节点可用3 CPU不足

Question

我正在尝试运行以下示例：https://kubernetes.io/docs/tutorials/stateful-application/cassandra/ 当我在minikube上运行时，它运行良好。但是，当我在GKE上运行时，看到一个错误0/3 nodes are available: 3 Insufficient cpu.

有人可以帮助我吗？

我可以在哪里增加CPU？在stateful_set还是在kluster配置上？

我用terraform创建了集群，并具有以下配置：

resource "google_container_cluster" "gcloud_cluster" {
  name               = "gcloud-cluster-${var.workspace}"
  zone               = "us-east1-b"
  initial_node_count = 3
  project            = "${var.project}"

  addons_config {
    network_policy_config {
      disabled = true
    }
  }

  master_auth {
    username = "${var.username}"
    password = "${var.password}"
  }

  node_config {
    oauth_scopes = [
      "https://www.googleapis.com/auth/devstorage.read_only",
      "https://www.googleapis.com/auth/logging.write",
      "https://www.googleapis.com/auth/monitoring",
      "https://www.googleapis.com/auth/service.management.readonly",
      "https://www.googleapis.com/auth/servicecontrol",
      "https://www.googleapis.com/auth/trace.append",
      "https://www.googleapis.com/auth/compute",
    ]
  }
}

谢谢

这里发生的是，默认情况下，群集是使用仅具有1vCPU的n1-standard-1机器创建的。

您应在配置中添加有关要使用的计算机类型的信息，即：

resource "google_container_cluster" "gcloud_cluster" {
  name               = "gcloud-cluster-${var.workspace}"
  zone               = "us-east1-b"
  initial_node_count = 3
  project            = "${var.project}"

  addons_config {
    network_policy_config {
      disabled = true
    }
  }

  master_auth {
    username = "${var.username}"
    password = "${var.password}"
  }

  node_config {
    machine_type = "${var.machine_type}"
    oauth_scopes = [
      "https://www.googleapis.com/auth/devstorage.read_only",
      "https://www.googleapis.com/auth/logging.write",
      "https://www.googleapis.com/auth/monitoring",
      "https://www.googleapis.com/auth/service.management.readonly",
      "https://www.googleapis.com/auth/servicecontrol",
      "https://www.googleapis.com/auth/trace.append",
      "https://www.googleapis.com/auth/compute",
    ]
  }
}

并使用n1-standard-2或n1-standard-4在变量.tf文件中声明它，即：

variable "machine_type" {
    type = "string"
    default = "n1-standard-4"
}
