We know that containers in Openshift or Kubernetes don't persist data. Every time we start an application, it is started in a new container with an immutable Docker image. Hence, any persisted data in the file systems is lost when the container stops. Hence if an application or container is rebuilt or restarted than we can't view previous logs or if we are using containers with mysql or any other database then schema, tables, and all data will be lost...

The release of OpenShift Container Platform 3.6 brings support for vsphere cloud provider. This provides vsphere VMDK dynamic provisioning for persistent volumes for container workloads. The storage presented to vsphere virtual machines as a VMDK has ReadWriteOnce access mode. In the OCP 3.6 on vSphere reference architecture, much of this process is automated and can be implemented easily. Virtual Machine Disks or VMDKs exists in virtual machines. Configuring the OCP cluster for vsphere cloud provider support requires: Master Node Configuration...

Modern applications development demands optimized tools and services. Applications must integrate with different systems and share data. Organizations must be able to immediately respond to changing conditions. JBoss Middleware drives enterprise application innovation every day to deliver the best projects and products. Whether you are an experienced enterprise application developer or just getting started, JBoss: Developer’s Guide provides you with the best time to value guide for enterprise application delivery with the JBoss brand, using hands-on coding and lab exercises...

Distributed Architectures are a lot like neural networks; all services that talk to each other need to share the I/O in and in a way that they can synchronize that information on the fly. The way the brain does is that each neuron that communicates with another has the other neuron fire back a neurotransmitter to synchronize and improve that communication in the future thus creating a pattern. While this behavior is almost identical to what is known as a...

Red Hat JBoss Fuse is an open source, lightweight and modular integration platform that allows you to connect services and systems across your entire application portfolio. If you’re familiar with Fuse, you’re probably familiar with the Fuse Tooling that comes with Red Hat JBoss Developer Studio. If you read carefully the last announcement for Red Hat Development Tools, you may have noticed that Fuse Tooling and Fuse runtimes are now part of Development Suite. That new feature might seem like...

Besides testing, Java code coverage can be a very effective debugging tool as it helps you see which code is ran. EclEmma is a great Java code coverage tool that has an Eclipse plugin. It's very simple and intuitive and has all you would expect from a code coverage tool. With it, you can: See code coverage for a java application that you've run (and potentially merge multiple run instances) See code coverage for jUnit tests and maven tests See...

This year JavaOne 2017 is being held at the Moscone Center in San Francisco, CA during October 1-5, I will be a holding a session for reactive programming covering The Reactive Landscape. In this session, I'm going to explain what does "reactive" mean. There are many reactive things today, are all these "things" related? In addition, many concepts are associated with reactive such as messaging, elasticity, streams back-pressure and RX. This presentation explores the reactive landscape and explains the different...

It has been a year since I posted the announcement about the availability of the Java Language Support for Visual Studio Code. During this past year, we made 10 releases, added various features, fixed many bugs but more importantly, we have constantly grown our user base and finally reached and passed a million downloads on the Visual Studio Marketplace. Fred Bricon, Snjezana Peco and I, as the core team have worked on the Java Language Server and the Visual Studio...

It has long been recognized that unconstrained growth of memory usage constitutes a potential denial of service vulnerability. Qualys has shown that such unconstrained growth can be combined with other vulnerabilities and exploited in ways that are more serious. Typically, the heap and stack of a process start at opposite ends of the unused address space and grow towards each other. This maximizes the flexibility to grow the regions over the course of execution of the program without apriori knowing...

Using agile integration for IoT initiatives enables standards-based solutions that can be quickly built and deployed at scale

Introduction I'm working on the upstream fabric8-wit project of openshift.io. In this Go project, we embrace testing as best as we can in order to deliver a stable component. Testing acts as our safety net to allow for fast-paced feature development. This blog post is about our recent change in our testing strategy. It is not as boring as it might sound at first. ;-) Problem description We've changed out the data-model quite a lot and it took us a...

Build Microservices by coupling JBoss Undertow with the most popular Java EE frameworks like CDI, JPA...

Typical CI process (source: www.pepgotesting.com) Continuous Integration (CI) is a phase in the software development cycle where code from different team members or different features are integrated together. This usually involves merging code (integration), building the application and carrying out basic tests all within an ephemeral environment. In the past, the code was integrated at an “integration phase” of the software development life cycle. This phase came after different teams would have spent weeks, months or even years working in...

Several Red Hat engineers attended the JTC1/SC22/WG21 C++ Standards Committee meetings in July 2017. This post focuses on the sessions of SG1, the study group on parallelism and concurrency. We discussed several synchronization-related proposals, improvements for futures, and, of course, executors. Also, I proposed a few steps that the SG1 community could take to get more efficient in how it conducts its work, which are all inspired by how successful open source projects work. Most of the proposals we discussed...

Red Hat JBoss Fuse provides an open source, lightweight, modular platform that enables you to connect a variety of services and systems across your application environment. And, included with Red Hat JBoss Developer Studio, is the Fuse Tooling that helps you take advantage of that platform. The route editor initially focused on the parts of the Camel configuration inside the route or Camel context element, but in version 8.0.0, we began adding support for global elements such as data formats...

OpenShift Container Platform (OCP) offers many different types of persistent storage. Persistent storage ensures that data should be insistent between builds and container migrations. When choosing a persistent storage backend to ensure that the backend supports the scaling, speed, dynamic provisioning, RWX/RWO support and redundancy that the project requires. Container-Ready Storage (CRS), or native Gluster for OCP, is defined by the concept of persistent volumes, which are OCP created objects that allow storage to be defined and then used by...

I’m extremely pleased to announce the latest releases of our Red Hat developer tools, available on multiple platforms.

(Part 3)The GNU Toolchain is a collection of programming tools produced by the GNU Project. The tools are often packaged together due to their common use for developing software applications, operating systems, and low-level software for embedded systems.

Note: This is an updated version of a post I wrote for my private blog years ago. While working on the REST API of RHQ a long time ago, I had started writing some integration tests against it. Doing this via pure HTTP calls is very tedious and brittle. So, I was looking for a testing framework to help me and found one that I used for some time. I tried to enhance it a bit to better suit my...

EDI, or Electronic Data Interchange, has always been a challenging domain to support for organizations. As EDI standards cover a large range of industries, from supply chain to medical to financial services (FSI), the standards rapidly evolve and change over time, thus requiring constant maintenance. The sheer cost of maintaining standards is high, not only for organizations but also for EDI software vendors who struggle to keep up. The expensive fees paid to standards organizations and rapidly evolving releases are...
