Quickstart requires Java 8 or Java 11 (`fuse-java-openshift-jdk11-rhel8` image is used to build in Java 11). 28 | 29 | == Deployment options 30 | 31 | You can run this quickstart in the following modes: 32 | 33 | * Kubernetese / Single-node OpenShift cluster 34 | * Standalone on your machine 35 | 36 | The most effective way to run this quickstart is to deploy and run the project on OpenShift. 37 | 38 | For more details about running this quickstart on a single-node OpenShift cluster, CI/CD deployments, as well as the rest of the runtime, see the link:http://appdev.openshift.io/docs/spring-boot-runtime.html[Spring Boot Runtime Guide]. 39 | 40 | == Running the Quickstart on a single-node Kubernetes/OpenShift cluster 41 | 42 | IMPORTANT: You need to run this example on Container Development Kit 3.3 or OpenShift 3.7. 43 | Both of these products have suitable Fuse images pre-installed. 44 | If you run it in an environment where those images are not preinstalled follow the steps described in <>. 45 | 46 | A single-node Kubernetes/OpenShift cluster provides you with access to a cloud environment that is similar to a production environment. 47 | 48 | If you have a single-node Kubernetes/OpenShift cluster, such as Minishift or the Red Hat Container Development Kit, link:http://appdev.openshift.io/docs/minishift-installation.html[installed and running], you can deploy your quickstart there. 49 | 50 | 51 | .
