I have created a Kubernetes cluster on GCP and trying to pull the image from docker hub and run it in a container. I am using the following Kubectl command.

  sutterhome1976@cloudshell:~ (cohesive-armor-310718)$ Kubectl create deployment hello-world-rest-api --image=in28min/hello-world-rest-api:0.0.1.RELEASE

What does that error means? the docker image does very much exist.

   -bash: Kubectl: command not found

I made sure the image exists on docker hub at https://hub.docker.com/r/in28min/hello-world-rest-api/tags?page=1&ordering=last_updated
