 TIP: If you want to test your application immediately then set the `quarkus.openshift.route.expose` config property to `true` to <<exposing_routes,expose the service automatically>>, e.g. add `-Dquarkus.openshift.route.expose=true` to the command above.
 
+[#re-deploy-with-service-binding]
+NOTE: When using `DeploymentConfig` and https://quarkus.io/guides/deploying-to-kubernetes#service_binding[Service Binding], re-deploying might remove the configuration added by OpenShift to allow service discovery. A new container image build will trigger a refresh of the Quarkus app in OpenShift: `-Dquarkus.container-image.build=true` which might be enough in most situations. If you need to update the OpenShift resources, you need to delete the binding first to create it again after new deployment.

 This command will build your application locally, then trigger a container image build and finally apply the generated OpenShift resources automatically.
 The generated resources use OpenShift's `DeploymentConfig` that is configured to automatically trigger a redeployment when a change in the `ImageStream` is noticed.
 In other words, any container image build after the initial deployment will automatically trigger redeployment, without the need to delete, update or re-apply the generated resources.
