Google cloud platform 如何使用terraform平衡google计算实例的负载？

在我的terraform配置文件中，我这样定义我的资源：

resource "google_compute_instance" "test" {
    ...
    count = 2
}

---

我现在想要的是创建负载平衡器，它将平衡我的google compute实例的两个实例。不幸的是，我在文档中找不到与此任务相关的任何内容。似乎google_compute_target_pool或google_compute_lb_ip_ranges与我的问题无关。

您必须使用此地形上指示的“转发规则”。若要使用负载平衡和协议转发，必须创建一个转发规则，将流量定向到特定的目标实例。在云平台上使用您可以找到的转发规则。

在常见情况下，您可以使用以下内容：

resource "google_compute_instance" "test" {
    name         = "nlb-node${count.index}"
    zone         = "europe-west3-b"
    machine_type = "f1-micro"
    count        = 2

    boot_disk {
        auto_delete = true
        initialize_params {
            image       = "ubuntu-os-cloud/ubuntu-1604-lts"
            size        = 10
            type        = "pd-ssd"
        }
    }

    network_interface {
        subnetwork = "default"

        access_config {
            nat_ip = ""
        }
    }

    service_account {
        scopes = ["userinfo-email", "compute-ro", "storage-ro"]
    }
}

resource "google_compute_http_health_check" "nlb-hc" {
    name               = "nlb-health-checks"
    request_path       = "/"
    port               = 80
    check_interval_sec = 10
    timeout_sec        = 3
}

resource "google_compute_target_pool" "nlb-target-pool" {
    name             = "nlb-target-pool"
    session_affinity = "NONE"
    region           = "europe-west3"

    instances = [
        "${google_compute_instance.test.*.self_link}"
    ]

    health_checks = [
        "${google_compute_http_health_check.nlb-hc.name}"
    ]
}

resource "google_compute_forwarding_rule" "network-load-balancer" {
    name                  = "nlb-test"
    region                = "europe-west3"
    target                = "${google_compute_target_pool.nlb-target-pool.self_link}"
    port_range            = "80"
    ip_protocol           = "TCP"
    load_balancing_scheme = "EXTERNAL"
}

您可以通过${google\u compute\u forwarding\u rule.network load balancer.ip\u address}获取负载平衡器外部ip

谢谢你，先生！我会检查的！

// output.tf
output "network_load_balancer_ip" {
    value = "${google_compute_forwarding_rule.network-load-balancer.ip_address}"
}
