您好我正在尝试获取服务的外部 IP。我可以在 azure 控制台中看到 externalIp，但数据对象不包含它。

resource "kubernetes_manifest" "haproxy_controller_svc" {
  manifest = yamldecode(file("${path.root}/k8s/ingress/controller.svc.yaml"))
}

output "ingress_external_ip" {
  value = kubernetes_manifest.haproxy_controller_svc.object.spec.externalIPs[0]
}

$ tf apply
 Error: Attempt to index null value
│ 
│   on ingress.tf line 61, in output "ingress_external_ip":
│   61:   value = kubernetes_manifest.haproxy_controller_svc.object.spec.externalIPs[0]
│     ├────────────────
│     │ kubernetes_manifest.haproxy_controller_svc.object.spec.externalIPs is null
│ 
│ This value is null, so it does not have any indices.

由于入口已经存在并且有一个 IP（来自之前的 tf apply）。在这一点上，我不认为这是因为尚未在 Azure 中配置负载均衡器。我再次可以在仪表板上看到它。

如果我打印完整的对象。它看起来像这样。

kubectl 的状态描述：

为了测试，我手动获取服务数据。

data "kubernetes_service" "test" {
  metadata {
    name = "haproxy-ingress"
    namespace = "ingress"
  }
}

output "test_svc_state" {
    value = data.kubernetes_service.test.status
}

test_svc_state = tolist([
  {
    "load_balancer" = tolist([
      {
        "ingress" = tolist([
          {
            "hostname" = ""
            "ip" = "1.2.3.4"
          },
        ])
      },
    ])
  },
])
