如果要选择GCP为云平台，则经常需要创建GCE(Google Compute Engine)，有以下几种方式：

(1) 在浏览器创建

(2) 命令 gcloud

(3) Terraform

在开始之前，可以查看：《初始化一个GCP项目并用gcloud访问操作》。

2 GCP Console

登陆操作界面，点击创建按钮，然后选择好参数即可：

3 gcloud命令

在操作界面创建时，可以直接查看对应的gcould命令：

我们直接运行就可以创建了：

$ gcloud compute instances create pkslow-vm \
--project=pkslow \
--zone=us-west1-a \
--machine-type=e2-micro \
--network-interface=network-tier=PREMIUM,subnet=default \
--maintenance-policy=MIGRATE \
[email protected] \
--scopes=https://www.googleapis.com/auth/cloud-platform \
--tags=http-server,https-server \
--create-disk=auto-delete=yes,boot=yes,device-name=instance-1,image=projects/centos-cloud/global/images/centos-8-v20211105,mode=rw,size=20,type=projects/pkslow/zones/us-west1-a/diskTypes/pd-standard \
--no-shielded-secure-boot \
--shielded-vtpm \
--shielded-integrity-monitoring \
--reservation-affinity=any

Created [https://www.googleapis.com/compute/v1/projects/pkslow/zones/us-west1-a/instances/pkslow-vm].
NAME       ZONE        MACHINE_TYPE  PREEMPTIBLE  INTERNAL_IP  EXTERNAL_IP     STATUS
pkslow-vm  us-west1-a  e2-micro                   10.138.0.5   34.145.124.xxx  RUNNING

                10.138.0.5   34.145.124.xxx  RUNNING

检查是否创建成功：

$ gcloud compute instances list
NAME       ZONE        MACHINE_TYPE  PREEMPTIBLE  INTERNAL_IP  EXTERNAL_IP     STATUS
pkslow-vm  us-west1-a  e2-micro   

4 Terraform

当然，最佳实践是使用Terraform来管理，代码简单易懂，具体如下：

provider "google" {
  project     = "pkslow"
}

resource "google_compute_instance" "test" {
  name         = "pkslow-test"
  machine_type = "e2-micro"
  zone         = "us-west1-a"

  tags = ["http-server", "https-server"]

  boot_disk {
    initialize_params {
      image = "projects/centos-cloud/global/images/centos-8-v20211105"
    }
  }


  network_interface {
    network = "default"

    access_config {
      // Ephemeral public IP
    }
  }

  metadata = {
    foo = "bar"
  }

  metadata_startup_script = "echo hi > /test.txt"

  service_account {
    # Google recommends custom service accounts that have cloud-platform scope and permissions granted via IAM Roles.
    email  = "[email protected]"
    scopes = ["cloud-platform"]
  }
}

检查是否创建成功：

$ gcloud compute instances list
NAME         ZONE        MACHINE_TYPE  PREEMPTIBLE  INTERNAL_IP  EXTERNAL_IP     STATUS
pkslow-test  us-west1-a  e2-micro                   10.138.0.6   34.83.138.xxx   RUNNING
pkslow-vm    us-west1-a  e2-micro                   10.138.0.5   34.145.124.xxx  RUNNING
