Code convention: use nouns instead of verbs whenever possible. Reasoning: One can apply just about anything to Kubernetes via this: deployment, load balancer, RBAC policy, a custom CRD resource, etc. Upstream those are called resources: You give `kubectl apply` one or more manifests and it will create the corresponding resources.
