Go to step based on variable

[Andrea Favero]

Hello, I have this simple question:

As step 1, i have a shell script which performs some operations and outputs a variable at the end.

If the variable equals = foo, I want the job to continue from step 2.

If the variable equals = bar, I want the job to continue from step 3 (skipping step 2).

If the variable equals = baz, I want the job end with "success".

Is this possibile to achieve without Rundeck's pro workflow strategy?

Thanks!

Andrea

Hi Andrea,

A good way to do that is to use data variables (data passing) that can be caught by any step (and decide if that step is executable or not, as you see, it's basically scripting).

I leave an example that works as you want:

<joblist>
  <job>
    <context>
      <options preserveOrder='true'>
        <option enforcedvalues='true' name='variable' values='foo,bar,baz' valuesListDelimiter=',' />
      </options>
    </context>
    <defaultTab>nodes</defaultTab>
    <description></description>
    <executionEnabled>true</executionEnabled>
    <id>7091b22a-5e87-40ad-8728-5477ccd68646</id>
    <loglevel>INFO</loglevel>
    <name>JobEXAMPLE</name>
    <nodeFilterEditable>false</nodeFilterEditable>
    <scheduleEnabled>true</scheduleEnabled>
    <sequence keepgoing='false' strategy='sequential'>
      <command>
        <plugins>
          <LogFilter type='key-value-data'>
            <config>
              <logData>true</logData>
              <regex>^(VARIABLE)\s*=\s*(.+)$</regex>
            </config>
          </LogFilter>
        </plugins>
        <script><![CDATA[echo "VARIABLE=@option.variable@"]]></script>
        <scriptargs />
      </command>
      <command>
        <script><![CDATA[if [ @data.VARIABLE@ = "foo" ]
then
    echo "doing the step two."
fi]]></script>
        <scriptargs />
      </command>
      <command>
        <script><![CDATA[if [ @data.VARIABLE@ = "bar" ]
then
    echo "skipping step two, doing the step three"
fi]]></script>
        <scriptargs />
      </command>
      <command>
        <script><![CDATA[if [ @data.VARIABLE@ = "baz" ]
then
    echo "job success"
fi]]></script>
        <scriptargs />
      </command>
    </sequence>
    <uuid>7091b22a-5e87-40ad-8728-5477ccd68646</uuid>
  </job>
</joblist>

You have a good starting point about data passing here:

Hope it helps!

Hello Reiner, thank you for your reply.

Yes, I did setup something similar, and this is what I've came up with:

if [ @data.test@ = "true" ]
then
    echo "doing the step three."
    /home/test/script_test_3.sh
fi

This works indeed correctly if I want all the scripts dispatched to the same node.

But what if the first script is on node A and the script inside the if condition ( /home/test/script_test_3.sh  in my example ) is in node B ?

Is this possible?

Thank you!

Hi Andrea,

In this case you need to use Job Reference Step to some job pointing to a specific node (the nodes works on project level). Another way is to use a command to execute in that remote node in your step like this:

Thank you very much!! :)
