Unable to connect to MemoryStore instance (GKE, Node.js)

Question

My Redis host is '10.0.0.x', port is 6379, and I made sure my k8s cluster which hosts Node.js pods and MemoryStore are in the same region, but it still times out when trying to connect.

var Redis = require('ioredis');
var redis = new Redis({
    port: 6379,          // Redis port
    host: '10.0.0.x',   // Redis host
})
redis.on('connect', () => console.log('connected'))

Am I missing a step?

I had to enable VPC Native Alias IP in the Kubernetes Engine dashboard.
