This is a Vert.x microservice that represents catalog information in a retail store. It uses the Fabric8 Maven Plugin to deploy to OpenShift.
Calls to the database are wrapped in a circuit breaker, providing fast fail in case of issues with the database.
The configuration of the application is provided by a Openshift ConfigMap.
You'll need to have access to an OpenShift cluster and the oc command line interface.
- Login to OpenShift and create a new project
oc login
oc new-project demo
- Create a ConfigMap from the
app-config.yamlfile in theetcfolder:
oc create configmap app-config --from-file=etc/app-config.yaml
- Add the view role to the default service account. The application uses the Kubernetes API to retrieve the ConfigMap, which requires view access.
oc policy add-role-to-user view -z default
- Deploy the MongoDB database using the template in the
ocpfolder
oc process -f ocp/coolstore-catalog-mongodb-persistent.yaml -p CATALOG_DB_USERNAME=mongo -p CATALOG_DB_PASSWORD=mongo | oc create -f -
- Use the Fabric8 Maven Plugin to launch the S2I process on the OpenShift Online machine & start the pod.
mvn clean fabric8:deploy -Popenshift -DskipTests
This will build and deploy the microservice.
