Red Hat OpenShift Container Platform

This article shows how set up Microsoft SQL Server on Red Hat OpenShift and then use SQL Server to store data for a simple ASP.NET Core application running in a container deployed on OpenShift that manages a list of contacts. It also shows how to manage SQL Server within OpenShift using SQL Operation Studio.

If MongoDB's WiredTiger memory cache in Red Hat Mobile Application Platform (RHMAP) consumes all the memory available for a container, memory issues and Nagios alerts will occur. This article describes how to configure the WiredTiger memory cache to prevent high-usage memory issues and Nagios alerts.

This post is the first in a series that examines new trends in modern application development and whether Kubernetes is "the new application server."

Using the Horizontal Pod Autoscaler to autoscale Red Hat Cache Service is a nice way to increase overall system capacity depending on the load. The autoscaler monitors the amount of memory used by the container and adds or removes Cache Service pods based on this measurement. This article provides a demo of how to use the autoscaler to autoscale Red Hat Cache Service.

Sabre recently announced it has chosen Red Hat OpenShift Container Platform to fuel its digital transformation as it exits from transaction processing on the mainframe with TPF. OpenShift will be the basis of its next-generation platform, which will include microservices, DevOps, and a multi-faceted cloud strategy, to revolutionize the travel business.

Kestrel, the web server in the .NET Core, supports replacing the network layer. This article benchmarks Kestrel’s networking layer with a Linux-specific implementation to achieve measurable performance gains compared to the out-the-box implementation.

The next online DevNation Live is July 19th at 12pm EDT for "Container pipeline master: Continuous integration + continuous delivery with Jenkins", presented by Red Hat principal technical product marketing manager, Siamak Sadeghianfar.

In this article, I show how you can call the Red Hat OpenShift REST API from your C# code, which is useful for automating tasks. Visual Studio is used to take the REST API definition and create a library you can use in your code. Also shown is how to handle the conversion needed for the JSONpath components.

Learn how to process and aggregate huge streams of IoT data using Strimzi and Apache Kafka on Red Hat OpenShift. The data stream is processed using the Red Hat AMQ distributed streaming platform to perform aggregations in real time as data is ingested into the application.

This article demonstrates how to implement a contract-first API design using Apicurio and Red Hat Fuse. It shows how to create an OpenAPI standard document as a contract between API providers and consumers using Apicurio and how to quickly create mock tests using Red Hat Fuse.

Listen to a podcast that discusses some of the basics, lessons learned, and other things you can use to “fast-track” what you need to be successful with Kubernetes.

Containers are the new way of deploying applications. They are an efficient way to portably deploy applications across clouds and different OSes.This article looks at what OpenShift brings for .NET Core specifically and how OpenShift provides a DevOps platform on top of Kubernetes for building and deploying apps.

Kubernetes and related technologies, such as Red Hat OpenShift and Istio, provide the non-functional requirements that used to be part of an application server and the additional capabilities described in this article. Does that mean application servers are dead?

Here are behind-the-scenes details on how the Red Hat Summit 2018 multi-cloud demo was configured to run Red Hat Data Grid in active-active-active mode for cross-site replication across three clouds to handle a large amount of globally routed traffic.

Learn how to remotely debug an ASP.NET Core container pod on Red Hat OpenShift using Visual Studio from a Windows computer.

While it's easy to get started with containers, best practices (as usual) require more forethought and planning. In this post, Scott McCarty and Ben Breard share their experience and wisdom to smooth your move into the world of containers.

See how the Kafka-CDI library can handle difficult setup tasks and make creating Kafka-powered event-driven applications for MicroProfile and Jakarta EE very easy.

Learn how to create an Ansible Playbook Bundle (APB) and customize it to configure an external remote host (through SSH), explore what goes on "under the hood," and get tips for troubleshooting APBs.

Using Meta Test Family, writing tests for containers is really easy. Container testing helps you guarantee that a container is working properly just as an RPM package would.

Serverless computing (often called Functions as a Service, or FaaS) is one of the hottest emerging technologies today. The OpenWhisk project, currently in incubation at Apache, is an open-source implementation of serverless that lets you create functions that are invoked in response to events.

OpenShift.io is a cloud native set of zero-install tools for editing and debugging code, agile planning, and managing CI/CD pipelines. Installing and configuring developer tools is a major time sink; OpenShift.io takes that task out of the picture.

At Red Hat Summit 2018, Red Hat’s John Osborne and Microsoft’s Harold Wong gave a talk: Developing .NET Core Applications on Red Hat OpenShift. .NET Core 1.0 availability for Linux was announced two years ago, but many developers still have a number of questions about the differences between .NET Framework and .NET Core.
