Intro to k3s Lightweight Kubernetes Online training

Earlier this year, Rancher Labs introduced k3s, a new open source project which is a lightweight implementation of Kubernetes that is easy to install and can run on x86 and ARM infrastructure with only 512 MB of RAM required to run it. It is geared towards teams that need to deploy applications quickly and reliably to resource-constrained environments. Some use cases for k3s are edge, Single Board Computers, IoT, and CI.

Authentication and Authorization for multiple Kubernetes clusters with Rancher

A Kubernetes cluster is a collection of resources running across multiple nodes. Managing these resources also entails granting and controlling users' access to them. Different teams could be running their applications on the same cluster. Configuring RBAC is essential when it comes to such multi-tenant setups. Grouping resources into namespaces and giving certain teams access to them is a good start. Rancher leverages this to more effectively group the cluster's resources into larger subsets called projects.

And Then There Were Three -- IBM, VMWare, and Rancher

When we started Rancher in 2014, our vision was to enable enterprise IT to procure and utilize computing resources (“cattle”) from any infrastructure provider. We were extremely lucky to be able to leverage wonderful technologies like Kubernetes which made computing resources consistent across all infrastructure providers.

Zero to k3s Kubeconfig in seconds with k3sup

k3sup: From zero to KUBECONFIG in < 1 min K3s is an open-source, lightweight Kubernetes distribution by Rancher that was introduced this year and has gained huge popularity. People not only like the concept behind it, but also the awesome work that the team has done to strip down the heavy Kubernetes distribution to a minimal level. Though k3s started as a POC project for local Kubernetes development, its development has led people to use it even at a production level.

Intro to Rio Online Training: The MicroPaaS for Kubernetes

We recently launched Rio, a new open-source project. It is a MicroPaaS built on top of Kubernetes, Istio, Knative, and Prometheus. You can use it to build, test, deploy, scale, and version stateless apps on any standard Kubernetes cluster, which means that you can run your apps the way you want to without having to spend time wiring them together. Join this session to see a live demo of the product features and capabilities.

Kubernetes Master Class - DevOps Alerting and Visualization with Prometheus and Grafana

In this presentation by Rancher Director of Community Jason van Brackel, you will learn how to setup alerts with Rancher and Prometheus Alert Manager to find problems before there's an outage. You'll also learn to visualize metrics for Kubernetes and for your applications so you can gather new insights to your users' usage patterns and your applications' run-time behaviors.

Code Commits: only half the story

It’s not the first time I’ve been asked by a sales rep the following question: “The customer has looked at Stackalytics and is wondering why Rancher doesn’t have as many code commits as the competition. What do I say?” For those of you unfamiliar with Stackalytics, it provides an activity snapshot, a developer selfie if you will, of commits and lines of code changed in different open source projects.
