What is the purpose of oc new-app, and how does it help speed up application creation in OpenShift?

• A. oc new-app compiles code and builds a Docker image automatically.
• B. oc new-app creates a new application by installing and wiring resources based on a source repository, image, and templates; speed up creation by generating Deployment, Service, Route, and BuildConfig from templates.
• C. oc new-app provisions only a single Deployment without related services.
• D. oc new-app removes existing resources and cleans the project.

Answer: (B)

oc new-app is about bootstrapping an application by automatically creating and wiring the OpenShift resources you need, based on a source repo, an image, or a template. When you point it to a git repository or a builder image, it sets up the build configuration and image stream, then creates the deployment (or deployment config), a service to expose the app internally, and a route to expose it externally. This one-command approach speeds things up by turning templates or build logic into ready-to-run objects in your project, so you don’t have to create each resource individually. The actual code compilation happens during the OpenShift build process driven by the BuildConfig; oc new-app itself is just scaffolding and wiring.
