ENOENT when connecting to Google Cloud SQL from App Engine

Question

I\'m trying to deploy my Node.js app on Google App Engine and it deployed fine, but it can\'t connect to Google Cloud SQL for some reason. Here\'s what it throws:

Answer 1

make sure you have added following setting in app.yaml

beta_settings:
  # The connection name of your instance, available by using
  # 'gcloud beta sql instances describe [INSTANCE_NAME]' or from
  # the Instance details page in the Google Cloud Platform Console.
  cloud_sql_instances: YOUR_INSTANCE_CONNECTION_NAME

Answer 2

Apparently the order you do things matters...

1. enable Cloud SQL API
2. then (re)deploy your app (gcloud app deploy)

When I did deploy -> create databases -> enable sql ipi I got the ENOENT error

Answer 3

Check your logs for any errors during startup using:

1. the following cmd gcloud app logs tail -s default or,

2. with the log viewer https://console.cloud.google.com/logs/viewer

Chances are that you have not enabled the Cloud SQL API for your project: https://console.developers.google.com/apis/api/sqladmin/overview
