CI/CD

One of the core drivers behind modern application architecture, development and delivery methodologies like micro-services, agile and CI/CD is the ability to automatically test any software artifact, from application code to server configuration. Automated testing gives us the reliable, repeatable, assurance that our software meets the required quality with respect to aspects like functionality, performance, and scalability and is ready to be deployed in production. Why should testing of a business-process defined in BPMN2, a deployable software artifact, be any...

Following my introduction blog about why microservices should be event-driven, I’d like to take another few steps and blog about it. (Hopefully I saw you at jBCNconf and Red Hat Summit in San Francisco, where I spoke about some of these topics). Follow me on twitter @christianposta for updates on this project. In this article we discuss the first parts of carving up a monolith. The monolith I’m exploring in depth for these articles will be from the Ticket Monster...

I'm sure you have heard and read a lot about microservices in the recent past and how they are here to defend our end users from the horrible monolith. Breaking an application up into many components is a great start, but to take your organization to the next level requires a platform focused on integrating microservices into your continuous improvement process. Red Hat's James Rawlings & James Strachan led us through achieving our new goal of continuous delivery with containerized...

The Problem Several months back, our emerging Developer Programs engineering team assembled during the last breaths of Brno's Czech winter and dedicated a full day towards a deceptively complex task: Be a user. Assemble in groups and, using a technology stack of your choosing, conceive of and create an application to be presented to the full team in 6 hours. Keep in mind that I hold my colleagues in extremely high regard; they're capable, creative, and experienced. Surely churning out...

We are pleased to announce that Rachel Laycock, Head of Technology for North America at ThoughtWorks, will be joining us at DevNation 2016 as a general session speaker. With her background in Agile, Continuous Delivery, and strategy, Rachel is uniquely qualified to explain why CD is more than simply using new tools. This is certainly a relevant topic for everyone - should be fun! Welcome, Rachel! RACHEL'S ABSTRACT: There are several factors to adopting the practices of Continuous Delivery. Most...

Jenkins is great, and it has done a lot to make our lives easier. It seems like not so long ago when the idea of continuous integration tools was a daunting task. Jenkins came to the rescue, and I (and many others) use it a lot... A LOT. Given that my day to day work is in consulting, I'm constantly working in different development environments with different technologies - and a common thread among all those environments is Jenkins. It...

In today's fast paced world of business, delivering quickly is a top priority. Doing so is difficult, however, if you lack confidence in your codebase or rely on error prone deployment processes. Continuous integration enables development teams to automatically run test cases prior to merging code into a stable branch, while continuous deployment leverages automation to provide more reliable, faster deployments of that code. Red Hat Mobile Application Platform supports an agile approach to developing, integrating, and deploying enterprise mobile...

Rebase-helper is a tool that helps Linux package maintainers update their to the latest upstream version. New maintainers and experts alike will find value in the convenience this tool can offer. Rebase-helper applies patches, packages, and reports differences between the patched and un-patched versions.In summary, it automates some of the manual tasks usually performed by package maintainers when a new upstream version of that package is released. This article will explain how to get started using rebase-helper, and also demonstrate...

Automated testing is one of the hardest, but also the most important thing to get right when doing Continuous Delivery or DevOps. Recently Aslak Knutsen and I hosted a webinar with the title "Continuous Development with Automated Testing". The webinar had quite a few viewers (and maybe that was one of the reasons that the demo in the webinar didn't exactly go as planned.) Aslak did a great job trying to talk through a demo that played at 1/3 of...

So you finally surrendered to containers and discovered that they solve a lot of problems and have a lot of advantages: First: Containers are immutable - The OS, library versions, configurations, folders, and application are all wrapped inside the container. You guarantee that the same image that was tested in QA will reach the production environment with the same behaviour. Second: Containers are lightweight - The memory footprint of a container is small. Instead of hundreds or thousands of MBs...

Join us on Thursday, January 28, 2016 for a free Taste of Red Hat Training webinar: Integrating continuous integration with OpenShift Enterprise. During this one-hour webinar Red Hat curriculum manager, Ricardo Jun, will teach you how to implement continuous integration in a project with OpenShift Enterprise. You will also learn how using container images built from application source code can improve efficiency, patch-ability, and speed. This webinar uses content from our OpenShift Enterprise Development (DO290) course. Register for the webinar...

OpenShift Enterprise by Red Hat was designed to be application architecture agnostic. In addition to running traditional stateful and/or legacy-type workloads, OpenShift Enterprise seamlessly provides support for modern, stateless Twelve-Factor applications. This document provides a guide on how to optimize the architecture and deployment of your Twelve-Factor applications on OpenShift Enterprise. Note: The Twelve-Factor app is a methodology for building apps in modern cloud environments. Read more at http://12factor.net/. Factor Relationship Codebase One codebase tracked in revision control, many deploys...

Andrew Block of Red Hat will be speaking on this topic at DevOps Enterprise on 21 October - below is a primer from him on what he'll cover: Although the DevOps movement clearly and correctly centers around culture and the processes that guide or derail our success, the root of this shift often gets overlooked in favor of the symptoms. Sure, we all want our teams better aligned and more consistent, our processes streamlined and automated, our release cycles as...

So here's are deal: We've created what we're calling "PaaS-Containers" in our IT production environment. It consists of core technologies like RHEL Atomic Host, Kubernetes, and Docker along with supporting CI/CD components like Jenkins together as part of an offering that supports the end-to-end automated deployments of applications from a code-commit event through automated testing and roll-out through multiple environments (dev, QA, stage, prod). Oh, did I mention that it's also integrated with our enterprise logging and monitoring as well...

"DevOps". If you're like me, you may be suffering a bit of buzzword fatigue, especially relating to how this word is used (or misused) within the IT community. But for those of us who have been a part of the community for a while, it holds deeper meaning than the oft-repeated platitude of "Software Developers and Sysadmins working together, riding unicorns over rainbows". Okay, while I may have gotten slightly carried away, you get the point. What is DevOps to...
