerInfo extracts the image name and ID from a path to an ACI

func ExtractLayers

func ExtractLayers(store *store.Store, in string) (types.Dependencies, error)

ExtractLayers extracts layers from an ACI and treats its rootfs as the last layer

func GetManifestFromImage

func GetManifestFromImage(in string) (*schema.ImageManifest, error)

getManifestfromImage extracts the image manifest of an ACI given by a path

func GetStore

func GetStore() (*store.Store, error)

func GetStoreWithPath

func GetStoreWithPath(path string) (*store.Store, error)

func GetTmpStore

func GetTmpStore() (*store.Store, error)

func Hash

func Hash(strings ...string) (string, error)

Hash takes an array of strings and returns their hash.

func OverwriteManifest

func OverwriteManifest(in io.ReadSeeker, out io.Writer, manifest *schema.ImageManifest) error

OverwriteManifest takes an ACI and outputs another with the original manifest overwritten by the given manifest.

func PrepareACIDir

func PrepareACIDir(manifest *schema.ImageManifest, rootfs string) (string, error)

PrepareACIDir takes a manifest and a path to rootfs and lay them out in a temp directory that conforms to the layout of ACI image.
