This guide will show you how to run the newly GA’ed bits of MicroShift on a Raspberry Pi 4 using Fedora IoT 38 or 39. It can announce routes via mDNS so hosting applications in an mDNS aware LAN is a breeze. THIS IS COMPLETELY UNSUPPORTED. DON’T EVEN THINK OF RED HAT SUPPORT WHEN YOU […]
tl;dr It’s no surprise that developers are looking for ways to include powerful new technologies like AI Assistants to improve their workflow and productivity. However, many companies are reluctant to allow such technology due to concerns about privacy, security and IP law. This article addresses the concerns about privacy and security and describes how to […]
This blog elaborates on how to discover issues before they occur and have a quicker root cause detection.
React on exception right away in an automated fashion. And with that reduce operational costs and enable faster delivery and MTRS time.
How can we ensure the security of our supply chain and verify that all container images deployed in our Kubernetes clusters are both signed and protected, preventing the deployment of malicious ones? What methods can we adopt to sign and verify container images within our CI/CD pipelines, thereby bolstering the security of our DevOps workflows? […]
In most Kubernetes installations, a well-maintained etcd is one of the key conditions for having a peaceful administrator life. Most Kubernetes distributions imply limitations on etcd and its size. For Openshift there’s a quota limit of 8GB. Typically that limitation should not hit you unless you run really large clusters and or utilize the cluster […]
Photo by Daniel van den Berg on Unsplash On a warm summer day, I visited the Kubernetes Community Days Munich and enjoyed Adrian Reber’s talk about “Forensic container checkpointing and analysis”. Now I want to try that with OpenShift 4.13! This blog post will mainly cover how to enable and use checkpointing on OpenShift 4.13. […]
This article shows how MuleSoft’s Runtime Fabric (RTF) deployed to Red Hat OpenShift delivers a modern containerized API solution.
Introduction As a Solution Architect for Red Hat’s ecosystem, I talk to many independent software vendors (ISVs) about modernizing their applications to enable hybrid cloud and edge strategies. Linux, containers, Kubernetes and micro-services architecture are a default choice nowadays in many new application development projects. But sometimes you can not get rid of some dependencies […]
Introduction Since my last exploration of the topic in mid-2021, there have been significant advancements in cold disaster recovery for applications on Kubernetes. Since then, there have been remarkable improvements in both the technical aspects and the user experience of cold disaster recovery. Notably, the Kubernetes operator that manages the technical infrastructure for cold disaster […]
By Robert Baumgartner, Red Hat Austria, February 2023 (OpenShift 4.12) In this blog I will guide you on how to use service performance monitoring (SPM) with Jaeger. It should work with any application that is working with OpenTelemetry. This document is based on OpenShift 4.12. See Distributed tracing release notes. OpenShift distributed tracing platform Operator […]
