如何防止TeamCity生成AWS云代理实例

Question

当将TeamCity与一起使用时，它会无缘无故地每10分钟启动一次代理。

我正在使用代理来构建Yocto发行版，这需要大量的时间和资源。由于这个原因，代理运行在一个大型(昂贵)实例上，我只想在需要时启动该实例。

我想要做的是：

• 拥有一个运行TeamCity服务器的廉价AWS实例，始终处于打开状态。
• 拥有一个运行TeamCity代理的大型、昂贵的AWS实例，但只在需要时才打开。
• 只有在有生成要运行时，才能旋转代理机器。
• 当构建通过时，在git中放置一个标记。
• 最好是:检查服务器上是否有新的git提交，并在有提交时启动代理。

请注意，我想在代理上做标记，这样服务器端签出将无法工作(根据TeamCity文档)。

我在AWS中创建了一个安装程序，其中我有一个运行TeamCity服务器的小实例，以及一个运行代理的大型(昂贵)实例。在TeamCity中，我在根项目中配置了一个云配置文件，以便自动启动运行代理的机器，并在构建完成或机器闲置5分钟时停止它。启动和停止AWS机器工作，并触发构建als工作。

我创建了一个没有任何触发器的构建配置的项目。我还试图将git存储库的VCS根的最小检查间隔增加到90000000秒(这样它实际上就不会旋转代理机器)。

由于某些原因，TeamCity每10分钟启动一次运行代理的AWS实例，我不清楚它为什么要这样做。TeamCity日志显示：

(为保护无辜，已更改了实例id和代理名称)

即使没有配置触发器，我如何防止TeamCity服务器旋转代理计算机？当存在git提交时，启动代理计算机的最佳方法是什么？我正在考虑在一个更小的代理上构建一个单独的构建，它只检查提交，并使更大的构建依赖于这个较小的构建。

Answer 1

TeamCity中的日志记录显示“状态从停止到启动”，这让我认为是TeamCity启动了这个代理。结果是，运行构建代理的AWS实例是由OpsWorks启动的。

亚马逊的OpsWorks被配置为监视机器的状态并保持其“向上”。因此，当TeamCity正确关闭服务器时，OpsWorks会检测到机器正在停机，并试图再次启动它。过了一会儿，TeamCity检测到它是"up“和”空闲“，然后再次停止它。这件事一直在进行。

除了OpsWorks和VMWare特性之外，在TeamCity云配置中有一个EC2特性是很好的。这样，TeamCity就可以告诉Opsworks机器应该坏了。

目前，我们已经解决了这个问题，取消了OpsWorks健康监测的代理。

Answer 2

这不是正常的行为。逻辑是:如果没有现成的代理，Teamcity将启动一个云构建代理。如果空闲时，它将终止，这取决于您提供的选项。

我在根项目中创建了几个云概要文件。我使用以下选项：

• 附加终止条件/如果空闲，则在整个小时之前停止3分钟
• 最大实例计数:x

不确定这是否有帮助，但我没有任何“没有匹配到已停止的实例”条目，我可以在您的日志中看到。

另外-您是否尝试为云配置文件启用调试日志级别？您可以在Administration / Diagnostics (/admin/admin.html?item=诊断)中这样做。然后再次检查日志文件。
