Question

我有一个（powershell，如果重要的话）脚本，我希望为每个状态运行一次。这项工作在每个州花费的时间是可变的（不是基于州的人口或类似的事情，这是不可预测的），所以我想做的是创建一个以50个工作为步骤的流程，然后告诉Rundeck在5个线程中运行这50个作业。也许每个线程10个线程，但是可能不行，因为其中一些线程比其他线程更快。但是让Rundeck来管理它，所以如果在那个特定时间结束时是8-9-12-10-11，那就太好了。我了解如何使用Rundeck API创建这50个步骤并将其添加到工作流程中。

但是，我似乎看不到Rundeck如何完全按照我的意愿进行管理。工作流的策略似乎都假设您要在所有节点上运行所有作业（这意味着，如果我有50个步骤和5个节点，它将总共运行250件事，每个状态5次）-我不想要那个;我希望每个作业仅在一个节点上运行，但是我不在乎哪个节点是可用的任何节点。基本上，只是充当负载平衡器。

Rundeck是否支持此功能，还是我必须构建自己的负载平衡脚本？

Answer 1

我做了一个使用三个节点，三个作业和一个父作业的示例，以通过Job Reference Step将这三个作业分配给每个节点（一次）。

首先，使用并行策略调用子作业的父作业（意味着每个步骤（每个作业参考））同时运行，协调器作为一组节点的“随机子集”运行（在我的示例中为三个），将“计数”设置为“ 1”（每个作业参考步骤指向单个节点）。

          <uuid>e1ec6d2c-62d9-4de4-af6d-7e03f59cc4e5</uuid>
        </jobref>
      </command>
      <command>
        <jobref name='HelloWorldTWO' nodeStep='true'>
          <uuid>a57e74f2-050d-4a13-841a-3a4552d8227b</uuid>
        </jobref>
      </command>
      <command>
        <jobref name='HelloWorldTHREE' nodeStep='true'>
          <uuid>47067c03-da25-43e1-83cc-9fe0492f0797</uuid>
        </jobref>
      </command>
    </sequence>
    <uuid>17aad193-1e2c-45dc-b736-901c1de00954</uuid>
  </job>
</joblist>

现在，“子作业”将这些作业配置为指向一组具有随机子集编排器和“ 1”的节点，类似于“父作业”。

Here，您可以看到结果。

这也适用于步骤，作业参考步骤是命令步骤或脚本步骤之类的步骤。

并行运行作业池，每个作业仅执行一次
