NodeJS AppEngine App error connecting to Google Cloud SQL

[cristian....@gmail.com]

Hi,

     I'm trying to connect a simple NodeJS App (A REST API) deployed into AppEngine to a Google Cloud SQL instance.

     Every time I deploy the app using a flex environment, it works perfectly, but when I try to deploy it in a Standard environment it does not work.

     To isolate the problem I've created a repo with a simple nodeJS app which proves my scenarios. 

     Is it by design? I mean, the filter in ports blocking the connection from Standard AppEngine to Google Cloud SQL instances?

     I've tried the same code using Cloud Run and it is not working too.    

Regards

Cristian

Your connection string doesn't look right to me. Check out this example: https://cloud.google.com/appengine/docs/standard/nodejs/using-cloud-sql#setting_connection_strings_and_adding_a_library

What do you mean by doesn't look right to me?

I deploy exactly the same code in Standard and it does not work, but if I deploy it using Flex, it does work.

The connection technique is different in Standard I believe.

In particular, note the "config.socketPath" in the link I sent.

The connection string cannot have IP address in App Engine Standard. It should you Instance Connection Name.

https://www.youtube.com/watch?v=T0P6qsTuh1s will explain basics of App Engine Standard. 

If you want to using IP address then Serverless VPC https://cloud.google.com/vpc/docs/configure-serverless-vpc-access

Thank
