Which command creates a deployment config using a shared image stream named shared/myis?

Which command creates a deployment config using a shared image stream named shared/myis?

• A. oc new-app --as-deployment-config -i shared/myis
• B. oc new-app -i shared/myis --as-deployment-config
• C. oc new-app --name myis --image shared/myis
• D. oc create deploymentconfig myis --image shared/myis

Answer: (A)

OpenShift uses the new-app flow to generate resources from an image source, and the flag that forces the result to be a DeploymentConfig ensures that the created object runs as a DeploymentConfig rather than a Deployment. By pointing to a shared image stream with the image spec shared/myis and explicitly requesting a DeploymentConfig, the command builds a DeploymentConfig whose pod template uses the image from that shared image stream. This combination is the direct, unambiguous way to create a DeploymentConfig from a shared image stream in one step.
