I am trying to run temporal-potsgres.yaml under k8s folder of docker-compose repo , but frontend and worker pods are going to CrashBackOff state and throwing Error :- Unable to create server. Error: could not build arguments for function “[go.uber.org/fx](http://go.uber.org/fx)”.(\*App).failed to build log.Logger: received non-nil error from function “[go.temporal.io/server/temporal](http://go.temporal.io/server/temporal)”.ServerOptionsProvider, cassandra schema version compatibility check failed: version mismatch for keyspace/da **strong text** tabase: “temporal”. Expected version: 1.7 cannot be greater than Actual version: 0.0 temporaltest-history, temporaltest-matching and temporaltest-frontend are crashing again and again Can anyone please help me understanding the actual issue here as I am using postgresql so why it’s asking for cassandra support ? Or what actual is happening here ? Also if anyone can help me regarding postgresql specific installation for K8s , some steps are missing under example in documentation ---

Hey @antonio.perez , yes following the same article – docker-compose/KUBERNETES.md at main · temporalio/docker-compose · GitHub]([docker-compose/KUBERNETES.md at main · temporalio/docker-compose · GitHub](https://github.com/temporalio/docker-compose/blob/main/KUBERNETES.md)) ---

Above issue is resolved now but now my worker is not connecting to port 7233 , already being forwarded . It is throwing **unable to create Temporal client failed reaching server: last connection error: connection error: desc = “transport: Error while dialing: dial tcp [::1]:7233: connect: connection refused”** **exit status 1** Any Idea regarding that ? ---

@shivan_trivedi , can you check if you can connect from the command line ```auto grpcurl -plaintext -d '{"service": "temporal.api.workflowservice.v1.WorkflowService"}' :7233 grpc.health.v1.Health/Check ``` ---

@antonio.perez Failed to dial target host “127.0.0.1:7233”: dial tcp 127.0.0.1:7233: connect: connection refused Basically I am running worker on my local machine and temporal on minikube and trying to connect it via port forwarding , Is this the right way or there is any issue ? ---
