Docker 1.13 introduced significant changes to its command-line interface (CLI) to improve usability and consistency, addressing issues present in the previous version. The update includes the introduction of management commands, where similar functionalities are grouped under logical categories such as "container," "image," and "network," which simplifies navigation and reduces confusion for users. This approach replaces the earlier system of numerous top-level solo commands, which were inconsistent and challenging for beginners. In addition to improved command structure, Docker 1.13 maintains backward compatibility while encouraging users to transition to the new commands. The release also includes features like Compose file support for deploying Swarm mode services, CLI reorganization, and enhancements in monitoring and build processes. For those interested in exploring the new features, resources such as online meetups and tutorial videos are available, along with Docker compatibility for both Mac and Windows platforms.
