the class PullBaseImageStep method getCachedBaseImages.

/**
 * Retrieves the cached base images. If a base image reference is not a manifest list, returns a

 * platforms in the manifest list but only when all of the images are cached.
 *
 * @return the cached images, if found
 * @throws IOException when an I/O exception occurs
 * @throws CacheCorruptedException if the cache is corrupted
 * @throws LayerPropertyNotFoundException if adding image layers fails
 * @throws BadContainerConfigurationFormatException if the container configuration is in a bad
 *     format
 * @throws UnlistedPlatformInManifestListException if a cached manifest list has no manifests
 *     matching the configured platform
