Question

我正在启动ec2机器时运行用户数据脚本，该机器会在检查最后执行的命令的退出状态后关闭机器。我确认最后执行的命令已成功运行，因此我不确定为什么机器没有终止。并非每次都发生这种情况，似乎只有在用户数据脚本快速完成时才会发生。

这是我的bash脚本的结尾（在执行了几个命令之后）：

python myscript.py
ret=$?
echo $ret
if [[ $ret -eq 0 ]]; then
    shutdown now
fi

这将产生以下输出，但不会终止实例：

我正在尝试确定Cloud-init是否以某种方式阻止实例终止。是因为脚本在其他后台进程仍在初始化时完成了吗？

为什么当我使用“立即关闭”时，我的ec2实例有时不终止？
