Continental Innovates with Rancher and Kubernetes
Introduction A growing number of companies and individuals have become interested in deploying applications in containers. This article will walk those interested in Docker through the basic steps required to install the software and build containers. To make understanding the instructions a bit easier, we’re going to focus on just one of the many available Docker variants: Docker Community Edition (CE) on Ubuntu and CentOS Linux. We’ll also provide links to the installation page on the Docker website if you are running Windows, macOS, or other platforms.
Containers generally deploy faster and perform better than virtual machines. Visit Rancher to explore five tips for making Docker technology faster.
I’m pleased to announce that Rancher has released a new Terraform module for deploying Rancher on Google Compute Engine (GCE). This complements our existing module for Amazon Web Services (AWS). Terraform is an excellent tool for managing infrastructure as code, and many of our users already make use of it elsewhere in their environments. Using this module along with either GCE or AWS to orchestrate Rancher gives you the ability to define the entirety of the stack—from the application layer being managed by Docker Compose or Kubernetes resource YML in Rancher all the way down to the servers and networks in the Terraform plan.
Cyber security is no longer a luxury. If you need a reminder of that, just take a look at the seemingly endless number of stories appearing in the news lately about things like malware and security breaches. If you manage a Docker environment, and you want to help make sure your organization or users are not mentioned in the news stories that accompany the next big breach, you should know the tools available to you for helping to secure the Docker stack, and put them to work.
A provider of container management software, today announced they were recognized as one of four Cool Vendors in the May report by Gartner, Inc.
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.
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.
Last week Ivan Mikushin discussed adding system services to RancherOS using Docker Compose. Today I want to show you an exmaple of how to deploy Linux Dash as a system service. Linux Dash is a simple, low overhead, and web supported monitoring tool for Linux, you can read more about Linux Dash here. In this post i will add Linux Dash as a system service to RancherOS version 0.3.0 which allows users to add system services using rancherctl command.
Over the last few months our team at Rancher Labs has been working on building software that would allow users to create and manage persistent Docker volumes. With the release of Docker 1.8, which now officially supports Docker volume drivers, we announced Convoy, an open-source Docker volume driver that can snapshot, backup and restore Docker volumes anywhere. Convoy is designed to be a standalone Docker volume driver that runs on individual Linux hosts.
Hi, I’m Sidhartha Mani, one of the engineers at Rancher, and I wanted to provide a quick overview for how to get started using RancherOS. RancherOS is a micro-linux distribution that has the aim of providing just the right amount of OS to run Docker. It turns out, all Docker really requires to function is the kernel. RancherOS embraces this by running Docker as PID1 and everything running inside of it is a container.
Our team just spent the last 4 days in San Francisco attending the Dockercon conference and participating in the Hackathon. We decided to send the entire Rancher Labs engineering team to the conference. I’m so glad we did. There was big news and great new Docker capabilities. It gave us a chance to meet so many Rancher friends and users at one time. First there’s the city, the venue, the party, and the food.
Today Rancher Labs joins a group of industry leaders to create the Open Container Project(OCP). With OCP, the Docker container format and container runtime form the basis for an industry standard.
At Rancher Labs we decided early on to focus on developing our Rancher and RancherOS products specifically for Docker, even though the underlying technology can apply to other container formats as well. We are so excited about OCP because we can now focus on delivering the best user experience with a singular container standard knowing it will be supported by every major vendor in the industry.
Recently Rancher provided a disk image to be used to deploy RancherOS v0.3 on Google Compute Engine (GCE). The image supports RancherOS cloud config functionality. Additionally, it merges the SSH keys from the project, instance and cloud-config and adds them to the rancher user.
Building The Setup In this post, I will cover how to use the RancherOS image on GCE to set up a MongoDB Replica Set. Additionally I will cover how to use one of the recent features of Rancher platform which is the Load Balancer.

GlusterFS is a scalable, highly available, and distributed network file system widely used for applications that need shared storage including cloud computing, media streaming, content delivery networks, and web cluster solutions. High availability is ensured by the fact that storage data is redundant, so in case one node fails another will cover it without service interruption. In this post I’ll show you how to create a GlusterFS cluster for Docker that you can use to store your containers data.
Since I started playing with Docker I have been thinking that its network implementation is something that will need to be improved before I could really use it in production. It is based on container links and service discovery but it only works for host-local containers. This creates issues for a few use cases, for example when you are setting up services that need advanced network features like broadcasting/multicasting for clustering.
Rancher Server has recently added Docker Machine support, enabling us to easily deploy new Docker hosts on multiple cloud providers via Rancher’s UI/API and automatically have those hosts registered with Rancher. For now Rancher supports DigitalOcean and Amazon EC2 clouds, and more providers will be supported in the future. Another significant feature of Rancher is its networking implementation, because it enhances and facilitates the way you connect Docker containers and those services running on them.
As you may have seen, Rancher recently announced our integration with docker-machine. This integration will allow users to spin up Rancher compute nodes across multiple cloud providers right from the Rancher UI. In our initial release, we supported Digital Ocean. Amazon EC2 is soon to follow and we’ll continue to add more cloud providers as interest dictates. We believe this feature will really help the Zero-to-Docker _(and Zero-to-Rancher)_ experience. But the feature itself is not the focus of this post.
*This post is now a bit out of date. Since posting this article we’ve released the Rancher container management platform, and added full support for Mesos environments. You can read more about it at rancher.com/mesos. * In this tutorial, I will explain how to deploy a Mesos cluster in containers running on RancherOS and then make our deployment portable across different cloud platforms and virtualization systems. If you’re not familiar with Apache Mesos, it is an open-source project that provides an elastic and highly available clustering framework.
Kubernetes running as a system service on RancherOS from Ivan Mikushin (@imikushin) Yesterday, Ivan Mikushin did an excellent write up on deploying Kubernetes on RancherOS. I spent some time with it, and I think it illustrates some of the things we are most excited about with RancherOS. Specifically, in RancherOS we have a concept of system services that are deployed on a separate Docker daemon that we have called System Docker.
Today Docker acquired SDN software maker SocketPlane. Congratulations to both Docker and SocketPlane teams. We have worked closely with SocketPlane team since the early Docker networking discussions and have a great amount of respect for their technical abilities. We are also happy to see Docker Inc. make a serious effort to bring SDN capabilities to the Docker platform. Many customers have told us that the lack of multi-host networking is one of the last remaining gaps that impede the wide-spread production use of Docker containers.
In last week’s 0.9 release we added support in Rancher for users to create new deployment environments that can be shared with colleagues. These docker environments are called projects, and are an extension of the GitHub OAuth integration we added to Rancher last month. The focus of projects is to allow teams to collaborate on Docker environments, and since our user management is connected with GitHub today, we leverage standard GitHub abstractions, such as users, teams and organizations, to support Rancher Projects.

Magento is an open-source content management system (CMS) offering a powerful tool-set for managing eCommerce web-sites. Magento is used by thousands of companies including Nike and Office Max. Today we are going to walk through the process of setting up a Magento cluster using Docker and Rancher on the Amazon Elastic Compute Cloud (EC2).
Thanks to Docker, Orange and Blumberg Capital for hosting a great meetup last night in San Francisco. Darren Shepherd, Chief Architect of Rancher Labs introduced RancherOS for the first time, and answered questions from the audience. Learn more about
RancherOS, or download it from GitHub. If
you’d like to learn more, Darren will be presenting RancherOS at an online meetup on March 31st, 2015.

Today I would like to announce a new open source project called RancherOS – the smallest, easiest way to run Docker in production and at scale. RancherOS is the first operating system to fully embrace Docker, and to run all system services as Docker containers. At Rancher Labs we focus on building tools that help customers run Docker in production, and we think RancherOS will be an excellent choice for anyone who wants a lightweight version of Linux ideal for running containers.
