run kube-inject over a single file that contains multiple Service,
ConfigMap, Deployment, etc. definitions for a complex application. When in
doubt re-run istioctl kube-inject on deployments to get the most up-to-date changes.

It's best to do kube-inject when the resource is initially created.
`,
		Example: `  # Update resources on the fly before applying.
  kubectl apply -f <(istioctl kube-inject -f <resource.yaml>)
