Container Ecosystem Trends You Need to Know

May 2, 2017

Since Docker launched in 2013, it has brought a level of excitement and innovation to software development that’s contagious. It has rallied support from every corner—enterprises to startups, developers to IT folk, plus the open source community, ISVs, the biggest public cloud vendors, and every tool across the software stack. Since the launch of Docker, many major milestones have served to advance the container revolution. Let’s look at some of them.

 

Container Orchestration Options

Getting started with your first container is fairly simple. All it takes is your laptop and a Docker client. However, running a microservices app is a whole other beast. The most difficult part is in creating, managing, and automating clusters of ephemeral containers.

The first major tool to address this challenge was Mesos with its Marathon orchestrator. Having powered distributed infrastructure even before Docker, Marathon is in use in production workloads at Twitter, and in other large-scale web applications.

The next orchestration tool to gain prominence was Kubernetes. In fact, today, Kubernetes leads the pack of Docker orchestration tools because of how extensible it is. It supports a broad list of programming languages, infrastructure options, and enjoys tremendous support from the container ecosystem. It isolates the application layer from the infrastructure layer, thus enabling true portability across multiple cloud vendors, and infrastructure setups. Read more


Unlocking the Business Value of Docker

April 25, 2017

Why Smart Container Management is Key

For anyone working in IT, the excitement around containers has been hard to miss.  According to RightScale, enterprise deployments of Docker over doubled in 2016 with 29% of organizations using the software versus just 14% in 2015 [1].  Even more impressive, fully 67% of organizations surveyed are either using Docker or plan to adopt it. While many of these efforts are early stage, separate research shows that over two thirds of organizations who try Docker report that it meets or exceeds expectations [2], and the average Docker deployment quintuples in size in just nine months.  Clearly, Docker is here to stay.

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


[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
