Four different errors when using kubectl apply command - kubernetes

Question

My docker-compose file is as below:
version: '3'
services:
nginx:
build: .
container_name: nginx
ports:
- '80:80'
And my Dockerfile:
FROM nginx:alpine
I used kompose konvert and it created two files called nginx-deployment.yml and nginx-service.yml with the below contents.
nginx-deployment.yml:
apiVersion: apps/v1
kind: Deployment
metadata:
annotations:
kompose.cmd: kompose convert
kompose.version: 1.22.0 (955b78124)
creationTimestamp: null
labels:
io.kompose.service: nginx
name: nginx
spec:
replicas: 1
selector:
matchLabels:
io.kompose.service: nginx
strategy: {}
template:
metadata:
annotations:
kompose.cmd: kompose convert
kompose.version: 1.22.0 (955b78124)
creationTimestamp: null
labels:
io.kompose.service: nginx
spec:
containers:
- image: nginx:alpine
name: nginx
ports:
- containerPort: 80
resources: {}
restartPolicy: Always
status: {}
And nginx-service.yml:
apiVersion: v1
kind: Service
metadata:
annotations:
kompose.cmd: kompose convert
kompose.version: 1.22.0 (955b78124)
creationTimestamp: null
labels:
io.kompose.service: nginx
name: nginx
spec:
ports:
- name: "80"
port: 80
targetPort: 80
selector:
io.kompose.service: nginx
status:
loadBalancer: {}
My kustomization.yml:
resources:
- nginx-deployment.yml
- nginx-service.yml
All files are in the same path /home.
I run these three commands but for each of them I got a different error:
kubectl apply -f kustomization.yml:
error: error validating "kustomization.yml": error validating data: [apiVersion not set, kind not set]; if you choose to ignore these errors, turn validation off with --validate=false
kubectl apply -k .:
error: accumulating resources: accumulation err='accumulating resources from 'nginx-deployment.yml': evalsymlink failure on '/home/nginx-deployment.yml' : lstat /home/nginx-deployment.yml: no such file or directory': evalsymlink failure on '/home/nginx-deployment.yml' : lstat /home/nginx-deployment.yml: no such file or directory
kubectl apply -f kustomization.yml --validate=false:
error: unable to decode "kustomization.yml": Object 'Kind' is missing in '{"resources":["nginx-deployment.yml","nginx-service.yml"]}'
kubectl apply -k . --validate=false:
error: accumulating resources: accumulation err='accumulating resources from 'nginx-deployment.yml': evalsymlink failure on '/home/nginx-deployment.yml' : lstat /home/nginx-deployment.yml: no such file or directory': evalsymlink failure on '/home/nginx-deployment.yml' : lstat /home/nginx-deployment.yml: no such file or directory
The kubernetes is a single node.
Why I'm getting these errors and how may I run my container in this environment?

Answer 1

Your Kustomization.yml file has two errors. The files generated by kompose have .yaml extensions but you are referring to .yml and you are missing the kind and apiVersion lines.
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
- nginx-deployment.yaml
- nginx-service.yaml
kubectl apply -k .
