#
# PayloadCMS production image. Built and run by docker-compose.
#
# We use Next.js `output: 'standalone'` so the runtime stage doesn't have
# to ship the entire node_modules tree — Next analyses the code, picks
# only the files that are actually required at runtime, and bundles them
# under .next/standalone/. This sidesteps the pnpm content-addressable
# store / bin-link issues we hit with the workspace install.
#
# We install pnpm via `npm install -g pnpm@9` instead of corepack so
# the version negotiation is unambiguous across Node 20 minor releases.

FROM node:20-alpine AS base
RUN npm install -g pnpm@9
WORKDIR /repo

# ---- deps -----------------------------------------------------------------
# Install ALL workspace deps at the root so apps/cms can resolve its
# siblings (@payloadcms/*, next, react, etc.).

# ---- runtime --------------------------------------------------------------
# Compose the self-contained runtime image from the standalone output.
# - .next/standalone/  contains the server.js entrypoint and a trimmed
#   node_modules tree with only the files Next determined are needed.
# - .next/static/      is the hashed client-side bundles; standalone
#   does NOT include it, so we copy it over manually.
# - public/            static assets served from the web root (may be
#   absent; the COPY is guarded).
