如何指定 Google Cloud Function 的区域? [英] How can I specify the region of a Google Cloud Function?

问题描述

我目前正在使用 Google Cloud Function 来构建我的 Restful API.但是，我发现它很慢，因为我的 Google-Cloud-Function 服务器在us-central"上，而我的服务在亚洲.

我尝试将我的 Google 项目的默认区域更改为asia-west-1"并重新启动云功能 - 我按照概述的步骤操作

点击它会显示一个Region下拉菜单(以及其他高级设置):

使用 gcloud

只需使用 --region 标志指定四个可用区域之一.

最小工作示例

假设你有

$ 树..└── index.js0 个目录，1 个文件$猫 index.jsexport.hello = (req, res) =>{res.send(`你好世界！`);}

然后运行

gcloud 函数部署 hello --region asia-northeast1 --trigger-http

应该将函数hello部署到区域asia-northeast1:

I'm currently using Google Cloud Function to build up my restful API. However, I've found that it's slow because the my Google-Cloud-Function server is on "us-central", whereas my service is in Asia.

I tried to change the default region of my Google Project to "asia-west-1" and restart the cloud function—I followed the steps outlined here—but, unfortunately, it's still in "us-central". How can I change the function's region ?

解决方案

No such region as "asia-west-1"

There is no such region as "asia-west-1" on the Google Cloud Platform. At the time of writing, GCP provides the following regions in Asia:

• asia-east1
• asia-northeast1
• asia-south1
• asia-southeast1

However, asia-northeast1 is currently the only GCP region in Asia available for Google Cloud Functions:

$ gcloud functions regions list
NAME
projects/xxxxxxxx/locations/europe-west1
projects/xxxxxxxx/locations/us-east1
projects/xxxxxxxx/locations/us-central1
projects/xxxxxxxx/locations/asia-northeast1

How to specify the region of a Google Cloud Function

Using Google Cloud Console

The region setting is easy to miss. It's actually hidden behind an accordion entitled "More":

Clicking on it reveals a Region dropdown (among other advanced settings):

Using gcloud

Simply specify one of the four available regions using the --region flag.

Minimal working example

Under the assumption that you have

$ tree .
.
└── index.js

0 directories, 1 file
$ cat index.js 
exports.hello = (req, res) => {

  res.send(`Hello World!`); 

}

then running

gcloud functions deploy hello --region asia-northeast1 --trigger-http

should deploy function hello to region asia-northeast1:
