I have deployed SeaweedFS stack into on-promises k8s cluster. The deployed instances are 1 master server, 1 volume server, 1 filer and S3 API gateway.
I defined k8s Deployment and Service on my own and I was able to make the stack running in the cluster. I am able to upload file using another NestJS backend that utilizes s3 API and filer API. The stack works correctly.
As they are not exposed via Ingress, I did port-forward of master, filer, s3 and volume server as follow for testing purpose.
I am able to access interface of master server via http://localhost:9333/, filer server via http://localhost:8888/ and s3 gateway via http://localhost:8333/. But I am not able to access volume server dashboard via http://localhost:8080/ui/index.html even though it is port-forwarded.
I still can get the metrics from volume server via port 9325, but port 8080 does not work.
Deployment and Service definitions for volume server look like this.

- After port-forward on mac,
lsof -i :8080command outputs nothing.
I tried to run the stack with the same configuration in docker-compose as follow, and I was able to access volume server dashboard via http://localhost:8080/ui/index.html.

I set different port for volume server than 8080, and exposed it via k8s Service accordingly, but after port-forward, I still cannot access the dashboard.
