Forrester identifies Rancher as a Leader in Enterprise Container Management.

Last week we got some exciting news here at Rancher, when the analyst firm Forrester published a report that identified Rancher as in its “leaders” category for Enterprise Container Management Software. Rancher was identified as a leader along with Docker Enterprise Edition and RedHat OpenShift, and was specifically called out for excelling in providing multi-cluster Kubernetes management. The analysts ranked Docker EE first giving it high marks for supporting both Swarm and Kubernetes and providing leadership for the Docker open source community, and scored OpenShift highly for how well it integrates with the RedHat ecosystem of products, and for providing an integrated developer experience.

Challenges and Solutions for Scaling Kubernetes in the Hybrid Cloud

Challenges and Solutions for Scaling Kubernetes in the Hybrid Cloud

Introduction Let’s assume you’re in business online: you have your own datacenter and a private cloud running your website. You’ll have a number of servers deployed to run applications and store their data. The overall website traffic in this scenario is pretty constant, yet there are times where you expect traffic growth. How do you handle all this growth in traffic? The first thing that comes to mind is that you need to be able to scale some of your applications in order to cope with the traffic increase. Read More…

Migrating Applications from Rancher 1.6 to Rancher 2.0: Walkthrough Video

Rancher 2.0 was rearchitected with the goal of providing a complete multi-cluster management solution for Kubernetes and Docker containers. Because of these changes, there is no direct upgrade path from Rancher 1.6 to Rancher 2.x. This demonstration video guides users through migrating Rancher 1.6 applications to Rancher 2.x. There are several other important resources to utilize: October Online Meetup: Migrating from Rancher 1.6 to Rancher 2.0 In our October Online Meetup, we will dive into how to transition various aspects of Rancher 1.

The Unexpected Kubernetes: Part 2: Volume and Many Ways of Persisting Data

Recap Last time we talked about PV, PVC, Storage Class and Provisioner. To quickly recap: Originally PV was designed to be a piece of storage pre-allocated by administrator. Though after the introduction of Storage Class and Provisioner, users are able to dynamically provision PVs now. PVC is a request for a PV. When used with Storage Class, it will trigger the dynamic provisioning of a matching PV. Read More…

Kubernetes versus Docker: What's the difference?

Docker vs Kubernetes: The Journey from Docker to Kubernetes The need to deploy applications from one computing environment to another quickly, easily, and reliably has become a critical part of enterprise’s business requirements and DevOps team’s daily workflow. It’s unsurprising then, that container technologies, which make application deployment and management easier for teams of all sizes, have risen dramatically in recent years. At the same time, however, virtual machines (VM) as computing resources have reached their peak use in virtualized data centers. Read More…

Introduction to Container Security

Containers are still a relatively new technology, but they have already had a massive impact on software development and delivery. Companies all around the world are starting to migrate towards microservices, and containers enable developers to quickly spin up services with minimal effort. In the past it took a fair amount of time to download, install, and configure software, but now you can take advantage of solutions that have already been packaged up for you and only require a single command to run.

Setup a basic Kubernetes cluster with ease using RKE

In this post, you will go from 3 Ubuntu 16.04 nodes to a basic Kubernetes cluster in a few simple steps. To accomplish this, you will be using Rancher Kubernetes Engine (RKE). To be able to use RKE, you will need 3 Linux nodes with Docker installed (see Requirements below). This won’t be a production ready cluster, but enough to get you familiar with RKE, some Kubernetes and be able to play around with the cluster. Read More…

The Unexpected Kubernetes: Part 1: PV, PVC, Storage Class and Provisioner

Foreword Anyone who has followed the cloud computing area in recent years would notice and probably get involved in the rise of Docker and Kubernetes. Today, the Cloud’s Big Three (Google, Amazon, Microsoft) all offer managed Kubernetes services on top of their traditional public cloud services. Powerful, scalable, resilient, in many people’s mind, Kubernetes is becoming the ultimate answer to cloud computing. And yet I am not so sure about Kubernetes, even though it builds upon 15 years of experience of running production workloads at Google(btw, it’s a great paper, I’ve read it multiple times).

Using RKE to Deploy a Kubernetes Cluster on Exoscale

Introduction One of the biggest challenges with Kubernetes is bringing up a cluster for the first time. There have been several projects that attempt to address this gap including kmachine and minikube. However, both assume you are starting from a blank slate. What if you have your instances provisioned, or have another means of provisioning hosts with configuration management? This is the problem that the people at Rancher are solving with the Rancher Kubernetes Engine or RKE. Read More…
