Question

我想只在第一个节点发生故障时才在备用节点上执行作业。

备用节点表示第一个节点的副本。这是为了备份第一个节点，以防第一个节点出现故障或维护。

如何在rundeck上配置作业？

任何帮助表示赞赏。

Answer 1

据我所知，没有直接的方法，但您可以尝试使用API并使用任何首选语言进行编码。

1，在节点1上使用rundeck执行作业并获取执行ID。这里使用节点过滤器来选择第一个节点 2，检查该ID的执行状态 3，如果上述执行成功，你就会变得更好，不需要进一步。如果它失败，请执行第1步与第二个节点一起使用，并确保使用node filter方法选择第二个节点。

使用rundeck API执行作业执行示例

leo@leo-OptiPlex-3020:~$ curl -X POST -H "X-Rundeck-Auth-Token:************************" localhost:4440/api/1/job/949d9733-e55e-4bd2-9bc2-6a083807a363/run
<result success='true' apiversion='14'>
  <executions count='1'>
    <execution id='1154' href='http://localhost:4440/project/Testing/execution/show/1154' permalink='' status='running' project='Testing'>
      <user>admin</user>
      <date-started unixtime='1483966018421'>2017-01-09T12:46:58Z</date-started>
      <job id='949d9733-e55e-4bd2-9bc2-6a083807a363' averageDuration='2738' href='http://localhost:4440/api/14/job/949d9733-e55e-4bd2-9bc2-6a083807a363' permalink='http://localhost:4440/project/Testing/job/show/949d9733-e55e-4bd2-9bc2-6a083807a363'>
        <name>A</name>
        <group></group>
        <project>Testing</project>
        <description>A</description>
      </job>
      <description>#!/bin/bash
A=testA
echo $A [... 2 steps]</description>
      <argstring />
    </execution>
  </executions>
</result>leo@leo-OptiPlex-3020:~$

此处，执行ID为1154.要获取执行状态，

leo@leo-OptiPlex-3020:~$ curl -H "X-Rundeck-Auth-Token:*************************" localhost:4440/api/1/execution/1154
<result success='true' apiversion='14'>
  <executions count='1'>
    <execution id='1154' href='http://localhost:4440/project/Testing/execution/show/1154' permalink='' status='succeeded' project='Testing'>
      <user>admin</user>
      <date-started unixtime='1483966018000'>2017-01-09T12:46:58Z</date-started>
      <date-ended unixtime='1483966020000'>2017-01-09T12:47:00Z</date-ended>
      <job id='949d9733-e55e-4bd2-9bc2-6a083807a363' averageDuration='2766' href='http://localhost:4440/api/14/job/949d9733-e55e-4bd2-9bc2-6a083807a363' permalink='http://localhost:4440/project/Testing/job/show/949d9733-e55e-4bd2-9bc2-6a083807a363'>
        <name>A</name>
        <group></group>
        <project>Testing</project>
        <description>A</description>
      </job>
      <description>#!/bin/bash
A=testA
echo $A [... 2 steps]</description>
      <argstring />
      <successfulNodes>
        <node name='localhost' />
      </successfulNodes>
    </execution>
  </executions>
</result>leo@leo-OptiPlex-3020:~$

如果执行失败，您将收到状态失败的响应

leo@leo-OptiPlex-3020:~$ curl -H "X-Rundeck-Auth-Token:*******************" localhost:4440/api/1/execution/1155
<result success='true' apiversion='14'>
  <executions count='1'>
    <execution id='1155' href='http://localhost:4440/project/Testing/execution/show/1155' permalink='' status='failed' project='Testing'>
      <user>admin</user>
      <date-started unixtime='1483966084000'>2017-01-09T12:48:04Z</date-started>
      <date-ended unixtime='1483966086000'>2017-01-09T12:48:06Z</date-ended>
      <job id='949d9733-e55e-4bd2-9bc2-6a083807a363' averageDuration='2766' href='http://localhost:4440/api/14/job/949d9733-e55e-4bd2-9bc2-6a083807a363' permalink='http://localhost:4440/project/Testing/job/show/949d9733-e55e-4bd2-9bc2-6a083807a363'>
        <name>A</name>
        <group></group>
        <project>Testing</project>
        <description>A</description>
      </job>
      <description>#!/bin/bash
ls /sdbksncsklj</description>
      <argstring />
      <failedNodes>
        <node name='localhost' />
      </failedNodes>
    </execution>
  </executions>
</result>leo@leo-OptiPlex-3020:~$

仅当第一个节点失败时如何在备用节点上执行作业
