# syntax=docker/dockerfile:1.6
# PUBLIC base image for GPU inference jobs (HF Jobs) — vLLM serving variant.
#
# Same contract as demo/image/Dockerfile: ONLY open-source, generic dependencies
# — NO proprietary code, and no names that reveal which models/techniques the
# pipeline uses. The Job's bootstrap (/opt/run-job.sh) pulls the private wheel +
# demo modules + the remaining runtime dependencies at startup and runs run_job.py.
#
# Built FROM vLLM's official OpenAI-server image rather than the llama.cpp
# CUDA-runtime base: vLLM's Triton JIT needs a CUDA build chain + a matched torch
# (gcc/ninja/nvcc are absent from the runtime base). torch therefore comes from the
# base and is omitted from the generated pyproject (JOB_IMAGE_BASE_PROVIDES=torch).
#
# Build: JOB_IMAGE_DIR=image-vllm JOB_IMAGE_BASE_PROVIDES=torch make demo-deploy-job
# (run-job.sh + the dataset_reviewer stub are shared from demo/image/.)

# Pinned (not :latest) so the serving CLI contract can't shift under a live demo run:
# vLLM 0.12 renamed the structured-outputs backend flag, and this repo's serve argv +
# fp8 flags target >=0.12. v0.19.1 validated on l40sx1 (boots fp8 + 6/6 valid structured
# JSON via the default auto backend, 2026-06-23) — bump deliberately, re-validating each.
FROM vllm/vllm-openai:v0.19.1

# The base image sets ENTRYPOINT to the OpenAI server; reset it so HF Jobs'
# `bash /opt/run-job.sh` (and the idle Space CMD) run as plain commands. The Job
# starts its own server as a co-located subprocess (demo/job/llm_server.py).
