Creating a simple MicroProfile-based microservice and deploying it to OpenShift Container Platform Eclipse MicroProfile is an open source specification for Enterprise Java microservices. It is a community of individuals, vendors, and organizations collaborating and working on innovative microservices patterns for Enterprise Java within the context of modern development, architectures, and underlying infrastructures, e.g. health checks, fault tolerance, metrics, and security propagation within a cloud environment. Its first release was based on 3 Java EE JSRs/libraries/APIs, but this does not necessarily...

"I used WildFly Swarm to shrink my app from 45 megabytes to only 2243 bytes." I was recently playing around with various techniques for packaging Java microservices and running on OpenShift using various runtimes and frameworks to illustrate their differences (WildFly Swarm vs. WildFly, Spring Boot vs. the world, etc). Around the same time as I was doing this an internal email list thread ignited discussing some of the differences and using terms like Uber JARs, Thin WARs, Skinny WARs...

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...

What is it about? OpenShift has seen a lot of traction with the release of its third version based on Kubernetes a couple of years ago. More and more companies after a thorough evaluation of OpenShift Container Platform (OCP) have built an on-premise or in the cloud PaaS. With the next step, they have started to run their applications on OCP. One of the important aspects of running applications in production is the capacity of quickly restoring services to the...

Background I’ve been working with the CTO of an online video game company to develop a container architecture for his business. The goal is to simplify the deployment of new applications as well as make it easier to go back and change the code on older applications. The desired state is environmental parity across the infrastructure -- this will simplify the assignment of work on different applications to different developers. From developer laptops to production servers, the code will just...

Microservices is probably one of the most popular buzz words among my fellow developer friends, and I do like the concept of being flexible, agile and having simply having more choices. But as a person that worked in the software integration space for years, I started to see some resemblance of the old ESB days. Looking at the problem from ten thousand feet up. A decade ago, we had to come up with a better way of organizing the spaghetti...

Hi, Everybody! Today I want to introduce you to some features of OpenShift 3.6 while giving you the chance to have a hands-on experience with the Release Candidate. First of all: It's a Release Candidate and the features I'll show you are marked as Tech Preview, so use them for testing purpose ONLY! We cannot use Minishift just because there is no Minishift updated yet. Anyway, I'll show how could use its base iso-image. I don't want to use 'oc...

I've been using containers for nearly 3 years, initially working in the Technical Support team helping customers solve problems in their applications and giving advice about best practices to run containers. Today I work on a team where we develop containers to use in our OpenShift environment, and because of my Technical Support background, my troubleshooting skills helped me in this task. I run containers for most of my tasks and it makes my life easier. I can run any...

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...

I’m assuming you’ve already tried to run some example of a multi-container application. Let’s say we have an application composed of the following: Web service Database Key-value store Worker Let’s focus on the database now. Container images for databases usually come with an easy way to configure them via environment variables. The great thing about this approach is how easy to use it is, e.g. let’s take our RHSCL PostgreSQL 9.5 container image. If you try to run it just...

With a major release, you would usually expect major modifications in the core of the framework. But this time, the migration is not too complicated. Not only because of the migration tool provided to make a smooth transition from Framework 7 to Framework 8, but also because of the similarity in many of the components’ APIs. A good upgrade strategy is needed though, and I summarized them under the following headlines: Upgrade dependencies in the POM file Run Maven goal...

Getting up and running with local development for Red Hat Mobile Application requires that you run MongoDB and Redis locally. Doing so isn’t particularly difficult if you follow online guides, but it would be much more straightforward if you could just get these pieces of software up and running in a single command and not need to worry about versioning, creating data directories, setting permissions, and compiling some things such as Redis from source. It would be even better if...

In a previous blog post, we explained how to deploy an existing JBoss BRMS/Drools rules project onto an OpenShift DecisionServer. We created a decision/business-rules microservice on OpenShift Container Platform that was implemented by a BRMS application. The polyglot nature of a microservice architecture allowed us to use the best implementation (a rules engine) for this given functionality (business rules execution) in our architecture. The project we used was an existing rules project that was available on GitHub. We did however...

In this small screencast we'll show you how to get started with OpenShift using JBoss Tools. We'll show you how to create an new OpenShift application and import it to your Eclipse workspace. We'll then show you how to change the starter-application in your workspace, and push those changes to OpenShift.
