Which command creates a template from the file template.json?

• A. oc new-app -f template.json
• B. oc apply -f template.json
• C. oc create -f template.json
• D. oc create template template.json

Answer: (C)

Templates are stored in OpenShift as resources defined in a manifest. To register such a resource in the cluster, you create it from the file that describes it. The command oc create -f template.json reads the file and creates the Template object as declared, making it available for users to instantiate. This is the straightforward way to add a new Template to the cluster.

Other commands don’t directly register a Template resource in the same way. Using the first option would invoke an application-building flow and isn’t intended for creating a Template object itself. The second option could apply changes to existing resources and, while it can create in some cases, the common, explicit approach for adding a new Template is oc create -f. The final option isn’t valid syntax for OpenShift CLI.
