An application is developed based on microservices. The application must be installed on a pod in a separate cluster. Which command must be used to deploy the application?

`kubectl get nodes` is used to list the nodes in the cluster and their status, not to deploy an application.

`kubectl run deployments` is an incomplete and incorrect command; `deployments` is a resource type, but `kubectl run` requires an image and a name to create an instance.

The `kubectl run` command is used to create and run a specific container or deployment in a Kubernetes cluster. The provided command `kubectl run kubernetes-deployment --image=gcr.io/kubertfetes-deployment:v1 --port=8080` instructs Kubernetes to create a deployment named `kubernetes-deployment`, using the specified Docker image and exposing port 8080, which directly deploys the application as a pod (or set of pods via a Deployment object).

`kubectl version` displays the client and server versions of Kubernetes, which is for informational purposes, not for deploying applications.
