4. 建立 Instance Template for Custom Image (via web)
   • Boot Disk: Custom Image
   • Region: Global (Recommend)
5. 用 Instance Template 新增多個 VM Instances（via CLI or web） 

# sets up the authentication
gcloud init

# create new VM instances with the template named vm1-template
gcloud compute instances create --zone "Zone" --source-instance-template vm1-template vm2 vm3 vm4 vm5 vm6 vm7 vm8
gcloud compute instances list

其他方式大量部署 VM

• Getting started on GCP with Terraform

• Creating groups of unmanaged instances

Active Cloud Shell

Cloud Shell is a virtual machine that is loaded with development tools. It offers a persistent 5GB home directory and runs on the Google Cloud. Cloud Shell provides command-line access to your Google Cloud resources.

Tip: Cloud Shell 環境已經預裝好 GCP SDK, docker 等開發工具，可以用來執行 gcloud 指令，或者簡易的 docker 操作。

在 GCP 控制台點擊右上角 Activate Cloud Shell。
