The top-level docker deploy command (using the "Docker Application Bundle" (.dab) file format was introduced as an experimental feature in Docker 1.13 / 17.03, but superseded by support for Docker Compose files (and docker app / CNAB).
With no development being done on this feature, and no active use of the file format, we will be removing support for the DAB file format, and the top-level docker deploy command (hidden by default in 19.03 through #1602), in favour of docker stack deploy using compose files.
