# ─── BETE GitLab CI/CD Pipeline ───────────────────────────────────────────────
# Simply SSH into VPS → git pull → docker compose up -d --build
#
# Required CI/CD Variables (set in GitLab → Settings → CI/CD → Variables):
#
#   VPS_HOST        - VPS IP/hostname (e.g. 45.127.35.244)
#   VPS_USERNAME    - SSH user (e.g. root)
#   VPS_SSH_KEY     - SSH private key (type: file)
#
# Notes:
#   - VPS must have git access to this repo (deploy key or SSH agent)
#   - .env file must already exist on VPS at $APP_DIR/.env
#   - VPS_SSH_KEY must be "File" type so GitLab writes it to disk
#
