Documentation preview: https://vllm--49020.org.readthedocs.build/en/49020/ |
docs/usage/security.md described a --grpc-port flag and a gRPC listener running on a separate TCP port alongside the HTTP server. The actual interface (added in vllm-project#36169) is a boolean --grpc flag on vllm serve that launches the gRPC server instead of the HTTP server, listening on the standard --host/--port address. Reworded the section to match, keeping all security guidance intact. docs/design/metrics.md misspelled --otlp-traces-endpoint as --oltp-traces-endpoint (the flag is otlp_traces_endpoint in vllm/config/observability.py).

Purpose
Two docs pages reference CLI flags that do not exist:
docs/usage/security.md(gRPC Interface section) says the service is enabled via a--grpc-portflag on a separate TCP port next to the HTTP server. The actual interface (added in feat(grpc): extract gRPC servicer into smg-grpc-servicer package, add --grpc flag to vllm serve #36169) is a boolean--grpcflag onvllm servethat launches the gRPC server instead of the HTTP one, listening on the standard--host/--portaddress (seevllm/entrypoints/openai/cli_args.pyand the early return invllm/entrypoints/cli/serve.py).docs/deployment/k8s.mdalready describes it correctly, so this brings security.md in line. All the security warnings and recommendations in the section are untouched, only the flag name and the architecture sentence changed.docs/design/metrics.mdspells the tracing flag--oltp-traces-endpoint. The config field isotlp_traces_endpoint(vllm/config/observability.py), OTLP as in OpenTelemetry Protocol, so anyone copying the flag from this page gets an argparse error.Found while auditing every
--flagmentioned indocs/against the current parsers. Checked for duplicates first: searched open PRs for grpc-port, oltp, and security.md; the open gRPC PRs (#42721, #48033, #36102) touch server code, none touch these doc lines.Test Plan
Docs-only change:
plus verifying the corrected flag names against source:
--grpcis defined invllm/entrypoints/openai/cli_args.pyandotlp_traces_endpointinvllm/config/observability.py. There is nogrpc_portoroltpanywhere invllm/.Test Result
All pre-commit hooks pass (markdownlint, typos, filename checks). Both corrected names resolve to real definitions in the source files above.
quick note: freshman here, still finding my feet in this codebase and trying to contribute for the greater good :) I traced the flags through the parsers myself and leaned on Claude Code for the audit script and to double check my reasoning. if I misread how the gRPC entrypoint works I would honestly love the correction.
