# AWOOOI 第二個 Runner 安裝腳本
# =============================================================================
# 用途: 在 192.168.0.110 安裝第二個 self-hosted Runner (冗餘)
#
# 前置條件:
# 1. 先到 GitHub 獲取 Runner Token:
#    https://github.com/owenhytsai/awoooi/settings/actions/runners/new
#
# 執行方式:
#    ssh 192.168.0.110
#    RUNNER_TOKEN="<your-token>" bash setup-runner-2.sh
