使用 gcloud 指令建立與調整 GCE 小記

使用 gcloud 指令建立與調整 GCE 小記

OS: Container with openSUSE Leap 15

工作上三個雲端平臺都會碰到, 所以就想要使用一些工具或是方式來節省時間

畢竟偷懶是工程師前進最大的動力 :p

有的時候會遇到因為業務需求, 要建立不同類型 / 自訂規格 的 VM, 或是, 變更 VM 的相關規格, 開關機器之類的要求

以下是一些自己在 GCP 上面的小記

感謝 宏庭科技 Joy 的幫忙, 讓我有方向前進, 來進行實驗還有撰寫 shell script

建立 自訂規格VM

# gcloud compute instances create --zone=asia-east1-b --custom-cpu 1 --custom-memory 4 --image-project=opensuse-cloud --image-family opensuse-leap --boot-disk-size=30GB test20191026 --project sakanatest

在 GCP 上面, gcloud 指令已經非常方便了, 我都覺得 Ansible 沒啥發揮空間了 :)

但是有的時候還是懶的慢慢打指令, 所以寫了 shell script 來方便執行

• read 的部分目前在 openSUSE Leap 15 上面驗證過 
• Mac 的部分可能還要調整, 不過後面再調整, 因為我都是跑在容器的 linux 內, 沒有影響

下次應該要弄使用 image 建立 VM 的 shell script :)

先記下來
