Rancher 2.4

Take Hybrid-Cloud Kubernetes to the Edge

Edge scalability, zero downtime maintenance, enhanced security, and new hosted option

What’s New in Rancher 2.4

From Web Scale to Edge Scale

Kubernetes is accelerating hybrid cloud innovation in every market segment. By placing cluster operations physically closer to remote devices, lightweight distributions like K3s have become a key ingredient to a successful edge strategy.

With Rancher 2.4, enterprises can now run 1000s of production-grade Kubernetes clusters at the edge to maximize operational efficiency, satisfy ultra-low latency requirements, and allow their DevOps teams to move faster and with even greater agility.

Zero Downtime Maintenance for RKE

Customers expect your containerized applications to be available all the time and DevOps teams are expected to deploy new versions of them several times a day.

Rancher 2.4 now supports rolling updates of worker nodes running RKE. This makes it easy for operators to select and configure an upgrade strategy so that DNS and Ingress experience zero downtime during cluster updates.

Production-grade Security with CIS Scan

Rancher enhances Kubernetes’ native capabilities to give enterprise users what they need to secure production-grade deployments from datacenter to cloud to edge.

Rancher 2.4’s CIS Scan feature now assesses your RKE clusters against the 100+ tests of the CIS Benchmark for Kubernetes with just a few clicks. It reveals what matches security best practices and what needs to be updated to reduce risk and transform any Kubernetes security posture.

Hosted Rancher

As a 'white glove’ DevOps service for the Rancher control plane, Hosted Rancher is ideal for enterprises that just want to focus on day-2 Kubernetes cluster operations.

Let our experts minimize the operational overhead of installing, upgrading, securing and scaling Rancher whilst you maintain full access to your downstream Kubernetes clusters.

Built using our reference architecture and available with our 99.9% uptime SLA, Hosted Rancher the fastest path to production Kubernetes.

“Right now, we don’t have a standardized branch office setup – we need different components for different locations. We use physical servers now, and it requires an engineer to install hardware, configure the OS and install the apps, which can take up to five days at a cost of about $2,000 U.S. With Rancher 2.4, K3s can be preloaded onto the server, booted remotely through PXE, and auto-joined to the Rancher Kubernetes environment for remote management."

Zak Anderson, head of container platform management at Africa’s second largest bank - ABSA

"We are looking forward to upgrading our clusters with zero downtime. Right now Rancher simply shuts down all nodes during an upgrade. A milestone ending in 2.4 allows the sequential reboot and upgrade of each node which is a feature that we are sorely missing right now.”

Philippe-Michael Radl, Systems Engineer at mobile payments provider DIMOC

How does Rancher 2.4 address the challenges of enterprises running multi-cluster Kubernetes on-premises, in the cloud and at the edge?

Kubernetes enables a common compute platform across any infrastructure and a consistent set of infrastructure capabilities including improved reliability, enhanced security and increased operational efficiencies. But as organizations adopt Kubernetes, clusters are often deployed with limited access to shared tooling and services, inconsistent security policies and no centralized cluster operations.

This latest release enhances Rancher’s ability to address these challenges with the following new features:
