yeah, i just ran into what you're seeing with github actions not supporting different COMMANDs. i'm not familiar enough with the way that github actions work to know how to hit something running running as a container on the host from a container. i'd expect that

localhost:50051

within the node container would be only internal to the node container, and you'd need a hostname that would point to the host runner, and then the SpiceDB node would be available on port 50051 of whatever that hostname is.
