#

nixpacks or dockerfile?

cloud bone Mar 5, 2024, 4:02 PM

#

nixpacks with the sleep command in the package.json start command

stable matrix Mar 5, 2024, 4:03 PM

#

Host is set correctly in the variables

stable matrix Mar 5, 2024, 4:17 PM

#

you are still using shared variables

#

please see this for ioredis https://docs.railway.app/guides/private-networking#known-configuration-requirements-for-ipv6

cloud bone Mar 5, 2024, 4:20 PM

#

#

i have applied everything from the railway docs

stable matrix Mar 5, 2024, 4:20 PM

#

please stop using shared variables for this

#

use reference variables

cloud bone Mar 5, 2024, 4:22 PM

#

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

#

Redis port has gone blank on the redis service

stable matrix Mar 5, 2024, 4:30 PM

#

use the private url variable please

#

just like the example in the docs shows

cloud bone Mar 5, 2024, 4:48 PM

#

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

stable matrix Mar 5, 2024, 4:52 PM

#

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.

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-redisUse environment variables.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:[email protected]: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?
Thanks in advance!

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