使用 Kompose 将 docker-compose 转换为 kubernetes

Question

Im new to Kubernetes and i saw that there is a way runing Kompose up, but i get this error:

root@master-node:kompose --file docker-compose.yml --volumes hostPath up
INFO We are going to create Kubernetes Deployments, Services and PersistentVolumeClaims for your Dockerized application. If you need different kind of resources, use the 'kompose convert' and 'kubectl create -f' commands instead.

FATA Error while deploying application: Error loading config file "/etc/kubernetes/admin.conf": open /etc/kubernetes/admin.conf: permission denied

ls -l /etc/kubernetes/admin.conf
-rw------- 1 root root 5593 Jun 14 08:59 /etc/kubernetes/admin.conf

How can i make this work?

system info: ubuntu18 Client Version: version.Info: Major:"1", Minor:"21"

I also tried making it work like that:

kompose convert --volumes hostPath
INFO Kubernetes file "postgres-1-service.yaml" created
INFO Kubernetes file "postgres-2-service.yaml" created
INFO Kubernetes file "postgres-1-deployment.yaml" created
INFO Kubernetes file "postgres-2-deployment.yaml" created

I get this error only on postgres-1-deployment.yaml and postgres-2-deployment.yaml.
