# Base FrankenPHP image
FROM frankenphp_upstream AS frankenphp_base

WORKDIR /app

# NOTE: there is deliberately no `VOLUME /app/var/` here.
#
# It gave every container its own anonymous volume at /app/var, so attachments
# and raw messages written by the sync workers were invisible to the web
# container that serves them — downloads 404'd, and the data vanished on every
# container recreate. The durable paths are now bound explicitly per service
# (var/attachments, var/raw, var/uploads); see compose.override.yaml and
# truenas.compose.yaml. Re-adding this line silently breaks blob download again.

#
# From PGDG rather than Debian, and pinned to the same major as the server:
# pg_dump refuses outright to dump a server newer than itself, and Debian's
# postgresql-client trails 18 — so the distro package would install cleanly and
# then fail at the moment someone actually needed a backup.
#
# PGDG publishes amd64 and arm64, which the two-runner image build requires.

# /healthz, not Caddy's metrics port. The old probe answered as soon as the web
# server was listening, which is true well before PHP can reach the database —
# so a stack with an unreachable database reported itself healthy, and
# `depends_on: service_healthy` waited for nothing worth waiting for.
#
# The app endpoint returns 503 when the database is down and 200 otherwise; see
# App\Controller\HealthController for why a backed-up queue deliberately stays
# 200. The worker services have no HTTP server and disable this in compose —
# their liveness reaches the same endpoint through heartbeats instead.

# the source is copied in and .git stays behind. Left empty by a plain
# `docker build`, which is correct — an image nobody stamped honestly does not
# know what it is, and AppVersion says "development" rather than guessing.
# The release workflow passes both from the metadata action.
