Migrating a Rancher 2.1.x Single Node Installation to a High Availability Installation

Rancher offers two installation methods, single node and high availability. Single node installations allow users to quickly deploy a working Rancher 2 installation suitable for short-term development or proof-of-concept purposes. High availability deployments are significantly better suited for long-lived deployments of Rancher. Important Notes Migration from Single Node to HA is not supported by Rancher Labs You should be familiar with the Rancher architecture/troubleshooting in the event that you have issues during this process Prerequisites In order to migrate a single node Rancher installation to a high availability installation, a few facts must be true. 了解更多…

Herd your Rancher Labs multi-cloud strategy with Artifactory

DevOps engineers have grown so reliant on the power and scalability of Kubernetes (K8s) clusters that one server platform can seldom accommodate them all. More and more enterprises now run their containerized applications in clusters across multiple platforms at once, in public clouds and on-prem servers. That can fuel a chaotic stampede in an enterprise-class system - who has control, and which builds do you trust? Rancher offers a solution for managing multiple K8s clusters, and an enhanced Kubernetes distribution with additional features for central control of those clusters. 了解更多…

How to Get Started with Rancher’s New Multi-Tenant Prometheus Support and Alpha Release Process

I recently started at Rancher Labs as the Head of Product Management. I have been in the DevOps space since my time at VMware when we built Cloud Foundry back in 2011. But it wasn’t until 2014, that I started to look at Containers seriously. When Kubernetes launched the next year, it was clear that the enterprises need an easier way to deploy containers in their internal environments. I launched Qubeship. 了解更多…

Kubernetes on the Edge

Today we announced a partnership with Arm to create a Kubernetes-based platform for IoT, edge, and data center nodes, all powered by Arm servers. The platform includes a port of Rancher Kubernetes Engine (RKE) and RancherOS to Arm Neoverse-based servers. We have also enhanced Rancher 2.1 so that a single Rancher server can manage mixed x86 and Arm 64 nodes. Customers can therefore have x86 clusters running in the data center and Arm clusters running on the edge. 了解更多…

The Story of the First Kubernetes Critical CVE

CVE CVE-2018-1002105 was just announced in Kubernetes. I discovered this issue in early November, but the bug actually goes back a couple years and is a pretty interesting story and technical issue. Since this is the first critical CVE for Kubernetes, it is getting a lot of attention, but I don’t think it’s as bad as most people think. In fact, I think quite the opposite: this CVE shows how strong the community is and how well run it is. 了解更多…

Introduction to Kubernetes Monitoring

Introduction With over 40,000 stars on Github, more than 70,000 commits, and with major contributors like Google and Redhat, Kubernetes has rapidly taken over the container ecosystem to become the true leader of container orchestration platforms. Understanding Kubernetes and Its Abstractions At the infrastructure level, a Kubernetes cluster is a set of physical or virtual machines acting in a specific role. The machines acting in the role of Master act as the brain of all operations and are charged with orchestrating containers that run on all of the Nodes. 了解更多…
