Connecting to a Redis cluster in GCP memorystore for redis cluster locally

[tituscarl]

Hi, does anyone knows or have an idea how to solve this problem? We have a memorystore for redis cluster in GCP, and I want to connect to it locally, I tried this guide and it works using redis-cli but when using a redis-client in go for example rueidis it says connection refuse with an address. I assume that the address on the error message is one of the nodes of the clsuter, but is there any reason that it does not connect while using redis-cli does? I tried PING command on cli and on code but only cli works.

Hi @tituscarl,

The link you provided is "Connecting from a local machine with port forwarding". I believe the method only supports standalone redis. redis cluster requires the client to connect to each redis node directly and simple port forwarding is not enough.

In local no, but no issues in prod with just the discovery endpoint.

The config I send doesn't work also, the first address maps to the discovery endpoint and the 2 are for the nodes address that is also mapped to the forwarded port.

In local no, but no issues in prod with just the discovery endpoint.

That was expected. What error did you see when using rueidis with the discovery endpoint in prod?

[tituscarl]

The issue is only on local, I think the problem is not in rueidis. But yeah although it works in prod, I just want to access it in local for some testing.

I understand. However, a client still needs to follow the discovery endpoint. It should connect each redis instance in the way the discovery endpoint requested. So you need to somehow translate the production addresses to your local ports on the fly. Putting local addresses in the initialization config of a client will not work.
