Docker Releases v1.12 – Built-in Orchestration Ready for Production
We wanted to thank everyone in the community for helping us achieve this great milestone of making Docker 1.12 generally available for production environments. Docker 1.12 adds the largest and most sophisticated set of features into a single release since the beginning of the Docker project. Dozens of engineers, both Docker employees and external contributors, have made substantial contributions to every aspect of 1.12 orchestration including core algorithms, integration into the Docker Engine, documentation and testing.
We’re very grateful to the community, which has helped us with feedback, bug reports and new ideas. We couldn’t have done it without the help in particular of the tens of thousands of Docker for Mac and Windows beta users who have been testing our 1.12 features since DockerCon in June. We’ve seen contributions ranging from bash tab completion to UX up-and-down votes that helped us understand what users want most. Compared to what we unveiled at DockerCon, we’ve ended up with significant improvements in the swarm node join workflow (it’s simpler), error reporting (easier to view), UX improvements (more logical), networking (fixed reliability issues) etc.
The core team also wanted to give a special thanks to one of our external maintainers and Docker Captain, Chanwit Kaewkasi, who through his own undertaking, drove the amazing DockerSwarm2000 initiative which rallied the entire community around scaling an RC of 1.12 with swarm mode to nearly 2.4K nodes and just under 100K containers. This was achieved through our global community, who donated access to their machines in all shapes and sizes from bare metal, to Raspberry Pis, to various clouds to VMs from x86 architectures to ARM-based systems. Through this evaluation using live data, we identified that built-in orchestration in Docker has already–in its first release–doubled Docker’s orchestration scale in just a half a year. While this validates the scalability of the architecture, there is still headroom for greater performance optimization in the future.
