Rancher and the Moby Project

April 21, 2017

This week, the Moby Project was introduced with the idea of componentizing Docker into a series of assemblies. At DockerCon, a neat demo was done using the moby tool to assemble various components into customized Linux operating system images. While very cool, this seemed to have confused people – we’d like to provide some more background and explanation about the Moby Project and how it affects Rancher, RancherOS, and our users.

 

Some background on the Moby Project

The transition to the Moby Project actually started a couple of months ago, with a discussion among the Docker Project maintainers, about the dual nature of Docker as both a product and a project. This dual nature served Docker (the project and the company) well in the beginning, but at the end of the day, Docker, Inc. must make hard decisions about what their product should and will be. As a group of maintainers, we agreed that the product and project should be split. Read more


DockerCon 2017 – Thoughts and Impressions

We’ve just returned from DockerCon 2017, which was a fantastic experience. I thought I’d share some of my thoughts and impressions of the event, including my perspective on some of the key announcements, while they are still fresh in my mind.

New open source projects

Container adoption for production environments is very real.  The keynotes on both days included some exciting announcements that should further accelerate adoption in the enterprise as well as foster innovation in the open source community.  Day 1 included demos of multi-stage docker builds (introduced in Docker 17.04), which is an incredibly cool feature.

During the keynote, Docker also announced two new open source projects for system builders who want to create their own modular container-based systems.  With the Moby Project, Docker has essentially created a Fedora/RHEL split that enables users to build container-based systems from a component library and reference blueprints. Darren Shepherd, Chief Architect at Rancher Labs, provides some more background and explanation about the Moby Project and how it affects Rancher, RancherOS, and our users here. Read more


[Press Release] Rancher Labs Partners with Docker to Embed Docker Enterprise Edition into Rancher Platform

April 18, 2017

Docker Enterprise Edition technology and support now available from Rancher Labs

Cupertino, Calif. – April 18, 2017 – Rancher Labs, a provider of container management software, today announced it has partnered with Docker to integrate Docker Enterprise Edition (Docker EE) Basic into its Rancher container management platform. Users will be able to access the usability, security and portability benefits of Docker EE through the easy to use Rancher interface. Docker provides a powerful combination of runtime with integrated orchestration, security and networking capabilities. Rancher provides users with easy access to these Docker EE capabilities, as well as the Rancher platform’s rich set of infrastructure services and other container orchestration tools. Users will now be able to purchase support for both Docker Enterprise Edition and the Rancher container management platform directly from Rancher Labs. Read more


Announcing Longhorn: an open source project for microservices-based distributed block storage

April 17, 2017

I’m super excited to unveil Project Longhorn, a new way to build distributed block storage for cloud- and container-based deployments. Following the principles of microservices, we have leveraged containers to build distributed block storage out of small independent components, and use container orchestration to coordinate these components to form a resilient distributed system.

Why Longhorn?

To keep up with the growing scale of cloud- and container-based deployments, distributed block storage systems are becoming increasingly sophisticated. The number of volumes a storage controller serves continues to increase.  While storage controllers in the early 2000s served no more than a few dozen volumes, modern cloud environments require tens of thousands to millions of distributed block storage volumes. Storage controllers have therefore become highly complex distributed systems. Read more


[Press Release] RancherOS Hits General Availability

April 12, 2017

Rancher Labs delivers fast, ultra-lightweight container operating system

Cupertino, Calif. – April 12, 2017 Rancher Labs, a provider of container management software, today announced the general availability of RancherOS, a simplified Linux distribution built from containers, for containers. RancherOS eliminates any unnecessary libraries and services, resulting in a footprint three times smaller than that of other container operating systems. The simplified container environment reduces container boot time, increases efficiency and improves security by reducing the number of components that can be exploited.

“At BRCloud Services, we strive to deliver the best solutions to address our customers’ needs,” said Helvio Lima, CEO at BRCloud Services. “RancherOS epitomizes what modern infrastructure should look like. We’re thrilled to integrate the container operating system into our portfolio.”

RancherOS makes it simple to run containers at scale in development, test and production. By containerizing system services and leveraging Docker for management, the operating system provides an incredibly reliable and simple to manage container-ready environment. System services are defined by Docker Compose and automatically configured using cloud-init, reducing administrative burden. Unneeded libraries and services are eliminated, significantly reducing the OS footprint and minimizing the hassle of updating, patching and maintaining a container host operating system. Containers running on RancherOS boot in seconds, making the operating system ideal for running microservices or auto-scaling. Teams can use the Rancher container management platform to easily manage RancherOS at large scale in production. Read more
