Having trouble deploying Kubernetes in a highly available mode and have a backing remote database? This blog is for you. I will explain how to deploy K3s in HA configuration with an external database Postgres. K3s is a certified Kubernetes distribution for IoT and Edge computing. I deployed it on virtual machines in an IBM Z mainframe. Instead of etcd, I choose Postgres as my storage for my K3s clusters. I deployed Postgres in non HA mode.
One of the best things about Kubernetes is just how absurdly flexible it is. You, as an admin, can shape what gets deployed into what is the best for your business. Whether this is a basic webapp with just a deployment, service and ingress; or if you need all sorts of features with sidecars and network policies wrapping the serverless service-mesh platform of the day. The power is there.
After these last releases Kubewarden now has support for verifying the integrity and authenticity of artifacts within Kubewarden using the Sigstore project. In this post, we shall focus on verifying container image signatures using the new verify-image-signatures policy. To learn more about how Sigstore works, take a look at our previous post
With KubeCon underway, many of us in the cloud native community are looking forward to learning about the newest innovations from the companies we follow. At SUSE, we’ve been working hard to deliver some new enhancements to Rancher with our 2.6.5 version. I want to briefly take you through the highlights of this release and why we’re excited about these new additions.
There are many different ways to run a Kubernetes cluster, from setting everything up manually to using a lightweight distribution like K3s. K3s is a Kubernetes distribution built for IoT and edge computing and is excellent for running on low-powered devices like Raspberry Pis. However, you aren’t limited to running it on low-powered hardware; it can be used for anything from a Homelab up to a Production cluster.
Epinio takes developers from application to URL in one step. In this blog post, I’m going to tell you about the new Epinio extension for Docker Desktop, that allows you to run Epinio on your laptop. DevOps are very interested in the details of containerized workloads and Kubernetes especially, but for developers, the abstraction layer provided by Kubernetes might not be too relevant to their daily work.
With recent releases, the Kubewarden stack supports verifying the integrity and authenticity of content using the Sigstore project. In this post, we focus on Kubewarden Policies and how to create a Secure Supply Chain for them.
Rancher Desktop is an all-in-one solution for container management on your desktop workstation. It provides an easily maintained Kubernetes installation that runs on your local machine and streamlines setting up containerized workflows in development. Assembling a Kubernetes cluster from scratch can be daunting, because multiple components must work in unison. With Rancher Desktop, you get everything preconfigured with one software download.
When I left Red Hat to join SUSE as a Technical Marketing Manager at the end of 2021, I heard about Harvester, a new Hyperconverged Infrastructure (HCI) solution with Kubernetes under the hood. When I started looking at it, I immediately saw use cases where Harvester could really help IT operators and DevOps engineers. There are solutions that offer similar capabilities but there’s nothing else on the market like Harvester.
