Containerize .NET for Red Hat OpenShift: Linux containers and .NET Core

Containerize .NET for Red Hat OpenShift: Linux containers and .NET Core

When .NET was released to the open source world (November 12, 2014—not that I remember the date or anything), it didn’t just bring .NET to open source; it brought open source to .NET. Linux containers were one of the then-burgeoning, now-thriving technologies that became available to .NET developers. At that time, it was “docker, docker, docker” all the time. Now, it’s Podman and Buildah, and Kubernetes, and Red Hat OpenShift, and serverless, and … well, you get the idea. Things have progressed, and your .NET applications can progress, as well.

This article is part of a series introducing three ways to containerize .NET applications on Red Hat OpenShift. I’ll start with a high-level overview of Linux containers and .NET Core, then discuss a couple of ways to build and containerize .NET Core applications and deploy them on OpenShift.

Red Hat CodeReady Workspaces provides teams with predefined workspaces to streamline application development. Out of the box, CodeReady Workspaces supports numerous languages and plugins. However, many organizations want to customize a workspace and make it available to developers across the organization as a standard. In this article, I show you how to use a custom devfile registry to customize a workspace for C++ development. Once that’s done, we will deploy an example application using Docker.

Strapi is the leading open-source headless content management system (CMS). It’s 100% JavaScript, fully customizable, and takes a developer-first approach. Strapi provides you with an interface to create and manage all the resources for your website. You can then build a front end to connect to your Strapi API with your favorite tools and frameworks. Content editors can use the friendly administration panel to manage and distribute content. Strapi is also based on a plugin system, which makes the CMS flexible and extensible.

Quarkus is already fast, but what if you could make inner loop development with the supersonic, subatomic Java framework even faster? Quarkus 1.5 introduced fast-jar, a new packaging format that supports faster startup times. Starting in Quarkus 1.12, this great feature became the default packaging format for Quarkus applications. This article introduces you to the fast-jar format and how it works.

Design event-driven integrations with Kamelets and Camel K

Design event-driven integrations with Kamelets and Camel K

By Pasquale Congiusti

The Kamelet is a concept introduced near the end of 2020 by Camel K to simplify the design of complex system integrations. If you’re familiar with the Camel ecosystem, you know that Camel offers many components for integrating existing systems. An integration’s granularity is related to its low-level components, however. With Kamelets you can reason at a higher level of abstraction than with Camel alone.

A Kamelet is a document specifying an integration flow. A Kamelet uses Camel components and enterprise integration patterns (EIPs) to describe a system’s behavior. You can reuse a Kamelet abstraction in any integration on top of a Kubernetes cluster. You can use any of Camel’s domain-specific languages (DSLs) to write a Kamelet, but the most natural choice is the YAML DSL. The YAML DSL is designed to specify input and output formats, so any integration developer knows beforehand what kind of data to expect.

A Kamelet also serves as a source or sink of events, making Kamelets the building blocks of an event-driven architecture. Later in the article, I will introduce the concept of source and sink events and how to use them in an event-driven architecture with Kamelets.

Deploy integration components easily with the Red Hat Integration Operator

Deploy integration components easily with the Red Hat Integration Operator

Any developer knows that when we talk about integration, we can mean many different concepts and architecture components. Integration can start with the API gateway and extend to events, data transfer, data transformation, and so on. It is easy to lose sight of what technologies are available to help you solve various business problems. Red Hat Integration‘s Q1 release introduces a new feature that targets this challenge: the Red Hat Integration Operator.
