# Local docker-compose overrides. Copy to .env (gitignored) for `docker compose
# up` / `make up` on a laptop:  cp .env.example .env
#
# Compose auto-reads a repo-root .env for ${VAR} interpolation in
# docker-compose.yml. On the fleet (dev/beta/prod), these values live in each
# environment's own rendered env file instead (/etc/thermograph.env,
# /etc/thermograph-beta.env — see deploy/secrets/README.md), so this file is
# only for a local, unmanaged run.

# Database password. Compose uses it to initialize the postgres container AND to
# build the app's THERMOGRAPH_DATABASE_URL. Change it before first `up`.
POSTGRES_PASSWORD=change-me

# OPTIONAL. Shared secret between the daemon service (Discord gateway + job
# timers) and the backend's /internal/* routes.
#
# Leave it empty and both ends DERIVE the same token from THERMOGRAPH_AUTH_SECRET
# (HMAC-SHA256 under a fixed label), which every environment already provisions —
# so the daemon needs no new vault entry and no operator step. Set it only to
# override that, e.g. to rotate this surface independently of the auth secret:
#   openssl rand -hex 32
#
# With neither this nor THERMOGRAPH_AUTH_SECRET set, both ends fail closed: the
# backend disables the internal routes and the daemon refuses to start. Never
# routed publicly — Caddy only forwards /api/*, /digest and
# /discord/interactions to the backend.
THERMOGRAPH_INTERNAL_TOKEN=

# --- Everything below is optional -- docker-compose.yml already defaults each
# --- of these, so a plain `make up` works with none of it set. Uncomment to
# --- override.

# TimescaleDB image tag. Defaults to the floating latest-pg18 tag. Pin it to an
# exact minor (e.g. 2.17.2-pg18) before any host of this stack could ever
# replicate with another -- see docker-compose.yml's db service comment.
# TIMESCALEDB_TAG=latest-pg18

# Postgres sizing. Only meaningful for an environment that runs its OWN db
# service — dev's compose stack (this file) and prod's Swarm stack, which
# sizes the ONE shared TimescaleDB instance on vps2 (see
# deploy/secrets/prod.yaml, currently DB_MEMORY=16g). Beta shares that same
# instance rather than running a second one, so a DB_MEMORY/DB_CPUS value in
# beta's own vault file no longer sizes anything — don't be misled by its
# presence there. Local/dev default to 8g / 2 CPUs.
# DB_MEMORY=8g
# DB_CPUS=2

# Backend uvicorn worker count and CPU cap. Terraform raises these on bigger
# hosts; defaults keep a plain `docker compose up` identical to before.
# WORKERS=4
# APP_CPUS=4

# Frontend CPU cap.
# FRONTEND_CPUS=2

# Registry + per-service image path/tag. Local dev normally builds each image
# in its own app repo (thermograph-backend / thermograph-frontend) tagged
# :local, which is the default here -- only set these to pull a specific
# published build instead of building locally.
