Functions ¶
func DetectCompression ¶
DetectCompression returns the compression type based on file extension.
func DetectImageSource ¶
func DetectImageSource(ref string) (types.ImageSource, error)
DetectImageSource detects the image type and returns an appropriate ImageSource.
func DownloadToFile ¶
func DownloadToFile(ctx context.Context, url, destPath string, onProgress ProgressFunc) error
DownloadToFile downloads a URL to a local file with optional progress reporting.
func FindInitrdPath ¶
FindInitrdPath searches for initrd in common locations.
func FindKernelPath ¶
FindKernelPath searches for kernel in common locations.
func OpenDecompressed ¶
func OpenDecompressed(path string) (io.ReadCloser, int64, error)
OpenDecompressed opens a file and returns a decompressed reader. Returns the reader, uncompressed size (-1 if unknown), and error.
