# Deploy: pull latest git, rebuild images, recreate containers, apply SQL migrations.
# Run from the repo root (or anywhere — script cds to its directory).
#
# If you see: sudo: ./deploy.sh: command not found — make it executable: chmod +x deploy.sh
# Prefer running WITHOUT sudo: ./deploy.sh   (the script uses sudo for docker/git only when needed)
# Or: bash deploy.sh   or   sudo bash deploy.sh
#
# Usage:
#   ./deploy.sh                    # build, up, then apply supabase/migrations (tracked in DB)
#   ./deploy.sh migrate            # same as plain ./deploy.sh (kept for backwards compatibility)
#   FULL_REBUILD=1 ./deploy.sh    # docker compose build --no-cache
#   SKIP_MIGRATIONS=1 ./deploy.sh # skip node scripts/apply-sql-migrations.mjs (emergency / CI)
#
# Git “dubious ownership”: avoid sudo ./deploy.sh — it runs git as root while the clone is
# owned by your user. Prefer: ./deploy.sh as that user (default GIT_PULL_CMD is git pull, no sudo).
# Root-owned checkout only: GIT_PULL_CMD="sudo git pull --ff-only" ./deploy.sh
# Or one-time: git config --global --add safe.directory /path/to/clone
#
# Windows: use deploy.bat (optional: deploy.bat migrate, or deploy-with-migrate.bat).
#
# The compose stack is stopped (docker compose down) after pull and before build/up so old
# containers do not block port mappings or leave conflicting names. Set SKIP_STACK_STOP=1 to skip.
