How to install Ansible Tower on Red Hat OpenShift

How to install Ansible Tower on Red Hat OpenShift

In this article, I will show how to install and manage Red Hat Ansible Tower on Red Hat OpenShift Container Platform. Ansible Tower helps you scale IT automation, manage complex deployments, and improve productivity. You can centralize and control your IT infrastructure with a visual dashboard, and it provides role-based access control, job scheduling, integrated notifications, graphical inventory management, and more.

As you may know, Ansible Tower 3.3, the latest release of this automation platform, was released a few weeks ago and added new features. From the release notes you’ll see that Ansible Tower 3.3 added support for a container-based installation on top of OpenShift or Kubernetes.

In this blog, we’ll see how easy it is to set up Ansible Tower 3.3 on OpenShift and have it running as a container in just a few minutes.

Welcome Apache Kafka to the Kubernetes Era!

Welcome Apache Kafka to the Kubernetes Era!

We have pretty exciting news this week as Red Hat is announcing the General Availability of their Apache Kafka Kubernetes operator. Red Hat AMQ Streams delivers the mechanisms for managing Apache Kafka on top of OpenShift, our enterprise distribution for Kubernetes.

Everything started last May 2018 when David Ingham (@dingha) unveiled the Developer Preview as new addition to the Red Hat AMQ offering. Red Hat AMQ Streams focuses on running Apache Kafka on OpenShift. In the microservices world, where several components need to rely on a high throughput communication mechanism, Apache Kafka has made a name for itself for being a leading real-time, distributed messaging platform for building data pipelines and streaming applications.

Modern web applications on OpenShift: Part 2 — Using chained builds

Modern web applications on OpenShift: Part 2 — Using chained builds

In the previous post, we took a quick look at a new source-to-image (S2I) builder image designed for building and deploying modern web applications on OpenShift. While the last post was focused on getting your app deployed quickly, this post will look at how to use the S2I image as a “pure” builder image and combine it with an OpenShift chained build.

Introduction to Linux interfaces for virtual networking

Introduction to Linux interfaces for virtual networking

Linux has rich virtual networking capabilities that are used as basis for hosting VMs and containers, as well as cloud environments. In this post, I will give a brief introduction to all commonly used virtual network interface types. There is no code analysis, only a brief introduction to the interfaces and their usage on Linux. Anyone with a network background might be interested in this blog post. A list of interfaces can be obtained using the command ip link help.

This post covers the following frequently used interfaces and some interfaces that can be easily confused with one another:

After reading this article, you will know what these interfaces are, what’s the difference between them, when to use them, and how to create them.

Modernize your application deployment with Lift and Shift

Modernize your application deployment with Lift and Shift

For many software modernization projects, it’s all about learning to love, lift, and shift. No, wait. It’s all about learning to love lift and shift. The basic idea behind lift and shift is to modernize how an existing application is packaged and deployed. Because it’s not about rewriting the application itself, lift and shift is typically quick to implement.

Modern development environments rely on containers for packaging and deployment. A modern environment also uses a continuous integration / continuous deployment (CI/CD) system that automatically builds, tests, and deploys an application whenever its source code changes.

Announcing: Thorntail 2.2 General Availability

Announcing: Thorntail 2.2 General Availability

An Introduction to Thorntail

Today Red Hat is making Thorntail 2.2 generally available to Red Hat customers through a subscription to Red Hat OpenShift Application Runtimes (RHOAR). RHOAR provides application developers with a variety of application runtimes running on the OpenShift Container Platform.

Thorntail is the new name for WildFly Swarm, and bundles everything you need to develop and run Thorntail and MicroProfile applications by packaging server runtime libraries with your application code and running it with java -jar. It speeds up the transition from monoliths to microservices and takes advantage of your existing industry standard Java EE technology experience.

Deploying MicroProfile apps on Microsoft Azure using the Azure Open Service Broker

Deploying MicroProfile apps on Microsoft Azure using the Azure Open Service Broker

At the recently concluded Microsoft Ignite 2018 conference in Orlando, I had the honor of presenting to a crowd of Java developers and Azure professionals eager to learn how to put their Java skills to work building next-gen apps on Azure. Of course, that meant showcasing the technology coming out of the popular MicroProfile community, in which Red Hat plays a big part (and makes a fully supported, productized MicroProfile implementation through Thorntail, part of Red Hat OpenShift Application Runtimes).

We did a demo too, which is the main topic of this blog post, showing how easy it is to link your Java MicroProfile apps to Azure services through the Open Service Broker for Azure (the open source, Open Service Broker-compatible API server that provisions managed services in the Microsoft Azure public cloud) and OpenShift’s Service Catalog.

Here’s how to reproduce the demo.
