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

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.

Summary

Today Red Hat is making Node.js generally available to Red Hat customers through a subscription to Red Hat OpenShift Application Runtimes (RHOAR). RHOAR provides application developers with a variety of application runtimes running on the OpenShift Container Platform.

Node.js is based on the V8 JavaScript engine and allows you to write server-side JavaScript applications. Node.js joins the existing set of supported runtimes and offers developers an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Develop Cloud-native Applications with MicroProfile (Config & Health Check) and OpenShift

Develop Cloud-native Applications with MicroProfile (Config & Health Check) and OpenShift

A previous article described the specifications in the Eclipse MicroProfile 1.2 release and the benefits for Java-based cloud-native applications. This article shows how software developers writing Java-based microservices can leverage those specifications to take advantage of the management capabilities provided by Red Hat OpenShift.
