Bringing Coolstore Microservices to the Service Mesh: Part 2–Manual Injection

Coolstore+Istio Logo

In the first part of this series we explored the Istio project and how Red Hat is committed to and actively involved in the project and working to integrate it into Kubernetes and OpenShift to bring the benefits of a service mesh to our customers and the wider communities involved. If you want to play with Istio, check out the service mesh tutorials on learn.openshift.com. If you want to install it, follow the Istio Kubernetes quickstart instructions and install it on OpenShift 3.7 or later. Also don’t miss Don Schenck’s series of blogs on Istio technology in general to learn more about it and what Red Hat is doing in this space.

In this post, we will deploy the existing Coolstore microservices demo as a service mesh and start to demonstrate the tangible value you can get out of the system without any major rewrite or rearchitecture of the existing app. We’ll also improve our project along the way to adhere to Istio (and general microservice) best practices. In the real world, your applications and developers often make bad assumptions or fail to implement best practices, so with this information you can learn something about your own projects. For Coolstore, many of these workarounds will eventually find their way into the source code of the demo.

Enabling Byteman Script with Red Hat JBoss Fuse and AMQ – Part 2

By Chandra Shekhar Pandey

In my previous article, Enabling Byteman Script with Red Hat JBoss Fuse and AMQ – Part 1, we found a basic use-case for Byteman scripts with Red Hat JBoss Fuse or Red Hat JBoss AMQ. However, the log file was generated separately and only limited operations were possible. In this article I will show you how to use a Java helper class. By using Java, we get advanced operations to view or modify the content. Also, using java.util.logging allows us to log the statements to fuse.log, avoiding the creation of any other log file.

Which Camel DSL to Choose and Why?

By Bilgin Ibryam

Apache Camel is a powerful integration library that provides mainly three things: lot’s of integration connectors + implementation of multiple integration patterns + a higher-level Domain Specific Language (DSL) abstraction to glue all together nicely. While the connectors and pattern choices are use case and feature driven and easy to make, choosing which Camel DSL to use might be a little hard to reason about. I hope this article will help to guide you in your first Camel journey.
