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

Question

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.
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

WARNING: version difference between client (1.22) and server (1.20) exceeds the supported minor version skew of +/-1

Answer 1

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
