This example demonstrates how to guard remote service invocations using a circuit breaker.

• Log into an OpenShift cluster of your choice: oc login ....
• Select a project in which the services will be deployed: oc project ....

The greeting-service module serves the web interface and communicates with the name-service.

The name-service module provides an endpoint that simulates a working or failing service.

Run the following commands to configure and deploy the applications.

oc apply -f ./greeting-service/.openshiftio/application.yaml
oc new-app --template=thorntail-circuit-breaker-greeting

oc apply -f ./name-service/.openshiftio/application.yaml
oc new-app --template=thorntail-circuit-breaker-name

mvn clean oc:deploy -Popenshift

This is completely self-contained and doesn't require the application to be deployed in advance. Note that this may delete anything and everything in the OpenShift project.

mvn clean verify -Popenshift,openshift-it
