Running kubectl command from jenkins container

I installed minikube on a VirtualBox(ubuntu) to simulate a deploy environment and used Jenkins pipeline. On my jenkins container i also installed kubectl command to control minikube.

So i create the following stage:

stage("k8s command test") {                        
        withCredentials([usernamePassword(credentialsId: 'cbcba826-ef01-4b18-856f-e6dc4eb27c1f', usernameVariable: 'my-user', passwordVariable: 'PASSWORD')]) {
            sh """
                kubectl config view
                kubectl create -f /home/my-user/file-svc.yml
            """
        }
    }

First thing my cluster seems to be empty in output i have :

+ kubectl config view
apiVersion: v1
clusters: []
contexts: []
current-context: ""
kind: Config
preferences: {}
users: []

if i check .kube/config i have the following config :

apiVersion: v1
clusters:
- cluster:
    certificate-authority: /home/my-user/.minikube/ca.crt
    server: https://127.0.0.1:8443
  name: minikube
contexts:
- context:
    cluster: minikube
    user: minikube
  name: minikube
current-context: minikube
kind: Config
preferences: {}
users:
- name: minikube
  user:
    as-user-extra: {}
    client-certificate: /home/my-user/.minikube/client.crt
    client-key: /home/my-user/.minikube/client.key

As i'm new on kubernetes i need help to understand how to make possible the communication between jenkins and minikube.

consequently kubectl create -f /home/my-user/file-svc.yml raised an error about authentication. I read many article kubectl need certificate to be connected to the API server how can i do that in jenkins
