Which command creates an app named myjava from template dev/lampstack in namespace dev with PORT=8080?

• A. oc new-app --template dev/lampstack -p PORT=8080 --name myjava --namespace dev
• B. oc new-app --template dev/lampstack -p PORT=8080 --name myjava -n dev
• C. oc new-app --template dev/lampstack -p PORT=8080 --name myjava
• D. oc new-app --template dev/lampstack -p PORT=8080 --name myjava -n dev

Answer: (D)

The command is using a template to create an app, while explicitly setting the port, the application name, and the target namespace. It pulls the template dev/lampstack, passes the parameter PORT=8080 so the app will use that port, names the resulting application myjava, and places the resources into the dev namespace with the short form -n for namespace. This combination directly satisfies “create an app named myjava from template dev/lampstack in namespace dev with PORT=8080.” The long form for the namespace (--namespace dev) is also valid in other contexts, but the version using -n dev is a common, concise way to specify the target project in OpenShift.
