# Deployment Scripts
Run in this order; each script's header documents its inputs. The full guide is
[doc/deployment.md](../doc/deployment.md).
| Order | Where | Script | Purpose |
|---|---|---|---|
| 1 | Bastille host | `freebsd/host.sh <jail>` | `sysvshm=new` for PostgreSQL, jail restart |
| 2 | Build machine | `make server-freebsd` | Static `bin/chess-server-freebsd-amd64` |
| 3 | Jail (root) | `freebsd/setup-jail.sh` | PostgreSQL 18, database, account, service, backups, optional SQLite import |
| 4 | Bastille host | `freebsd/nginx-chess.conf` | Location block for the host nginx |
Supporting files, installed by `setup-jail.sh`:
- `postgresql/setup.sql` — role, database, and schema (owner or split mode)
- `postgresql/migrate-sqlite.sh` — one-time import of a v0.11 SQLite database
- `freebsd/rc.d/chess_server` — `daemon(8)` service script
- `freebsd/chess-backup.sh` — nightly `pg_dump` with 14-day retention

#
# CHESS_BINARY=/tmp/chess-server-freebsd-amd64 \
# API_HOST=10.17.89.10 TRUSTED_PROXIES=10.17.89.1 \
# sh deploy/freebsd/setup-jail.sh
#
# Before the first run:
# 1. On the host: sh deploy/freebsd/host.sh <jail> (sysvshm=new, restart)
# 2. On a build machine: make server-freebsd, then copy
# bin/chess-server-freebsd-amd64 into the jail
# 3. For an existing SQLite deployment: note the database path; the old
# service is stopped before the import
#
# Required:
# CHESS_BINARY new chess-server binary (FreeBSD/amd64, static)
# API_HOST address chess-server listens on (the jail IP)
#
# Optional:
# API_PORT default 8080
# TRUSTED_PROXIES host nginx address(es) as seen from the jail; without it
# all proxied clients share one rate-limit bucket
# CHESS_HOME default: the chess account's home, else /usr/local/chess
# LOG_DIR default /var/log/chess
# SQLITE_DB v0.11 SQLite database to import once into an empty schema
# OLD_SERVICE rc.d name of the previous chess service to stop and
# disable (for example chess); skipped when unset
# SPLIT_PRIVILEGES yes: runtime role gets DML only, schema owned by
# chess_owner (default no; see deploy/postgresql/setup.sql)
# EXTRA_FLAGS additional chess-server flags (e.g. "-max-users 500")
# PGDATA default /var/db/postgres/data18
#
# The script is idempotent: rerun it to upgrade the binary, change flags, or
# repair configuration. It never drops data. Steps:
# packages -> PostgreSQL init and hardening -> role/database/schema ->
# chess account, binary, JWT key, log dir -> stop old service -> schema
# migration -> optional SQLite import -> rc.d/rc.conf -> log rotation ->

-- Provision the chess database on PostgreSQL 18. Run once as a superuser:
--
-- psql -X -U postgres -d postgres -f setup.sql # owner mode
-- psql -X -U postgres -d postgres -v split=true -f setup.sql # split mode
--
-- Owner mode (default): the login role `chess` owns schema `chess`, so the
-- server applies migrations itself at startup. It has no other privileges.
--
-- Split mode: NOLOGIN role `chess_owner` owns the schema and tables; the login
-- role `chess` receives only SELECT/INSERT/UPDATE/DELETE. The server starts
-- only when the schema is current; an administrator migrates, as the OS user
-- postgres, with
-- chess-server db init -dsn "dbname=chess user=postgres \
-- options='-c role=chess_owner -c search_path=chess'"
--
-- Neither mode sets a password: the chess OS user authenticates over the Unix
-- socket with peer authentication (see doc/deployment.md for pg_hba.conf).
