This post describes how to manually integrate Red Hat OpenStack 9 (RHOSP9) Cinder service with multiple pre-existing external Red Hat Ceph Storage 2 (RHCS2) clusters. The final configuration goals are to have Cinder configuration with multiple storage backends and support for creating volumes in either backend. This post will not cover the initial deployment of OpenStack Cinder or the Ceph clusters. Configuration Rational There are multiple scenarios where RHOSP9 Cinder will need to be configure to multiple RHCS2 storage clusters...

Developers have a lot of choices when deciding how to start using OpenShift and Kubernetes locally --- without going through a native OS installation. We all need to have a development environment as close as possible to production (to prevent defects caused by environmental differences), but ideally we need to do this without spending a lot of time to setup and a lot of computational resources (cpu, memory and disk space). This post will present four alternatives to create a...

Inspired by a great blog post by Jakub Scholz on "Scalable AMQP infrastructure using Kubernetes and Apache Qpid", I wanted to write a post about the ongoing effort to build Messaging-as-a-Service at Red Hat. Messaging components such as the Apache Qpid Dispatch Router, ActiveMQ Artemis and Qpidd scales well individually, but scaling a large deployment can become unwieldy. As Scholtz demonstrates, there are a lot of manual setup when creating such a cluster using kubernetes directly. The EnMasse project was...

Red Hat Developers and author N. Harrison Ripps have just released the first pieces of a ten-part series ("That app you love") in which Harrison describes the process of deploying an application using containers into a clustered environment on the cloud. Using the ZRC IRC client as a sample application, Harrison demonstrates each step in the process of containerizing software, dealing with issues like statelessness, security, and robustness that are typically architectural hurdles for most development teams moving to a...

The last 4-5 years have seen the debut of many new software products specifically targeting both infrastructure services and IT automation. The consumerization of IT has caused its architects to take a fresh look at their existing, often times monolithic apps and IT infrastructure and asking: Can we do better? How do I keep IT relevant? How do I keep track of all these VMs and data? How do I scale out my IT environment without a huge budget increase...

UPDATE: Read the new article " How to run systemd in a container" for the latest information. What is the scoop on running systemd in a container? A couple of years ago I wrote an article on Running systemd with a docker-formatted Container. Sadly, two years later if you google docker systemd this is still the article people see --- it's time for an update. This is a follow-up for my last article. docker upstream vs. systemd I have given...

Prior to working at Red Hat, I worked for a software company, building financial software for large institutions. From my experiences I knew that some customers required, or demanded, a very aggressive Service Level Agreement (SLA). If we consider an SLA of 99.999% (generally referred to as “five nines”) then this would allow for a six-second unavailability or downtime over a full week, anything more and penalties would have to be paid. To provide this level of uptime, it is...

We have just completed the deployment of the Red Hat Mobile Application Platform v3.13 to all our actively updated grids. This is mainly a bug-fix and enhancement release with no major new features. Please pay particular attention to the extra notes below on Node.js 0.10.x, Cordova Light and CocoaPods 1.x. Highlights Fixed: Release builds of Forms Apps failing for Android in Build Farm Fixed: Photos saved as drafts are not being displayed in Forms App Fixed: Cordova push template does...

In an earlier article, Debugging Java Applications using the Red Hat Container Development Kit, it was discussed how developer productivity could be improved through the use of remotely debugging containerized Java applications running in OpenShift and the Red Hat Container Development Kit. Not only does remote debugging provide real time insight into the operation and performance of an application, but reduces the cycle time a developer may face as they are working through a solution. Included in the discussion were...

Ansible serves as a great tool for those system administrators who are trying to automate the task of system administration. From automating the task of configuration management to provisioning and managing containers for application deployments, Ansible makes it easy. In this article, we will see how we can use Ansible to provision Vagrant boxes. So, what exactly is a Vagrant box? In simple terms, we can think of a vagrant box as a virtual machine prepackaged with the development tools...

The charter of Open Innovation Labs is to help our customers accelerate application development and realize the latest advancements in software delivery, by providing skills, mentoring, and tools.

You’ve heard of microservices. You’ve heard of OpenShift. You’ve heard of Kubernetes. Actually, you may already have considerable experience with each of these three concepts and tools. But do you know how to combine all of them in order to deploy microservices effectively? If not, this article is for you. Below, I’ll explain how microservices, OpenShift and Kubernetes fit together, and provide an overview of how you can leverage the orchestration tools provided by OpenShift and Kubernetes in order to...

This year’s middleware keynote address at Red Hat Summit talked about microservices, the power of the pipeline, and how developers and devops can work together to release code to production at a much higher rate. The keynote also demonstrated how releases can be shipped so you can switch from the existing deployment to a new deployment (blue/green deployments), and demonstrated how to roll out a canary deployment to a subset of users to test out new features. (If the canary...
