A single manifest is information about an image, such as layers, size, and digest. The docker manifest command also gives users additional information such as the os and architecture an image was built for. A manifest list is a list of image layers that is created by specifying one or more (ideally more than one) image names. It can then be used in the same way as an image name in docker pull and docker run commands, for example.

Docker Content Trust (DCT) provides the ability to use digital signatures for data sent to and received from remote Docker registries. These signatures allow client-side or runtime verification of the integrity and publisher of specific image tags.
