# ============================================

# XingRin Agent 启动脚本
|
||
# 用途：启动 agent 容器（心跳上报 + 负载监控）
|
||
#
|
||
# 架构说明：
|
||
# - 使用 docker run 直接启动 agent 容器
|
||
# - agent 负责心跳上报和系统负载监控
|
||
# - 扫描任务由主服务器通过 SSH 执行独立的 worker 容器
|
||
# - 镜像版本由主服务器传入，确保版本一致性
|
||
#
|
||
# 镜像拉取：
|
||
# - 使用 --pull=missing，优先使用本地镜像
|
||
# - 如果本地没有则从 Docker Hub 拉取
|
||
# ============================================
