# syntax=docker/dockerfile:1.6
# PUBLIC base image for the cheap CPU ESTIMATE job (HF Jobs) — slim, no GPU stack.
#
# 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 at startup and runs run_job.py.
#
# This variant is CPU-ONLY and slim: it omits CUDA/torch and the GPU inference servers (the estimate
# runs zero signals and starts no model server — run_job.py returns at the ESTIMATE_ONLY branch
# before anything loads), and it omits an optional dependency group that `import dataset_reviewer`
# no longer pulls eagerly. Both shrink the image and its pull time, which is the bulk of the
# estimate's wall-clock. A lightweight tokenizer loads via the Rust `tokenizers` backend, so no
# torch is needed.
#
# Build: JOB_IMAGE_DIR=image-estimate JOB_IMAGE_BASE_PROVIDES=torch \
#        JOB_IMAGE_SPACE=<owner>/cpu-estimate-base make demo-deploy-job
# (run-job.sh + the dataset_reviewer stub are shared from demo/image/; the omitted dep group is
#  applied automatically for this variant — see demo/deploy_job.py.)
