Configuration Helm and Kubernetes providers

provider "kubernetes" {
  host                   = # reference cluster endpoint
  cluster_ca_certificate = # reference cluster ca certificate base64decode
  token                  = # reference access token
}

provider "helm" {
  kubernetes {
    host                   = # reference cluster endpoint
    cluster_ca_certificate = # reference cluster ca certificate base64decode
    token                  = # reference access token
  }
}
