Root cause identified: - Volume server was using -ip=127.0.0.1 - Master couldn't reach volume server at 127.0.0.1 from its container - When Spark requested assignment, master tried to create volume via gRPC - Master's gRPC call to 127.0.0.1:18080 failed (reached itself, not volume server) - Result: 'No writable volumes' error Solution: - Change volume server to use -ip=seaweedfs-volume (container hostname) - Master can now reach volume server at seaweedfs-volume:18080 - Automatic volume creation works as designed - Kept -publicUrl=127.0.0.1:8080 for external clients (host network) Workflow changes: - Remove forced volume creation (curl POST to /vol/grow) - Volumes will be created automatically on first write request - Keep diagnostic output for troubleshooting - Simplified startup verification This matches how other SeaweedFS tests work with Docker networking.
