I run both n8n and redis as Docker containers on a single CapRover instance. CapRover uses Docker Swarm as orchestrator, and as far as I understand the containers are all visible one to another because they belong to the same Docker network:
CapRover allows the deployment of one-click apps, that are basically Docker images with some additional configuration for Nginx. This is the one-click app for Redis:
And this is how I configured the Redis credentials in n8n:
With this setup the redis node in n8n doesn’t seem to connect and the spinner keeps spinning. I don’t see any errors in the UI.
I also tried to replace Host with
0.0.0.0, but with no avail. I think I have the same Docker issue described here.
If I configure port mapping on the Redis container (from the CapRover UI) and I run
n8n start from my laptop (without Docker) I can connect without any issue. E.g. here I’m using Redis Desktop Manager.
