Host is set correctly in the variables

2 years ago

you are still using shared variables

2 years ago

please see this for ioredis

2 years ago

2 years ago

i have applied everything from the railway docs

2 years ago

please stop using shared variables for this

2 years ago

use reference variables

2 years ago

ok changed from shared variables, using reference vars from redis service

2 years ago

Redis port has gone blank on the redis service

2 years ago

use the private url variable please

2 years ago

just like the example in the docs shows

2 years ago

Ok using the private url string only works. But i wonder why you cannot construct using the options with all the same details

2 years ago

probably just configured it wrong

Hi sorry to bring this back up, but I'm not able to see the messages on discord, and I think many links are missing here.

What is the right solution to get a redis instance running within the same project? I'm having issues with the host being undefined.

"just like the example in the docs shows" does anyone have links to these docs please?

No worries, the links are indeed missing.

Getting ioredis setup correctly with private networking checklist -

Make sure you have the V2 runtime enabled in your service settings.
Use the URL syntax for the ioredis client as shown here - https://github.com/redis/ioredis/blob/main/README.md#connect-to-redis
Use environment variables - REDIS_URL=${{Redis.REDIS_PRIVATE_URL}}
Append ?family=0 to the end of the URL.

Example -

const redis = new Redis(process.env.REDIS_URL + "?family=0");

Hi, I'm still having this exact issue.

I'm running:
ioredis 5.5.0
node 22.8.0

I'm configuring the redis instance like this:
```

const redisClient = new Redis(`${process.env.REDIS_URL}?family=0`, {
    tls: { rejectUnauthorized: false },
    lazyConnect: true,
    connectTimeout: 15000,
    retryStrategy: (times) => Math.min(times * 30, 1000),
  });

```

My redis url looks like this when I print it out: redis://default:yyBqSILlgwiYDnZOPgvQELaUAmvKLjgc@redis.railway.internal:6379

I'm using setting the REDIS_URL variable like this on railway: ${{Redis.REDIS_URL}}

Also regarding @brody's checklist, "ensure V2 runtime enabled" - I cannot see such on option on either my redis-service or my backend-service config. Is there another way to configure this?

One thing to note is that my redis service is deployed in a US region while the backend is in europe. Ofc I'd want them both in Europe but its currently not an option on the hobby plan.

Thanks in advance!

Can you please open your own help thread, a new thread would be preferable over an 8 month old thread.
