Running a job on multiple nodes in parallel in Rundeck - rundeck

Question

Is there a possibility that a job can be run in parallel [it has only one task] on all the target nodes [15 nodes precisely]?
Also, will the Thread Count option in rundeck GUI solve the above purpose?
PS: I only have GUI access to Rundeck

Answer 1

You need to dispatch your job to your 15 nodes, and set ThreadCount = 15. I did an example with 3 nodes (node00,node01 and node02) to understand it:
<joblist>
<job>
<defaultTab>summary</defaultTab>
<description></description>
<dispatch>
<excludePrecedence>true</excludePrecedence>
<keepgoing>false</keepgoing>
<rankOrder>ascending</rankOrder>
<successOnEmptyNodeFilter>false</successOnEmptyNodeFilter>
<threadcount>3</threadcount>
</dispatch>
<executionEnabled>true</executionEnabled>
<id>c4a37a41-db35-4a76-b407-be6170c6502d</id>
<loglevel>INFO</loglevel>
<name>JobRemoteParallel</name>
<nodeFilterEditable>false</nodeFilterEditable>
<nodefilters>
<filter>node.*</filter>
</nodefilters>
<nodesSelectedByDefault>true</nodesSelectedByDefault>
<scheduleEnabled>true</scheduleEnabled>
<sequence keepgoing='false' strategy='node-first'>
<command>
<exec>sleep 2; echo "starting"</exec>
</command>
<command>
<exec>sleep 5; echo "processing"</exec>
</command>
<command>
<exec>echo "done!"</exec>
</command>
</sequence>
<uuid>c4a37a41-db35-4a76-b407-be6170c6502d</uuid>
</job>
</joblist>
Check how works.
