# Render Blueprint for the single Dockerized Streamlit service.
# https://render.com/docs/blueprint-spec
#
# Apply via the Render dashboard: New -> Blueprint -> point at this repo.
# (Everything here can also be set up manually in the dashboard instead --
# see README.md's "Deploying to Render" section for the exact manual
# equivalent of every value below.)

services:
  - type: web
    name: doa-demo
    runtime: docker
    dockerfilePath: ./Dockerfile
    plan: starter          # smallest paid plan with enough RAM for pyroomacoustics + numpy/scipy; adjust as needed
    region: oregon          # pick the region closest to your users
    branch: feature/real-world-benchmark-and-demo   # update to your default branch once merged

    # No httpPath health check is set -- Render's default TCP check
    # against $PORT is used instead. See README.md's "Health checks"
    # section for why this is the safer choice for a Streamlit service
    # (Streamlit's own optional /_stcore/health path is documented there
    # too, if a stricter HTTP check is ever wanted).

    envVars:
      - key: APP_DATA_DIR
        value: /var/data
      # PORT is injected automatically by Render -- do not set it here.

    # No persistent disk is attached. Everything under APP_DATA_DIR is
    # per-request scratch data (a temporarily-staged upload, a generated
    # .mat file consumed within the same request) that is deleted right
    # after use and never needs to survive a restart or be shared across
    # instances -- see README.md's "Storage & persistence" section.
    # If that ever changes (e.g. a feature that must persist data across
    # restarts), uncomment the block below and re-add a `disk:` reference
    # from this service. The literal /var/data path above is chosen
    # specifically so this can be enabled later without touching app
    # code.
    #
    # disk:
    #   name: doa-demo-data
    #   mountPath: /var/data
    #   sizeGB: 1
