1 简介
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：
会显示出对应的价格。
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 --service-account=admin-for-all@pkslow.iam.gserviceaccount.com --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 = "admin-for-all@pkslow.iam.gserviceaccount.com" 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 也可以界面上查看：
