Rio is an application deployment engine 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.

As enterprises accelerate their adoption of containers and Kubernetes, they need to take necessary steps to protect such a critical part of their compute infrastructure. But not everyone has the same security needs, with developers and engineers often asking for different levels of granular control on specific configurations. This masterclass will help you navigate these conversations using Rancher’s current best practice security guidance. Topics to be covered will include:

As DevOps teams deploy Kubernetes in production using Rancher, enterprises must focus on the runtime security and compliance requirements of their cloud-native platforms. Starting with Rancher 2.2, we published self-assessment and hardening guides to outline provisioning a cluster to comply with the CIS Kubernetes benchmark. Identifying gaps and pain points in the process, Rancher engineering added additional features to both Rancher and RKE to simplify the process.

Ready to get some training on using K3s, the lightweight Kubernetes distribution? K3s 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.

This class assumes you have participated in the original Rancher Labs K3s online training or that you have previously installed K3s with multiple worker nodes. Watch the intro training here:

Rancher Engineer Hussein Galal explores how Rancher Kubernetes Engine (RKE) was designed and the internals of how RKE work.

In this Kubernetes Master Class, Rancher Engineers Hussein Galal and Sebastiaan van Steenis will explore how RKE was designed, the internals of how RKE works, and how Rancher and RKE work together. This session is suited for anyone who wants to learn more about what happens under the hood when you either use Rancher or RKE to provision and maintain clusters.

As organizations adopt Kubernetes as the de facto standard for container orchestration, operational challenges remain, particularly as enterprises look beyond their hybrid cloud environments to the Edge.

I had the opportunity to talk with Dax McDonald, one of the principal developers of Rio, and had him walk me through an introduction to Rio, the new dashboard, and how to get started using it with a standard Dockerfile and the new Riofile.
