Docker 1.9 ships with production-ready Swarm and multi-host networking

Editor: Docker 1.9 was released yesterday November 3 2015. This is a link to the official release announcement.

The big news is that Swarm, the container clustering component, is now production-ready. And multi-host networking is now supported.

But that’s not all, because other components, like Docker Compose, also got new features.

Here’s an excerpt from the release announcement.

Docker Swarm and multi-host networking are production-ready, Docker Engine has a new volume management system, and Docker Compose has much better support for multiple environments. These in combination establish the foundation for scaling your distributed apps in production.

Containerization is changing how you build infrastructure, and you need to use the right tools for the job. Docker Swarm turns your infrastructure into a single pool of resources for running your distributed apps, but all of the containers that are part of those apps need managing somehow. And they all probably need to talk to each other.

And some of them probably need to store data somewhere. In a world where a container could be running on any host in your infrastructure, this is a difficult thing to manage.

Needless to say, we’ve got you covered. Docker Networking allows you create virtual networks that span underlying hosts, so your containers can communicate with each wherever they are. The new volume management system in Docker Engine lets you store persistent data wherever those containers land. On top of these fundamentals, you can then use Compose to run the important bit: your application.
