Kubernetes 在GKE集群上使用Terraform部署Helm工作负载

我试图使用Terraform Helm provider（）将工作负载部署到GKE集群

我或多或少地遵循Google的例子，但我确实希望通过手动创建服务帐户来使用RBAC

我的helm.tf看起来像这样：

variable "helm_version" {
  default = "v2.13.1"
}

data "google_client_config" "current" {}

provider "helm" {
  tiller_image = "gcr.io/kubernetes-helm/tiller:${var.helm_version}"
  install_tiller = false # Temporary

  kubernetes {
    host                   = "${google_container_cluster.data-dome-cluster.endpoint}"
    token                  = "${data.google_client_config.current.access_token}"

    client_certificate     = "${base64decode(google_container_cluster.data-dome-cluster.master_auth.0.client_certificate)}"
    client_key             = "${base64decode(google_container_cluster.data-dome-cluster.master_auth.0.client_key)}"
    cluster_ca_certificate = "${base64decode(google_container_cluster.data-dome-cluster.master_auth.0.cluster_ca_certificate)}"
  }
}


resource "helm_release" "nginx-ingress" {
  name  = "ingress"
  chart = "stable/nginx-ingress"

  values = [<<EOF
rbac:
  create: false
controller:
  stats:
    enabled: true
  metrics:
    enabled: true
  service:
    annotations:
      cloud.google.com/load-balancer-type: "Internal"
    externalTrafficPolicy: "Local"
EOF
  ]

  depends_on = [
    "google_container_cluster.data-dome-cluster",
  ]
}

这发生在我手动创建Helm RBAC并安装Tiller之后

我以前也尝试过设置“install_tiller=true”，但在安装tiller时出现了完全相同的错误

“kubectl get pods”没有任何问题

这个用户“客户端”是什么？为什么禁止它访问集群

感谢

为服务帐户和群集角色绑定创建资源对我来说非常有效：

resource "kubernetes_service_account" "helm_account" {
  depends_on = [
    "google_container_cluster.data-dome-cluster",
  ]
  metadata {
    name      = "${var.helm_account_name}"
    namespace = "kube-system"
  }
}

resource "kubernetes_cluster_role_binding" "helm_role_binding" {
  metadata {
    name = "${kubernetes_service_account.helm_account.metadata.0.name}"
  }
  role_ref {
    api_group = "rbac.authorization.k8s.io"
    kind      = "ClusterRole"
    name      = "cluster-admin"
  }
  subject {
    api_group = ""
    kind      = "ServiceAccount"
    name      = "${kubernetes_service_account.helm_account.metadata.0.name}"
    namespace = "kube-system"
  }
  provisioner "local-exec" {
    command = "sleep 15"
  }
}

provider "helm" {
  service_account = "${kubernetes_service_account.helm_account.metadata.0.name}"
  tiller_image = "gcr.io/kubernetes-helm/tiller:${var.helm_version}"
  #install_tiller = false # Temporary

  kubernetes {
    host                   = "${google_container_cluster.data-dome-cluster.endpoint}"
    token                  = "${data.google_client_config.current.access_token}"

    client_certificate     = "${base64decode(google_container_cluster.data-dome-cluster.master_auth.0.client_certificate)}"
    client_key             = "${base64decode(google_container_cluster.data-dome-cluster.master_auth.0.client_key)}"
    cluster_ca_certificate = "${base64decode(google_container_cluster.data-dome-cluster.master_auth.0.cluster_ca_certificate)}"
  }
}

当您在集群（Tiller）上安装Helm时，是否在运行

Helm init

时指定了

--service account

标志？如果你想通过terraform安装Tiller，你还需要添加

服务\u帐户

属性。我指定了

--服务帐户

你能描述一下服务帐户吗，即

kubectl Descripte clusterrole

并将其添加到你的帖子中吗？

resource "kubernetes_service_account" "helm_account" {
  depends_on = [
    "google_container_cluster.data-dome-cluster",
  ]
  metadata {
    name      = "${var.helm_account_name}"
    namespace = "kube-system"
  }
}

resource "kubernetes_cluster_role_binding" "helm_role_binding" {
  metadata {
    name = "${kubernetes_service_account.helm_account.metadata.0.name}"
  }
  role_ref {
    api_group = "rbac.authorization.k8s.io"
    kind      = "ClusterRole"
    name      = "cluster-admin"
  }
  subject {
    api_group = ""
    kind      = "ServiceAccount"
    name      = "${kubernetes_service_account.helm_account.metadata.0.name}"
    namespace = "kube-system"
  }
  provisioner "local-exec" {
    command = "sleep 15"
  }
}

provider "helm" {
  service_account = "${kubernetes_service_account.helm_account.metadata.0.name}"
  tiller_image = "gcr.io/kubernetes-helm/tiller:${var.helm_version}"
  #install_tiller = false # Temporary

  kubernetes {
    host                   = "${google_container_cluster.data-dome-cluster.endpoint}"
    token                  = "${data.google_client_config.current.access_token}"

    client_certificate     = "${base64decode(google_container_cluster.data-dome-cluster.master_auth.0.client_certificate)}"
    client_key             = "${base64decode(google_container_cluster.data-dome-cluster.master_auth.0.client_key)}"
    cluster_ca_certificate = "${base64decode(google_container_cluster.data-dome-cluster.master_auth.0.cluster_ca_certificate)}"
  }
}
