# ─── Fluksio docs site (zensical) ───
# Multi-stage: build the static documentation with zensical, serve it with Nginx.
# Routed to docs.${DOMAIN} by the `docs` service in compose.yml. The runtime
# image is just Nginx + static files (no Python), mirroring the SPA approach.

# ── Stage 1: Build the static site ───────────────────────────────
FROM python:3.13-slim AS docs-build
# Pin zensical so a rebuild is reproducible (it is only a build-time tool).
RUN pip install --no-cache-dir zensical==0.0.46

RUN zensical build --clean

# ── Stage 2: Serve static files ──────────────────────────────────
