# LAN-dev deploy: roll the per-service registry-pull stack (see deploy.sh) onto
# the ~/thermograph-dev overlay instead of prod/beta's loopback-only stack.
#
# This script assumes $APP_DIR is a checkout of the monorepo (deploy assets under infra/),
# the same way /opt/thermograph is on prod/beta. That is the live state: the LAN
# box's ~/thermograph-dev was reprovisioned as an infra checkout during the
# 2026-07-22 cutover (the app monorepo is archived), provision-dev-lan.sh's
# REPO_URL defaults to this repo, and the app repos' deploy-dev.yml workflows
# invoke this script on the thermograph-lan runner. This IS the live LAN-dev
# deploy path.
#
# Design: a thin wrapper around deploy.sh, not a duplicate. deploy.sh already owns
# the entire per-service registry-pull mechanism -- secrets sourcing, docker login,
# the retry-pull loop, --no-deps single-service rolls vs. --remove-orphans `all`,
# .image-tags.env persistence, and the 8137/8080 health checks. None of that is
# dev-specific; the only things LAN dev actually changes are WHERE it deploys
# (a separate checkout + branch) and WHICH compose files are in play (the base
# file plus docker-compose.dev.yml's uncapped/LAN-published overrides). Both are
# expressible as environment (APP_DIR/BRANCH that deploy.sh already reads, and
# docker compose's own COMPOSE_FILE variable), so re-exec'ing deploy.sh with that
# environment set covers it with no forked copy of the pull/roll/health logic to
# drift out of sync. If LAN dev ever needs deploy logic that genuinely diverges
# from prod/beta (not just "different files/directory"), promote this to a
# standalone script at that point rather than growing special cases into deploy.sh.
#
# Usage, mirrors deploy.sh directly:
#   # roll just the backend onto a dev-tagged image:
#   ssh dev-box 'SERVICE=backend BACKEND_IMAGE_TAG=sha-<12hex> deploy/deploy-dev.sh'
#   # bring the whole dev stack up (both tags required, same as deploy.sh):
#   ssh dev-box 'SERVICE=all BACKEND_IMAGE_TAG=sha-<a> FRONTEND_IMAGE_TAG=sha-<b> deploy/deploy-dev.sh'

# --- Secrets -----------------------------------------------------------------
# dev renders from the SOPS vault the same way prod and beta do -- same files, same
# tool, same edit/commit/deploy loop -- with two dev-only adjustments. Both are
# expressed as environment that render-secrets.sh already parameterises, so nothing
# about the rendering logic is forked. See deploy/secrets/README.md.

# (1) dev renders deploy/secrets/dev.yaml ALONE; it does NOT layer common.yaml.
#
# common.yaml is the internet-facing fleet's SHARED PRODUCTION credential set: the
# registry token, both S3 keypairs (the bucket keypair is read-write, and that
# bucket also holds prod's database backups), the VAPID private key that signs push
# to real subscribers, the IndexNow key, the metrics token. Layering it here would
# write all of them in plaintext to /etc/thermograph.env on the box that is also the
# Forgejo CI runner, and hand them to every container in the dev stack through
# `env_file:` -- that is, to whatever unreviewed branch dev happens to be running.
# It would also silently apply THERMOGRAPH_COOKIE_SECURE=1, which is correct for the
# TLS hosts and breaks login on dev's plain-HTTP LAN URL.
#
# dev.yaml is self-contained instead: it carries dev's own copy of everything dev
# genuinely needs, and nothing else.
export THERMOGRAPH_SECRETS_SKIP_COMMON=1

# (2) The age key is read from wherever it is READABLE, not necessarily
# /etc/thermograph/age.key. render-secrets.sh falls back to `sudo cat` for a
# root-owned 0400 key, and this box has no passwordless sudo -- under the Forgejo
# runner (a systemd --user service, no tty) that sudo cannot prompt, so the
# fleet-standard placement would make every dev deploy fail at the render. Prefer
# the standard path when it is readable; otherwise the operator's own keyring, which
# is where dev's key already lives (this box is the machine `sops` is run on), so
# provisioning dev needs no second copy of the estate's recovery root.

# Fail closed rather than leak. If this box is provisioned to render (an env marker
# AND a key) but the render-secrets.sh in this checkout predates
# THERMOGRAPH_SECRETS_SKIP_COMMON, the render would quietly concatenate common.yaml
# into dev's /etc/thermograph.env -- exactly the leak (1) exists to prevent, with a
# success exit code. Checking a sibling script for the flag is blunt, but the two
# files are versioned together in this same checkout, and the alternative failure
# mode is unreviewed code running with the estate's object-storage keys. Remove this
# once the flag is unconditionally present in render-secrets.sh.

# deploy.sh needs POSTGRES_PASSWORD to interpolate the compose file (both to init the

# box it arrives from dev.yaml via the render above -- deploy.sh sources
# /etc/thermograph.env AFTER calling the renderer, so the vault value wins over this
# line. This default is the fallback for the un-vaulted paths that remain: a fresh
# box before provisioning, and a bare `make dev-up`. It is the same value dev.yaml
# holds and the value dev's existing pgdata volume was initialized with -- keep the
# two in step, and note that changing it needs an ALTER ROLE against the running
# database as well (see deploy/secrets/README.md), not just an edit.

# and has no default here. dev pulls with the persistent `docker login` credential
# already in this host's docker config -- the same arrangement the prod/beta CI
# deploy paths use, and the reason deploy.sh's login step is conditional. Putting a
# registry token in dev's vault would only add a second copy of a credential the box
# already has, in a file more processes can read. Export it by hand for a one-off run
# on a box that has never logged in; a genuine auth problem fails loudly at `pull`.
