Docker2aci is a CLI binary that converts Docker images to ACI (https://github.com/appc/spec/blob/master/SPEC.md#app-container-image). It takes as input either a file generated by "docker save" or a Docker registry URL. It gets all the layers of a Docker image and squashes them into an ACI image. Optionally, it can generate one ACI for each layer, setting the correct dependencies.
