CloudFunction で CloudBuild をトリガーする

まずgcloudで既存のトリガーの一覧を確認しておく

$ gcloud beta builds triggers list

description: master ブランチへの push
filename: site/cloudbuild.yaml
github:
  name: test
  owner: admin
  push:
    branch: ^master$

nodejsで呼び出し

cloudbuildの公式npmパッケージがある

• googleapis/nodejs-cloudbuild: Cloud Build API client for Node.js

こんな感じでビルドをトリガーできる

import { CloudBuildClient } from '@google-cloud/cloudbuild';

const projectId = 'testproject-531612';
// gcloudで調べたidを入れる
const triggerId = '0e2bd416-129f-44a3-b7ed-79c3c61e021a'
const credentials = require('./credentials/cloudbuild-trigger.json');
const cloudbuild = new CloudBuildClient({ credentials });
const source = {
  projectId,
  dir: './',
  branchName,
};
await cloudbuild.runBuildTrigger({ projectId, triggerId, source });
