Automate DNS Configuration with ExternalDNS

One of the awesome things about being in the Kubernetes community is the constant evolution of technologies in the space. There’s so much purposeful technical innovation that it’s nearly impossible to keep an eye on every useful project. One such project that recently escaped my notice is the ExternalDNS subproject. During a recent POC, a member of the organization to whom we were speaking asked about it. I promised to give the subproject a go and I was really impressed.

Some of the cool new features that have been introduced in Rancher 2.0 include Cluster and Workload Alerting. These features were frequently asked for under 1.x, so were high on the feature list for when we started development on 2.0. This article will focus exclusively on the new Alerting features, but is part of a series that will cover additional new aspects of Rancher 2.0. NOTIFIERS The Alerting feature lets you create customised alerts and have those alerts sent to a number of backend systems.


Load Balancing on Kubernetes with Rancher

When it comes to containerizing user applications and deploying them on Kubernetes, incremental design is beneficial. First you figure out how to package your application into a container. Then, decide on a deployment model – do you want one container or multiple ones – any other scheduling rules, and configuring liveness and readines probes so that if the application goes down, Kubernetes can safely restore it. The next step would be to expose the workload internally and/or externally, so that the workload can be reached by microservices in the same Kubernetes cluster, or - if it’s a user facing app - from the internet.

Rancher is a popular open source tool used by many organizations to manage Kubernetes clusters. With the latest release of EKS in GA, Rancher is excited to announce integration with the new managed Kubernetes cluster solution by AWS. We are excited about the availability of EKS because most Rancher users run their clusters on AWS. In the past, they had to create and manage their own clusters using Rancher’s own RKE distribution or open source tools like Kops.

Etcd is a highly available distributed key-value store that provides a reliable way to store data across machines, more importantly it is used as a Kubernetes’ backing store for all of a cluster’s data. In this post we are going to discuss how to backup etcd and how to recover from a backup to restore operations to a Kubernetes cluster. Etcd in Rancher 1.6 In Rancher 1.6 we use our own Docker image for etcd which basically pulls the official etcd and adds some scripts and go binaries for orchestration, backup, disaster recovery, and healthcheck.

With the latest release of RancherVM, we’ve added the ability to schedule virtual machines (guests) to specific Kubernetes Nodes (hosts). This declarative placement (in Kubernetes terms: required node affinity) can be modified at any time. For stopped VMs, no change will be observed until the VM starts. For running VMs, the VM will enter a migrating state. RancherVM will then migrate the running guest machine from old to new host.

Like many of us in the Kubernetes space, I’m excited to check out the shiny new thing. To be fair, we’re all working with an amazing product that is younger than my pre-school aged daughter. The shiny new thing at KubeCon Europe was a new container runtime authored by Google named gVisor. Like a cat to catnip, I had to check this out and share it with you. What is gVisor?

Don’t have access to Cloud infrastructure? Maybe you would like to use Rancher for local development just like you do in production? No problem, you can install Rancher 2.0 on your desktop. In this tutorial we will install Docker-for-Desktop Edge release and enable the built in Kubernetes engine to run your own personal instance of Rancher 2.0 on your desktop. Prerequisites For this guide you will need a couple of tools to manage and deploy to your local Kubernetes instance.

A few months ago, we announced the Rancher Kubernetes Engine (RKE). RKE is a new open source project we have been working on in Rancher to provide a Kubernetes installer that is simple to use, fast and can be used anywhere. You can read more about the project here. We have been working on adding more functionality and enable more deployment options with each RKE release. One of the most notable features we rolled out recently was initial support for Kubernetes Cloud Providers.

After a fantastic week at KubeCon in Europe, I spent Monday morning commuting into the office and reflecting on some of the interesting discussions I had over three surprisingly sunny days in Copenhagen. It was an important event for us at Rancher, we rolled out Rancher 2.0 to general availability, and met with hundreds of Kubernetes users who were attending the event trying to learn about the latest approaches to leveraging Kubernetes to adopt cloud native architectures.
