if (manifest.isError()) {
return Failure(
"Failed to get dependencies for image id '" + imageId +
"': " + manifest.error());
}
vector<Image::Appc> dependencies;
foreach (const spec::ImageManifest::Dependency& dependency,
manifest->dependencies()) {
Image::Appc appc;
appc.set_name(dependency.imagename());
if (dependency.has_imageid()) {
appc.set_id(dependency.imageid());
}
// TODO(jojy): Make Image::Appc use appc::spec::Label instead of
// mesos::Label so that we can avoid this loop here.
foreach (const spec::ImageManifest::Label& label, dependency.labels()) {
mesos::Label appcLabel;
appcLabel.set_key(label.name());
appcLabel.set_value(label.value());
