Docker announced today the general availability of Docker 1.13, the third major update of the open-source application container engine for GNU/Linux, macOS, and Microsoft Windows operating systems.

Docker 1.13 has been in development for the past couple of months, during which it received no less than seven RC (Release Candidate) versions that implemented numerous improvements for the new Swarm Mode introduced in Docker 1.12, a few security features, as well as a new Remote API (version 1.25) and Client.

"In Docker 1.13, the managed plugin api changed, as compared to the experimental version introduced in Docker 1.12. You must uninstall plugins which you installed with Docker 1.12 before upgrading to Docker 1.13. You can uninstall plugins using the 'docker plugin rm' command," read the release notes, which we've attached below.

The new Docker update is also here for those with New Year’s resolutions to build better and more reliable container applications, bringing them a restructured Docker CLI that now features a cleaned up syntax, easier-to-use commands, and improved help text. A total of 40 Docker commands are available in Docker 1.13.

Supports Ubuntu 16.10, Fedora 25, and Windows Server 2016

Among other noteworthy improvements implemented in Docker 1.13, we can mention various builder, plugins, volume, monitoring, and networking improvements, better CLI backward compatibility, the ability to use compose-files to deploy Swarm Mode services, and two new commands for seeing how much disk space Docker is using.

Docker 1.13 also adds support for building Docker DEB and RPM packages on the Ubuntu 16.10 (Yakkety Yak), Ubuntu 16.04 LTS (Xenial Xerus), and Fedora 25 operating systems for PPC64le (PowerPC 64-bit Little Endian) and s390x (IMB System z) architectures, and marks Docker for AWS and Docker for Azure as ready for production.
