无法从 App Engine Node JS 标准环境连接 Google Cloud MySQL 实例

Question

Not able to connect MySQL Google Cloud Instance Database from NodeJS/Express App Engine.

Able to connect Database locally as I have added my local machine IP in "Authorized networks" of SQL Instance Settings.

Tried using below code in NodeJS App Engine Instance but facing error not able to connect db.

{
    "username": "abcd",
    "password": "abcd123",
    "database": "dummy",
    "host": "localhost",
    "socketPath": "/cloudsql/{project-name}:{instance-zone}:{instance-name}",
    "post": 3306,
    "dialect": "mysql",
    "dialectOptions": {
          "socketPath": "/cloudsql/{project-name}:{instance-zone}:{instance-name}"
    }
  }

How can I solve this issue?

Answer 1

Having the Cloud SQL MySQL Instance on a different project as the GAE app caused trhe issue.

Just moving the isntance solved the issue

I think you need vpc_access_connector in app.yaml.

or you can follow sample code from gcp app engine nodejs https://github.com/GoogleCloudPlatform/nodejs-docs-samples/tree/master/appengine/cloudsql
