我正在学习使用Terraform在DO上创建k8s集群的方法,我一直在尝试获取我已创建的单个K8s节点的ID,并从负载均衡器中引用它。

这样做的主要原因是,我可以在.tf文件中声明FQDN。

首先,这是集群声明:


variable "digitalocean_token" {}

provider "digitalocean" {
  token = "${var.digitalocean_token}"
}

resource "digitalocean_kubernetes_cluster" "foo" {
  name    = "foo"
  region  = "nyc1"
  version = "1.12.1-do.2"

  node_pool {
    name       = "woker-pool"
    size       = "s-1vcpu-2gb"
    node_count = 1
  }
}


这是负载均衡器声明:
resource "digitalocean_loadbalancer" "foo" {
  name = "k8s-lb.nyc1"
  region = "nyc1"

  forwarding_rule {
    entry_port = 80
    entry_protocol = "http"

    target_port     = 80
    target_protocol = "http"
  }
  droplet_ids = ["${digitalocean_kubernetes_cluster.foo.node_pool.0.id}"]
}

output "loadbalancer_ip" {
  value = "${digitalocean_loadbalancer.foo.ip}"
}

resource "digitalocean_record" "terraform" {
  domain = "example.com" # "${digitalocean_domain.example.name}"
  type   = "A"
  name   = "terraform"
  value  =  "${digitalocean_loadbalancer.foo.ip}"
}

# Output the FQDN for the record
output "fqdn" {
  value = "${digitalocean_record.terraform.fqdn}"
}


我猜想也许digitalocean_loadbalancer资源仅设置为可与单个小滴一起使用?

这是输出错误:当我运行terraform apply时:
* output.loadbalancer_ip: Resource 'digitalocean_loadbalancer.foo' not found for variable 'digitalocean_loadbalancer.foo.ip'

* digitalocean_record.terraform: Resource 'digitalocean_loadbalancer.foo' not found for variable 'digitalocean_loadbalancer.foo.ip'

* digitalocean_loadbalancer.foo: droplet_ids.0: cannot parse '' as int: strconv.ParseInt: parsing "d4292e64-9c0a-4afb-83fc-83f239bcb4af": invalid syntax

我添加了digitalocean_droplet资源,以查看将什么样的ID传递给负载均衡器。
resource "digitalocean_droplet" "web" {
  name      = "web-1"
  size      = "s-1vcpu-1gb"
  image     = "ubuntu-18-04-x64"
  region    = "nyc1"
}
digitalocean_kubernetes_cluster.foo.node_pool.0.id = '6ae6a787-d837-4e78-a915-cb52155f66fe'digitalocean_droplet.web.id = 132533158

最佳答案

因此,digitalocean_loadbalancer资源具有一个可选的droplet_tag参数,可用于提供给创建的节点/液滴的通用标签。

但是,当在kubernetes中声明一个负载均衡器时,仍然会创建一个新的负载均衡器。因此,至少目前看来,在digitalocean上无法使用Terraform定义域/ CNAME记录
