K8s Error from server (NotFound): deployments.apps "nginx" not found

Problem

Coursera Google Cloud Fundamentals: Getting Started with Kubernetes Engine has the instructions to run and expose the pod. The demo video shows it is working.

enter image description here However, it causes the error in my execution. How to fix?

kubectl run nginx --image=nginx:1.10.0
kubectl expose deployment nginx --type LoadBalancer --port 80 
---
Error from server (NotFound): deployments.apps "nginx" not found

Environment

GCP k8s.

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"22", GitVersion:"v1.22.1", GitCommit:"632ed300f2c34f6d6d15ca4cef3d3c7073412212", GitTreeState:"clean", BuildDate:"2021-08-19T15:45:37Z", GoVersion:"go1.16.7", Compiler:"gc", Platform:"linux/amd64"}

Cause

kubectl run does not create deployment.

'Error from server (NotFound): deployments.extensions "nginx" not found' when exposing NodePort #31

Did you create a pod with "kubectl run"? If yes, that doesn't create a deployment with (at least) kubectl v1.18.2, so instead use "kubectl create deployment nginx --image=nginx:1.10.0"

Fix

Create a deployment as in Creating and exploring an nginx deployment from a YAML or run kubectl create deployment ....

$ kubectl create deployment nginx --image=nginx:1.12.0
deployment.apps/nginx created

$ kubectl expose deployment nginx --type LoadBalancer --port 80
service/nginx exposed

$ kubectl get services
NAME         TYPE           CLUSTER-IP     EXTERNAL-IP      PORT(S)        AGE
kubernetes   ClusterIP      10.83.240.1    <none>           443/TCP        44m
nginx        LoadBalancer   10.83.246.84   35.225.127.227   80:30825/TCP   60s
