MicroK8s now native on Windows and macOS

Windows and macOS developers can now use MicroK8s natively! Use kubectl at the Windows or Mac command line to interact with MicroK8s locally just as you would on Linux. Clean integration into the desktop means better workflows to dev, build and test your containerised apps. MicroK8s is a conformant upstream Kubernetes, packaged for simplicity and resilience. It provides sensible defaults and bundles the most commonly used components for at-your-fingertips access.

Longhorn: Rancher's Journey from Zero to GA

When Frodo was commissioned on a seemingly straightforward journey to retrieve the One Ring, I doubt he realized the adventure and commitment he was embarking on. Rancher Labs started on a similarly daring journey almost four years ago. It didn’t take a wizard showing up uninvited at dinner to convince us of this. From the beginning of Rancher Labs, our founding team had a deep conviction about the importance of storage in the future of cloud-first computing.

Longhorn Simplifies Distributed Block Storage in Kubernetes

Today we’re announcing the general availability of Longhorn, an enterprise-grade, cloud-native container storage solution. Longhorn directly answers the need for an enterprise-grade, vendor-neutral persistent storage solution that supports the easy development of stateful applications within Kubernetes. We’ve been working on Longhorn for almost as long as we’ve been around as a company.

Datadog on Kubernetes

When 2 years ago Datadog decided to move its infrastructure platform to Kubernetes we didn’t expect to find so many roadblocks, but ingesting trillions of datapoints per day in a reliable fashion requires pushing the limits of cloud computing. Creating and managing dozens of clusters, with thousands of nodes each and operating in several clouds was a challenging but rewarding learning experience. In this episode Ara Pulido, Developer Advocate, will chat with Laurent Bernaille, Staff Engineer at Datadog and part of the team that created Datadog’s Kubernetes platform. We’ll cover the challenges we found creating and scaling Datadog’s Kubernetes platform and how we overcame them.

KMC - Running a Multi-Cluster Service Mesh in Rancher

If you are or your organization is running Kubernetes, then it's likely that you are running more than one cluster. This model works well for most, but starts to break down when microservices and service mesh enter the discussion. However, with some additional configuration and tooling , a multicluster mesh can take advantage of distributed Kubernetes environments and the services therein. In this Master Class, recorded on June 20, 2020, Rancher Field Engineer Jason Skrzypek discusses and demos a multi-cluster service mesh running Istio.

Introduction to KUDO: Automate Day-2 Operations (II)

In a previous article, we discussed KUDO and the benefits of it when you want to create or manage Operators. In this article we will focus on how to start to work with KUDO: Installation, using a predefined Operator and create your own one. Installing KUDO To install KUDO the first step is to install the CLI plugin in order to manage KUDO via CLI. Depending on your OS you can use a package manager like Brew or Krew, however installing the binary is a straightforward option to proceed.

Everything You Need to Know about Kubernetes Services Networking in Your Rancher Cluster

As a leading, open-source multi-cluster orchestration platform, Rancher lets operations teams deploy, manage and secure enterprise Kubernetes. Rancher also gives users a set of CNI options to choose from, including open-source Project Calico.

CVE-2020-8555 And What We've Done About It

A security vulnerability (CVE-2020-8555) with a Medium severity has been reported that affects following versions of Kubernetes: Note, an attack using this vulnerability requires permission to create a pod or StorageClass and would typically only be granted to internal administrators or developers within an organization. It is possible to mitigate an attack by implementing policies using Gatekeeper and restricting StorageClass using Kubernetes access controls.
