CI/CD

Over the last couple of weeks, I've been working on some Red Hat JBoss BPM Suite workshop material. One part of the workshop is a four-hour lab that guides the attendees through the development of JBoss BPM Suite 6.x processes, rules and applications (note that this workshop is available to our customers, please contact your Red Hat account manager or local Red Hat sales representative for more information), but I'm going to be sharing part of the story with you...

In the process of writing my posts ( #1 and #2) on . NET Core and RHEL, it was made clear to me by several friends that I had neglected to use the de facto standard for continuous integration on Linux, Jenkins. Always happy to try out new (to me) tools, I settled in for what I was assured would be a simple configuration to test out my previous work in this bastion of automation. What is Jenkins? The first...

If you like pipelines—specifically the kind that facilitate continuous software delivery, not the ones that drain stuff from your kitchen sink—you'll love Jenkins 2.0. Pipelines-as-code are one of the headline features in the latest version of Jenkins. Keep reading for more on pipelines and other cool enhancements in Jenkins 2.0, and how you can take advantage of them. Jenkins 2.0: New Features Outline Released in April, Jenkins 2.0 is the much-updated version of the open source continuous integration and delivery...

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. Some of the challenges I frequently hear from customers are those around Platform as a Service (PaaS) environment provisioning and configuration. This article is first in the series of articles that guide you through installation configuration and usage of the Red Hat OpenShift Container Platform (OCP) on Amazon Web Services (AWS). This...

As far as automated configuration management tools go, Ansible is “the new hotness” on the market. I admit, I am pretty new to Ansible. Until recently, the majority of my configuration management experience has been rooted solely in Puppet. Tack onto that my recent foray back into the world of Red Hat and I have a lot to learn, starting with getting Ansible installed and running on RHEL. There are two ways to install Ansible—via yum, or directly from source...

In this series of articles, I will present several ways to deploy an application on an EAP Domain. The series consists of four parts. Each one will be a standalone article, but the series as a whole will present a range of useful topics for working with JBoss EAP. Part 1: Set up a simple EAP 7.0 Domain (this article). Part 2: Domain deployments through the new EAP 7.0 Management Console Part 3: Introduction to DMR ( Dynamic Model Representation)...

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...

Microservices are standing at the " Peak of Inflated Expectations". It's immeasurable the number of developers and companies that want to bring in this new development paradigm and don't know what challenges they will face. Of course, the challenges and the reality of an Enterprise company that has been producing software for the last 10 or 20 years is totally different from the start-up company that just released its first software some months ago. Before adopting microservices as an architectural...

If you are using JBoss Enterprise Application Platform (EAP) for J2EE development, the CloudBees Jenkins Platform provides an enterprise-class toolchain for an automated CI/CD from development to production. The CloudBees Jenkins Platform now supports integrations with both Red Hat JBoss Enterprise Application Platform (EAP) and Red Hat OpenShift across the software delivery pipeline. This enables developers to build, test and deploy applications, with Jenkins-based continuous delivery pipelines in JBoss via JBoss EAP 7 or JBoss EAP 7 on OpenShift. The...

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...

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...
