As an application developer, you can deploy a Quarkus application on Red Hat OpenShift Container Platform using Apache Maven and the quarkus-openshift extension in a single build command or you can use the traditional source-to-image (S2I) method. The resulting image from either method is fully supported. See the Development Support Scope of Coverage page for the build process and tools that are covered under development support.

You can deploy a Quarkus application compiled to a native executable using OpenShift Serverless Knative Serving and scale services up or down. Scaling down services can improve memory capabilities.
