# Dev deploy: roll the per-service registry-pull stack (see deploy.sh) onto the
# dev compose overlay instead of beta/prod's Swarm stacks.
#
# Dev lives on vps1 now, at /opt/thermograph-dev — not on the operator's desktop.
# The desktop hosts no Thermograph environment any more; it runs the AI models
# and offers flex Swarm capacity. What moved is only WHERE and HOW dev is
# reached: it is a normal fleet host now (SSH deploy from CI, SOPS render at
# /etc/thermograph.env, mesh-only exposure on 10.10.0.2:8137), rather than a
# sudo-free systemd --user stack on someone's Wi-Fi.
#
# $APP_DIR is a checkout of the monorepo (deploy assets under infra/), the same
# way /opt/thermograph is for prod. A laptop can still point APP_DIR at a
# checkout under $HOME and get the old local behaviour.
#
# 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 dev actually changes are WHERE it deploys (a
# separate checkout + branch), WHICH compose files are in play (the base file
# plus docker-compose.dev.yml's uncapped/mesh-published overrides), and its
# secrets policy (below). All 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 dev ever
# needs deploy logic that genuinely diverges from beta/prod (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 vps1 'SERVICE=backend BACKEND_IMAGE_TAG=sha-<12hex> /opt/thermograph-dev/infra/deploy/deploy-dev.sh'
#   # bring the whole dev stack up (both tags required, same as deploy.sh):
#   ssh vps1 'SERVICE=all BACKEND_IMAGE_TAG=sha-<a> FRONTEND_IMAGE_TAG=sha-<b> /opt/thermograph-dev/infra/deploy/deploy-dev.sh'

# Dev context: its own checkout and its own branch, on its own host (vps1).

# 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

# (1b) Snap-packaged Docker is confined to $HOME (plus a short allowlist) and
# silently can't see /etc/thermograph.env at all, so env_file: /etc/thermograph.env
# resolves to nothing for every container no matter how correctly it's rendered.
# Where that is the case, mirror the render to a path under $APP_DIR;
# docker-compose.dev.yml carries a matching optional env_file entry.
#
# CONDITIONAL, not unconditional: this writes a plaintext copy of the render
# into the checkout, and on vps1 (ordinary apt Docker, which reads /etc fine)
# that copy would be pure liability. Detect the confinement rather than add a
# knob someone has to remember — the docker binary resolving under /snap is
# exactly the condition that breaks the /etc path.

# (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, which needs passwordless sudo.
#
# On vps1 that is the normal case: the `agent` user has passwordless sudo and
# the key sits at the fleet-standard path, so this block does nothing. The
# fallback exists for the laptop case — a checkout where the key lives only in
# the operator's own keyring (that machine is where `sops` is run), and where a
# non-interactive shell could not prompt for sudo even if the key were in /etc.
# Preferring the standard path when readable keeps vps1 on the fleet convention
# and means provisioning dev needs no second copy of the estate's recovery root.

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

# 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
