Gitea with redis cluster

Install/Maintain/Configure
1

Hi ,

I am setting up a gitea deployment in k8s environment. For session and cache I am using a external redis cluster .

The redis cluster is configured as a stateful set and has a headless service created to access it.

The connection uri for redis from gitea is configured as below ,

redis://user:@my-cluster:6379?pool_size=100&idle_timeout=180s

The settings work properly when the redis cluster is configured with single node.

When more than 1 node is configured , I am getting “500 Internal Server” error during login.

Logs from gitea pod

Is there any setting for redis cluster with multiple nodes.

With regard to Config Cheat Sheet | Gitea Documentation, you have to change the connection string slightly for a multi-node Redis cluster to

redis+cluster://123@127.0.0.1:6379/0

Note especially the redis+cluster. Does that help?

Actually I am trying to connect the redis instance via the headless service. Hence I am using only “redis” in the connection string.

But I also tried using redis+cluster in the connection string and there was no communication between gitea and redis cluster in that case.
