How to deploy airflow using kubernetes and kustomize - kubernetes

Question

I'm running minikube and I want to deploy airflow using kustomize instead of helm.
So first I got the docker-compose.yaml
curl -LfO 'https://airflow.apache.org/docs/apache-airflow/2.5.0/docker-compose.yaml'
Then I execute kompose convert, to convert the docker-compose to kubernetes yaml.
After I change the service files to type: LoadBalancer.
Then I deploy all those file generated by the kompose, all pods are running.
I start minikube tunnel
I was expecting to get the airflow ui on the url localhost:8080
However I'm getting
The connection was reset
What am I doing wrong?
I try to change the ports from 8080 to 8060
I saw the logs for each pod using kubectl logs <pod-name> but no error appear
I try using the url generate by this cmd
minikube service airflow-webser --url
Here is my docker-compose.yaml that I modify to work with kompose
