Which command requests a new build for an application?

• A. oc start-build <application-name>
• B. oc start-build application-name
• C. oc new-build <application-name>
• D. oc trigger-build <application-name>

Answer: (A)

To request a new build for an application, you trigger the BuildConfig with the start-build command and specify the BuildConfig (application) name. BuildConfigs define how to build the app; starting a build tells OpenShift to run that process again using the current source and configuration. The other options serve different purposes: creating a new BuildConfig with new-build, or using a non-existent trigger-build command. So the correct approach is to run the build trigger command followed by the application’s BuildConfig name.
