• You can update the authenicaion certificates. Get your own one via minikube config view

provider "kubernetes" {
    # Note: replace with your own configurations
    host                   = "https://172.16.58.128:8443"
    client_certificate     = file("~/.minikube/profiles/minikube/client.crt")
