How to use redis in n8n

[nebulon]

This is currently only possible on Cloudron if we add the redis addon to the n8n package in the CloudronManifest.json.

Given that this is a separate docker container, can you give more background for what it is used there and with which extension, so we can discuss if its worth it or if we should seek some other custom solution.

@nebulon but in that way i should update n8n manualy? there are not a way to make it run with a enviroment variable?

[nennogabriel]

@nebulon nice... i follow the docs and get it working

I will lost automatic updates, but ok. I have redis now

[robi]

couldn't one simply use any existing redis service from another container?

[girish]

@nennogabriel we will look into adding "optional redis" in the coming releases.

[nennogabriel]

@robi yes. I didnt thing about this. simple and good.

Hi !
I'm looking at your services, and wonder if Posgresql and Redis are integrated into your instances of n8n ?
Thanks !

[nebulon]

The main database for the n8n package is Postgres on Cloudron and that is integrated. Redis is not at the moment.

@nebulon thanks for your reply ! If I do have an external Redis, on the same hoster, but as you said, not integrate within Cloudron, should I use Redis with n8n ?

[nebulon]

You should be able to integrate your external redis via env variables https://docs.cloudron.io/apps/n8n/#custom-env

upstream docs for this are at https://docs.n8n.io/hosting/configuration/environment-variables/queue-mode/
