Docker 1.13 - Docker meetup février 2017
The document summarizes changes in Docker 1.13, including restructuring the CLI to group related commands together and improve usability. A newer Docker CLI can now communicate with older daemon versions. Docker 1.13 introduces secret management capabilities for swarm clusters and allows using Compose files with the docker stack command to deploy to swarms.
