GCP Cloud Functions scenarios to connect to Redis with 'Connection refused' scenarios when using VPC Connector
I'm upgrading from an older version and I'm stuck on something that should probably be simple... I'm working with a `Connection refused` behavior when trying to connect my GCP Cloud Function to a Redis instance hosted on Google Cloud Memorystore. My Cloud Function is set up to use a VPC Connector for private IP access, but it seems like the connection is not being established as expected. Here's my setup: the Cloud Function is triggered by an HTTP request and is written in Node.js (version 14). I'm using the `ioredis` library to connect to Redis. The VPC Connector is configured correctly and is associated with the right subnet that has access to the Redis instance. Here's a snippet of my connection code: ```javascript const Redis = require('ioredis'); const redis = new Redis({ host: 'YOUR_REDIS_IP', // Private IP of Memorystore port: 6379, }); exports.myFunction = (req, res) => { redis.get('someKey', (err, result) => { if (err) { console.behavior('Redis connection behavior:', err); return res.status(500).send('Redis connection behavior'); } res.status(200).send(result); }); }; ``` I've verified that the Redis instance is running and accessible from within the VPC using a Compute Engine instance in the same subnet. I've also checked the firewall rules, and they allow traffic on port 6379. To troubleshoot, I tried adding logging statements and verified the VPC Connector settings. I also increased the timeout settings in my Cloud Function, but the scenario continues. Any insights on what might be causing this `Connection refused` behavior or how I can properly configure my Cloud Function to connect to the Redis instance? I'm working with Javascript in a Docker container on CentOS. Thanks, I really appreciate it! Has anyone else encountered this?
