Hi @MutedJam
Can we use redis as Redis sentinels or Redis Cluster in queue mode ?
I dont see any option to set sentinel , master name etc env variables :pray:

Hi @Pooja, I am not familiar with Redis Sentinel I am afraid. I’d be very surprised if we had any custom logic for this built in, but perhaps @krynble can confirm?

@krynble could you please help here :slight_smile:

Hey @Pooja,

From what I can tell looking at the docs for Bull and our implementation it is currently not possible so it may need a feature request for Sentinels

Hey @Pooja sorry for taking so long, but as Jon mentioned, it is currently not possible. Only “regular” Redis installations work for queue mode.

I’ve just had a crack at this, working fine in my limited testing so far - ✨ Add Redis Sentinel support by pemontto · Pull Request #5350 · n8n-io/n8n · GitHub

Any upgrade on this? We also need sentinel/cluster support.

Hey @Mustafa_fimple,

Nothing at the moment, We do support Redis clusters but not Sentinel.

Hi,
I’m installing an n8n 3 nodes cluster in queue mode.
I’m using an external patroni postgres cluster and a redis cluster, and I’d like to configure n8n to use the redis cluster, but I can’t find how in the docs.
As far as I know the redis connection to the cluster nodes has to be managed on the client side, but in the documentation I can see the option to use only one endpoint for redis.
Can you please point me to the right piece of documentation?
thank you
Antonio
