我们有两个应用程序需要很长时间（20 分钟到 7 天）才能完成数据处理和正确取消配置。我们仍然希望使用 Cloudformation 在 Autoscaling 组中管理它们。
问题是，如果我们想要缩减集群，我们需要能够告诉自动缩放终止特定实例并将集群的大小减小一。这在 Cloudformation 之外是可能的，但这会干扰使用 Cloudformation 更新自动缩放组的能力。
使用 Austoscaling Lifecyle Hooks 会很好，但它们最多等待 48 小时。
还有哪些其他选择？
是否可以使盐要求附加特定文件而不是仅存在的文件？
看来我只能要求一个file状态。源代码看起来像是从 require 属性中删除了任何方法名称。
在下面的示例中，我只希望 foo 服务在我的行已附加到 /etc/security/limits.conf 时运行。
file.append:
- name: /etc/security/limits.conf
- text:
- root hard nofile 65535
- root soft nofile 65535
foo:
service.running:
- enable: True
- require:
- file.append: /etc/security/limits.conf
我已经从 Ubuntu 12.04 上的 Puppet Labs APT 存储库安装了 puppet 3.1.1。我从 Puppet Forge 安装了 ploperations-puppet 模块来管理客户端系统上的 puppet 代理配置和包安装。我遇到了一些问题，所以我缩减了自己的编写，但仍然使用 ploperations-puppetlabs_apt 和 stahnma-puppetlabs_yum 模块来管理存储库。
对于以下测试，代理在主服务器上。
现在有了以下 site.pp
node default {
class { "puppetlabs_apt":
}
}
我收到以下错误：
# puppet agent --test

使用 ricardogarcia-helloworld 和 puppetlabs_yum 模块进行测试是成功的。此外，以下测试puppet apply成功（site.pp 与上面相同）：

我也尝试过使用include puppetlabs_apt代替课堂方式。
请问master为什么找不到这个模块，但是可以找到安装在同一位置的其他模块，还有什么办法呢？
我们有几台配备 iDrac Express 的戴尔服务器，我们想开始使用 iDrac 功能。我们的网络针对不同的子网分为几个 VLAN。我们的管理子网在 VLAN 28 上，我们的数据子网在 VLAN 29 上。我已将 iDrac express 设置为使用 VLAN 28。
如何配置交换机端口以不标记 VLAN 29 流量并接受标记有 VLAN 28 的流量？
