Functions ¶
func GenerateACI ¶
func GenerateACI(layerNumber int, layerData types.DockerImageData, dockerURL *types.ParsedDockerURL, outputDir string, layerFile *os.File, curPwl []string, compression common.Compression) (string, *schema.ImageManifest, error)
GenerateACI takes a Docker layer and generates an ACI from it.
func GenerateACI22LowerLayer ¶ added in v0.12.0
func GenerateACI22LowerLayer(dockerURL *types.ParsedDockerURL, layerDigest string, outputDir string, layerFile *os.File, curPwl []string, compression common.Compression) (string, *schema.ImageManifest, error)
func GenerateACI22TopLayer ¶ added in v0.12.0
func GenerateACI22TopLayer(dockerURL *types.ParsedDockerURL, imageConfig *typesV2.ImageConfig, layerDigest string, outputDir string, layerFile *os.File, curPwl []string, compression common.Compression, lowerLayers []*schema.ImageManifest) (string, *schema.ImageManifest, error)
func GenerateEmptyManifest ¶ added in v0.12.0
func GenerateEmptyManifest(name string) (*schema.ImageManifest, error)
func GenerateManifest ¶
func GenerateManifest(layerData types.DockerImageData, dockerURL *types.ParsedDockerURL) (*schema.ImageManifest, error)
GenerateManifest converts the docker manifest format to an appc ImageManifest.
func GenerateManifestV22 ¶ added in v0.12.0
func GenerateManifestV22(name string, dockerURL *types.ParsedDockerURL, config *typesV2.ImageConfig, imageDigest string, lowerLayers []*schema.ImageManifest) (*schema.ImageManifest, error)
func ValidateACI ¶
ValidateACI checks whether the ACI in aciPath is valid.
func WriteManifest ¶
func WriteManifest(outputWriter *tar.Writer, manifest schema.ImageManifest) error
WriteManifest writes a schema.ImageManifest entry on a tar.Writer.
func WriteRootfsDir ¶
WriteRootfsDir writes a "rootfs" dir entry on a tar.Writer.
Types ¶
type Docker2ACIBackend ¶
type Docker2ACIBackend interface {
GetImageInfo(dockerUrl string) ([]string, *types.ParsedDockerURL, error)
BuildACI(layerIDs []string, dockerURL *types.ParsedDockerURL, outputDir string, tmpBaseDir string, compression common.Compression) ([]string, []*schema.ImageManifest, error)
}
Docker2ACIBackend is the interface that abstracts converting Docker layers to ACI from where they're stored (remote or file).
GetImageInfo takes a Docker URL and returns a list of layers and the parsed Docker URL.
BuildACI takes a Docker layer, converts it to ACI and returns its output path and its converted ImageManifest.
