In the microservices landscape, the API provides an essential form of communication between components. To allow secure communication between microservices components, as well as third-party applications, it's important to be able to consume API keys and other sensitive data in a manner that doesn't place the data at risk. Secret objects are specifically designed to hold sensitive information, and OpenShift makes exposing this information to the applications that need it easy. In this post, I'll demonstrate securely consuming API keys...

GDB relies on libcc1's GCC and GDB plugins to implement the " compile code" feature, now extended to support the C++ language. The Compile and Execute machinery enables GDB users to compile and execute code snippets within the context of an existing process. This allows users to perform inspection and modification of the program state using the target language well beyond the feature set historically exposed by symbolic debuggers. Almost anything that can be expressed in C, and now also...

One of our most popular Red Hat JBoss BRMS demo's, and one that has been available for quite some time, is the CoolStore demo. The CoolStore demo shows how business rules can be used to calculate values like promotional and shipping discounts in a shopping-cart. It furthermore illustrates concepts like ruleflow-groups and dynamic rule updates using KieScanner. Rules and micro-services: the JBoss BRMS Decision Server One of the more interesting features we've recently released in the Red Hat JBoss BRMS...

Last June, Eclipse IDE had a great release, named Neon. It features, among many other less visible but still quite useful improvements, many new functionalities for everyone. If you did not migrate yet and are still using an older Eclipse version, just move to Neon right now, it’s worth it! For this Neon release, Red Hat managed to increase its contributions to the Eclipse IDE. The 2 main teams doing Eclipse IDE development (to package Eclipse IDE as .rpm for...

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...

If you want to start from the beginning, jump back and check out Part 1: Making a connection. In our last post, we met my ZNC container, good ol’ znc-cluster-app - but don’t fret about ZNC because we’re really talking about That App You Love - whatever it happens...

Thermostat is Red Hat's Monitoring and management tool for Java Deployments, allowing users to measure and monitor a host of different performance aspects of their Java applications. Available metrics range from raw CPU and memory usage to operation of the Garbage Collector and Compiler through to thread activity and method call/heap profiles. Thermostat provides a GUI view of activity of local and distributed JVMs in real time and it also backs up all the metrics it obtains to a persistent...

I am going to show you how I took an everyday, off-the-shelf application and turned it into a cluster-ready juggernaut of persistent usefulness. Along the way, I’ll share the pitfalls that I hit in getting this all working so that you can chuckle at my misfortune and avoid having to make the same mistakes yourself. This series will run every Tuesday and Thursday until we've accomplished our goals, so stay tuned in, subscribe, and thanks for reading! Meet “That App...

Java language server is an implementation of the language server protocol for Java. If you recall, language server protocol provides a common way for editors and IDEs to integrate with language smartness providers. By design, all of the language tooling magic happens on the Java language server, and can provide same level of smartness to tools that support the protocol. In fact, we are working with communities such as Eclipse Che to make this server available for their tools. As...

Red Hat Enterprise Linux (RHEL) is not Ubuntu. Out of the box, it seems the default packages installed for developers are somewhat limited. To provide exceptional long-term stability, Red Hat takes a different approach to default packages and software repositories (repos). Development tools aren't installed unless specifically selected. The repos that are initially enabled only contain packages that Red Hat supports over the long term lifecycle of RHEL. Because RHEL’s default repos don’t have as large a selection of development...

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...

Being able to edit your C# (or F# for that matter) code on your Linux VM from Visual Studio in Windows is pretty great. As a Windows developer, you're able to work in an environment you know and trust while still being able to experiment -- and hopefully produce production code -- in Linux, where you may not be quite up to speed. Yet. Visual Studio, that familiar, productive and helpful IDE, is at your fingertips even though your code...

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...

Running .NET on Linux, using the Red Hat Container Development Kit (CDK), means your Linux VM is running "headless" -- you don't have a desktop UI. You have a command line, and that's it. Note: If you aren't running .NET on Linux, hop over to the Red Hat Developer's web page and download the CDK to get started. Red Hat Enterprise Linux's built-in editor, VIM, which is launched by the command vi, is not a full-featured development environment. Not even...

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...
