Do Edge Applications Need Stateful Storage?

Kubernetes applications are increasingly making their way to the edge and embedded computing. Storage will quickly follow as the applications that rely on this edge infrastructure become more advanced and naturally carry more state. According to a study by McKinsey and Company, a “connected car” processes up to 25GB of data per hour.

Rancher Online Meetup: January 2021 - k3d: Local Development with K3s Made Easy

In this meetup we'll show you how to get productive developing locally on Kubernetes with the help of k3d which lets you spin up a K3s cluster on your laptop. We'll guide you through a full development setup including the k3d CLI, the awesome new vscode-k3d plugin and synergy with tools like Skaffold or Tilt.

Compute Confidently at the Edge with Rancher and Longhorn 1.1

Today’s announcement of Longhorn 1.1, a Cloud Native Computing Foundation (CNCF) Sandbox project, is exciting news for users of Rancher, SUSE’s Kubernetes management platform, and the Kubernetes community. Longhorn is an enterprise-grade, cloud native container storage solution that went GA in June 2020. Since then, adoption has increased by 235 percent.

Using Hybrid and Multi-Cloud Service Mesh Based Applications for Distributed Deployments

Service Mesh is an emerging architecture pattern gaining traction today. Along with Kubernetes, Service Mesh can form a powerful platform which addresses the technical requirements that arise in a highly distributed environment typically found on a microservices cluster and/or service infrastructure. A Service Mesh is a dedicated infrastructure layer for facilitating service-to-service communications between microservices.

Set up K3s in High Availability using k3d

Have you ever wanted to try K3s high availability cluster “mode,” and you either did not have the minimum three “spare nodes” or the time required to set up the same amount of VMs? Then you are in for a good treat: meet k3d! If you’re not familiar with k3d, its name gives you a hint to what it’s all about: K3s in Docker.

November Meetup - GitOps with Rancher Continuous Delivery

As the number of clusters under management increase, application owners and cluster operators need a programatic way to manage deploying to their clusters. Rancher Continuous Delivery allows an administrator to create groups of clusters and link them to Git repositories. This means an application owner only ever needs access to the Git repository and not the management cluster. Deployment manifests can be defined in Helm, Kustomize or K8s yaml files and can be tailored based on attributes of the target clusters.

September 2020 Online Meetup - What's New with K3s?

If you haven't heard, Rancher's K3s was accepted last month as a Sandbox Project by the CNCF! Exciting things have been underway with K3s and in this September's meetup we will bring you up to speed on all of them. We’ll discuss the donation of K3s to the CNCF and talk about the changes you can expect to see as part of this move. Rancher experts will also cover the features and enhancements available in the 1.19 release. The focus of the 1.19 release has been improved configurability and operations for K3s clusters.

Rancher Online Meetup - December 2020: Open Source Hyperconverged Infrastructure

Learn about a new project we’ve been working on at Rancher Labs! Harvester is a virtualization and HCI platform that uses open-source hypervisors and other CNCF technologies to produce a seamless experience for administrators of complex environments that depend on Virtual Machines. Join Harvester’s principal engineer Sheng Yang and product manager William Jimenez as they walk you through the new tech.

Mitigating Kubernetes Security Vulnerability when using ExternalIP Services (CVE-2020-8554)

Earlier this month the Kubernetes project discovered a security issue affecting multitenant clusters: If a potential attacker can already create or edit services and pods, then they may be able to intercept traffic from other pods (or nodes) in the cluster. An attacker that is able to create a ClusterIP service and set the spec.externalIPs field can intercept traffic to that IP.
