As the cloud-native ecosystem continues to evolve, many alternative solutions are popping-up, that challenges the status quo of application deployment methodologies. One of these solutions that is quickly gaining traction is Unikernels, which are executable images that can run natively on a hypervisor without the need for a separate operating system.

Kubernetes upgrades are always a tough undertaking when your clusters are running smoothly. Upgrades are necessary as every three months, Kubernetes releases a new version. If you do not upgrade your Kubernetes clusters, within a year, you can fall far behind. Rancher has always focused on solving problems, and they are at it again with a new open source project called System Upgrade Controller. In this tutorial, we will see how to upgrade a K3s Kubernetes cluster using System Upgrade Controller.

In this blog post, we are going to explain how to monitor Harbor container registry with Prometheus metrics. Harbor is an open-source container registry, originally developed by VMware and now under the CNCF umbrella. Although many of us typically use hosted container registries such as DockerHub, Quay, ECR, GCR, or ACR, when you need a self-hosted registry, Harbor is a great choice. Harbor provides great features such as RBAC, replication, and image scanning.

It’s one thing to build a Kubernetes log management strategy that only needs to support Kubernetes. But most organizations don’t have that luxury. They have log management practices already in place for other types of platforms or infrastructure, and they need to extend them to support Kubernetes. How can you do that in an efficient way? Keep reading for tips on integrating Kubernetes logging data into your existing log management workflow without rebuilding from the ground up.

Helm was born during the Pycon conference in 2013. Well, it wasn’t exactly Helm, it was Docker. It took Mr. Solomon Hykes a little over five minutes to completely change computing history. Ok, I admit that not everyone knows about -and uses- Docker and/or Kubernetes, but there is one fact that is undeniable: Helm in November 2019 had a million downloads and that is something important. We will see why.

Kubernetes (or “K8s”) is an open-source container orchestration tool developed by Google. In this tutorial, we will be leveraging the power of Kubernetes to look at how we can overcome some of the operational challenges of working with the Elastic Stack.

Sometimes technology partnerships are greater than the sum of their parts. That’s the case with two Swiss companies who have come together to deliver Kubernetes solutions to their customers. VSHN is Switzerland’s leading 24/7 cloud operations partner and first Kubernetes Certified Service Provider. amazee.io is an open source container hosting provider that offers flexible solutions built for speed, security and scalability.

Rancher Labs’ recent launch of Longhorn was in response to DevOps’ distress call for a cloud-native persistent storage solution for Kubernetes. At the time, industry pundit Chris Mellor posted that the company had entered into direct competition with its partners Portworx and Storage OS. A healthy dose of coopetition may be more like it.
