如果一个节点成功，如何停止RunDeck作业在其他节点上运行

Question

我是 RunDeck 的新手，我有一个任务来创建一个在 4 个节点上运行的作业。 要求是在一个节点上运行此作业，如果成功则停止执行。如果作业失败则转到下一个节点。 最后，如果所有节点都失败，则将作业标记为失败，否则成功。

我使用了一个选项来在步骤失败时停止执行，但我没有找到任何选项来在步骤成功时停止执行。

你能帮我一下吗？

规则集策略（流程自动化的专有功能）是为这种场景而设计的，看看这个。

现在，在 Rundeck OSS 上您需要制作一些 script-fu。我做了一个需要两个作业的例子：一个是需要调度的作业，我们称之为“MyJob”，另一个是“执行器”作业，该作业以特定的逻辑执行第一个作业，并决定是否继续尝试是否下一个节点。

MyJob：这只是一个带有过滤器的简单作业。

- defaultTab: nodes
  description: ''
  executionEnabled: true
  id: 9fcc183b-b4df-4554-b75b-c660eda706b3
  loglevel: INFO
  name: MyJob
  nodeFilterEditable: false
  nodefilters:
    dispatch:
      excludePrecedence: true
      keepgoing: false
      rankOrder: ascending
      successOnEmptyNodeFilter: false
      threadcount: '1'
    filter: ${option.thenode}
  nodesSelectedByDefault: true
  options:
  - name: thenode
  plugins:
    ExecutionLifecycle: {}
  scheduleEnabled: true
  sequence:
    commands:
    - exec: cat file
    keepgoing: true
    strategy: node-first
  uuid: 9fcc183b-b4df-4554-b75b-c660eda706b3

执行器作业：执行具有特定行为的第一个作业：在一个特定节点中发现成功执行后，停止在其余节点上执行。

- defaultTab: nodes
  description: ''

如果您需要看看“失业”，这里是脚本

#!/bin/bash

    # script that detects only when all nodes fail
    # based on the following answer:
    # https://stackoverflow.com/questions/58798856/rundeck-fail-a-job-only-when-all-nodes-fail

    for currentnode in $(echo $mynodes | sed "s/,/ /g"); do
        if [ "$flag" -gt 0 ]; then
            echo "the job has been succeeded in $currentnode"
            exit 0
        else
            sleep $pt
            execid=$(curl -s -H accept:application/json --data-urlencode "argString=-thenode $currentnode" http://$server:$port/api/$api/job/$jobid/run?authtoken=$token | jq -r '.id')

            sleep  $pt
            status=$(curl -s --location --request GET "http://$server:$port/api/$api/execution/$execid/state?authtoken=$token" | jq -r '.executionState')

            # if job runs OK, then assign the value 1 to flag
            if [ "$status" = "SUCCEEDED" ]; then
                flag=1
            fi
        fi
    done

逻辑是委托脚本步骤中的行为。
