# Install or upgrade chess-server (rc.d service `chessd`) with PostgreSQL
# inside a FreeBSD jail. Run as root inside the jail from a copy of this
# repository:
#
# 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
# CHESS_BINARY=/tmp/chess-server TRUSTED_PROXIES=<nginx-address> \
# 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
# Prerequisites:
# - postgresql18-server, postgresql18-client, and stockfish packages
# - the jail has its own System V shared memory (deploy/freebsd/host.sh)
# - the release binary, built with `make server-freebsd` (or `make server`
# on FreeBSD)
#
# Required:
# CHESS_BINARY new chess-server binary (FreeBSD/amd64, static)
# API_HOST address chess-server listens on (the jail IP)
# Inputs (environment):
# CHESS_BINARY required: chess-server binary to install
# TRUSTED_PROXIES address(es) the host nginx connects from, stored as
# chessd_trusted_proxies in rc.conf. Without it, every
# proxied client shares one rate-limit bucket.
# SPLIT_PRIVILEGES yes|no (default no); see deploy/postgresql/setup.sql
# ENABLE_LOG_ROTATION yes|no (default no): newsyslog entry for the log
# ENABLE_BACKUP yes|no (default no): nightly pg_dump via cron
#
# 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 service layout comes from rc.conf (chessd_*) with the defaults of
# deploy/freebsd/rc.d/chessd: account chess, home /home/chess, binary
# ~/bin/chess-server, log /var/log/chessd.log, 0.0.0.0:8080.
#
# 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 ->
# nightly backup -> start and health check
# Steps (idempotent; rerun to upgrade):
# 1. PostgreSQL: initdb only if no cluster exists; pg_hba.conf allows only
# postgres and chess over the Unix socket (peer); TCP listener disabled
# 2. role, database, and schema from deploy/postgresql/setup.sql (first run)
# 3. stop chessd; install the binary (previous kept as .prev) and the rc.d
# script (previous copy saved under /var/backups)
# 4. JWT key; schema migration; rc.conf settings
# 5. optional log rotation and backups
# 6. start chessd and check /health
# Files of a previous SQLite release are left untouched; remove them once the
# new release is verified.
