connecting to AWS ElasticCache

Hi, I’m moving resources from Azure to AWS and am having trouble connecting to Elasticache through ioredis.

Here’s my basic config:

const redisClient = new Redis({
  port: process.env.REDIS_PORT,
  host: process.env.REDIS_HOST
})

Here’s my Elasticache instance:

When trying to connect, it just times out. The strange thing is that if I use node-redis with essentially the same config, it connects immediately.

Anything special that needs to be done?

Thx!

Had the same “problem” yesterday, solved it by a coworker who had gone through the same problem some time ago. Posting my solution, maybe it helps out someone else.

You need to add tls: {} to the options, which is a bit counter-intuitive given the API docs and examples.

const Redis = require("ioredis");
const redis = new Redis({
  host: "master.prodGETFROMENVSECRETS.amazonaws.com",
  port: 6379,
  password: "myl33tpa5w00rd",
  tls: {}
});

Use lazyConnect: true and connect manually with await redis.connect();
