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
