# deploy.sh — Remote deploy for Aether Platform
# Run on srv-nyx directly, or triggered via SSH from the workstation.
#
# Usage:   ./deploy.sh <prod|test> [app_branch] [api_branch]
# Example: ./deploy.sh prod
#          ./deploy.sh test ae_app_3x_llm development
#
# From workstation (npm run deploy:remote:prod / deploy:remote:test):
#   ssh linode.oneskyit.com 'bash /srv/env/prod_aether/deploy.sh prod'
#   ssh linode.oneskyit.com 'bash /srv/env/test_aether/deploy.sh test'
#
# NOTE: bak_aether shares the same app/api dirs as prod.
# After a prod deploy, restart bak containers manually if running:
#   cd /srv/env/bak_aether && docker compose restart ae_app ae_api
