deploy.sh

Rama main · réplica de lectura del repositorio original.

#!/usr/bin/env bash
# deploy.sh — Deploys this repo to a remote Docker host over SSH.
#
# Reads HOST and SUDO_PASS from .env.deploy (gitignored). Example .env.deploy:
#   HOST=user@1.2.3.4
#   REMOTE_DIR=/home/user/patzer
#   SUDO_PASS=...
#   HOST_PORT=8800
#
# Usage:
#   ./deploy.sh              # tar source → ssh, build & start
#   ./deploy.sh --no-build   # restart without rebuilding the image
#   ./deploy.sh --logs       # tail logs after deploy
