Containers

Red Hat Container Development Kit (CDK) 3.6 is now available to run an OpenShift/Kubernetes cluster on your laptop for developing cloud- and container-based applications.

Given Kubernetes, docker containers and service mesh, are we seeing the start of an imminent decline in the use of application servers? This article explores the use case for application servers and examines why they will continue to evolve.

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.

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

In this DevNation Live session, we’ll look into how you can build an automated continuous integration and continuous delivery Jenkins pipeline.

Podman is an alternative to the Docker command-line interface that lets you run standalone, daemonless containers. See examples of how easy it is to use Podman.

This post provides an example of how to configure role-based access control on top of Red Hat AMQ--a flexible, high-performance messaging platform that provides a role-based security model with built-in support for separation of duties.

It can be complex to set up an end-to-end integration test infrastructure, but the process can be simplified by using an infrastructure-as-code approach. In addition, running integration tests for multiple OS/browser combinations can waste resources and time, but a container orchestrator and ephemeral workloads can help mitigate that. This article shows how to build behavior-driven development (BDD) container-native integration tests and run them in OpenShift to overcome these obstacles.

Serverless architectures can benefit from faster startup times. The configuration demonstrated in this article shows how GraalVM can reduce startup time and Docker image size for Java-based programs hosted on container platforms such as Red Hat OpenShift Containter Platform.

Registration for DevConf.US, a great open source Red Hat–sponsored community technology conference for contributors to Free and Open Source Software (FOSS) and those who want to learn more about it, is now open and the schedule is live.

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.

Istio Pool Ejection allows you to temporarily block under- or non-performing pods from your system.

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?

This video demonstrates how Istio Route Rules work with kubernetes (and OpenShift) to route traffic between microservices without any code changes.

Monitoring the Red Hat AMQ 7 broker enables you to get metrics about the performance and behavior of the broker and its resources. This post describes how to set up Red Hat AMQ 7 for monitoring the broker using the popular jmxtrans agent for Java-based applications.

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.

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.

Senior Director Stephanos Bacon discussed the changing developer landscape and the factors that influence it. As cloud computing becomes ubiquitous and serverless continues to grow, more changes are in store.

You're in an IT department. How does the rest of the organization see you? As a valuable asset whose code and APIs make a difference in the marketplace, or as a necessary evil that should be trimmed wherever possible? Containers, microservices, and serverless computing can get you where you need to go.

About a year ago Red Hat announced its participation as a launch partner of the Istio project. We are now introducing the istiooc command-line tool and a set of pre-built Istio and Jaeger example scenarios that would make it even easier to get started with these technologies.

We are excited to announce a Developer Preview of AMQ Streams, a new addition to Red Hat AMQ, focused on running Apache Kafka on OpenShift. AMQ Streams simplifies the deployment, configuration, management and use of Apache Kafka on OpenShift using automation based on Kubernetes Operators.

The past nine weeks of blog posts have introduced, explained, and demonstrated some of the many features of the Istio service mesh when combined it is with Red Hat OpenShift and Kubernetes. This, the final post in this series, is a recap.
