Failed to download OpenAPI error with Kubernetes deployment - docker

Question

I'm learning Kubernetes and I've just installed minikube on my mac.
I have a docker image that I'd like to deploy. I created a deployment yaml file which looks like this:
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: sonarqube
spec:
template:
metadata:
labels:
app: sonarqube
spec:
containers:
- image: docker-sonarqube-developer:latest
args:
- -Dsonar.web.context=/
name: sonarqube
env:
- name: SONARQUBE_JDBC_USERNAME
value: sonarqube
- name: SONARQUBE_JDBC_PASSWORD
value: sonarqube
ports:
- containerPort: 9000
name: sonarqube
I am trying to deploy my docker image on minikube with the following command:
kubectl create -f deployment.yaml
But I'm getting an error and I'm not sure what's going on.
W0628 09:18:45.550812 64359 factory_object_mapping.go:423] Failed to download OpenAPI (the server could not find the requested resource), falling back to swagger
error: error validating "k8s/deployment.yaml": error validating data: the server could not find the requested resource; if you choose to ignore these errors, turn validation off with --validate=false
Minikube is running and I can access the dashboard.
❯ kubectl get nodes
NAME STATUS ROLES AGE VERSION
minikube Ready master 17h v1.15.0
The docker image is available locally
❯ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED
6fcfdad92d16 docker-sonarqube-developer "./bin/run.sh" 16 hours
Any idea what's wrong?
Thanks!

First Check the kubectl version
Check whether the Minor for both client and server version are same
$Kubectl version
Client Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.20.2",
Server Version: version.Info{Major:"1", Minor:"20", GitVersion:"v1.20.0",
If not,then follow the below steps-
$curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/darwin/amd64/kubectl
$chmod +x ./kubectl
$sudo mv ./kubectl /usr/local/bin/kubectl
Now check the version again
$kubectl version
Client Version: version.Info{Major:"1", Minor:"20", GitVersion:"v1.20.2",
Server Version: version.Info{Major:"1", Minor:"20", GitVersion:"v1.20.0",
$kubectl create -f deployment.yaml
