Overview ¶
Package image provides underlying data types for Singularity image formats. Additionally, all image types will satisfy the ImageFormat{} interface. This interface will expose all things necessary to use a Singularity image, whether through OCI or directly.
type ImageFormat interface {
Root() *spec.Root - Root() returns the OCI compliant root of the
Image. This function may preform some action,
such as extracting the filesystem to a dir.
}
