What is Rancher?

This video provides a short introduction to Rancher, the world’s most widely deployed Kubernetes management platform. With Rancher, IT organizations can deploy, manage and secure any Kubernetes deployment regardless of where it is running. Best of all, Rancher is intuitive to use, and built to support DevOps teams, as they use containers to automate operations and move to continuous delivery. Rancher is 100% free and open source.

Why SUSE Acquired Rancher Labs

My favorite ice cream store is just off Richmond Green, close to where I live in West London. On sunny days, locals queue around the block to buy their fantastic gelatos and sorbets. Every one of their customers knows that they could easily nip into the supermarket around the corner to buy hermetically sealed chocolate ice cream, but they queue anyway. Why?

Now GA: Data-in-Transit Encryption in Calico v3.15

We’re excited to announce that the latest release of Calico includes encryption for data-in-transit. Calico is the open source networking and network security solution for containers, virtual machines, and host-based workloads, offering connectivity and security for container workloads. One of Calico’s best-known security features is its implementation of Kubernetes Network Policy, providing a way to secure container workloads by restricting traffic to and from trusted sources.

MicroK8s HA tech preview is now available

High availability (HA) for MicroK8s, the lightweight Kubernetes, is now available as a tech preview for Linux, Windows and macOS. The Kubernetes control plane can now be distributed across multiple nodes, bringing resiliency to the cluster while maintaining a low footprint using Dqlite, the distributed SQL engine as the Kubernetes datastore.

How to monitor Golden signals in Kubernetes

What are Golden signals metrics? How do you monitor golden signals in Kubernetes applications? Golden signals can help to detect issues of a microservices application. These signals are a reduced set of metrics that offer a wide view of a service from a user or consumer perspective, so you can detect potential problems that might be directly affecting the behaviour of the application.

Monitoring Kubernetes in Production

Monitoring Kubernetes, both the infrastructure platform and the running workloads, is on everyone’s checklist as we evolve beyond day zero and into production. Traditional monitoring tools and processes aren’t adequate, as they do not provide visibility into dynamic container environments. Given this, what tools can you use to monitor Kubernetes and your applications?

Best practices for alerting on Kubernetes

Create Reproducible Security in Kubernetes with Helm 3 and Helm Charts

With the growing popularity of containerized applications, organizations and startups at all levels need to manage their Kubernetes deployments more safely at scale. Today, there is an expanding list of tools and services that can help do this. One of these services is the package manager known as Helm.

Chaos Engineering for a More Secure Kubernetes

Netflix, Amazon, Google, Facebook, and a host of other companies have adopted chaos engineering, which encourages designing systems to proactively ward off potential issues through testing and the anticipation of failure. When it comes to container orchestration tools like Kubernetes, chaos engineering is a vital tactic for enhancing security.
