Is there any way to set usable variable for task trigger in deployment.toml?

Question

as from my previous question i had to use environment variable to set interval for trigger in task , now i need to do same but instead of environment variable i need set same variable with same value in deployment.toml or elsewhere in my MI

i want set variable (i think it will be in deployment.toml) and use it as interval for my task trigger , so i will not need extra script to set environment variable on server where MI runs

You can't directly read variables from the deployment.toml OOB. But here is how you can do the same with a properties file.

1. Create a file named file.propertiesin MI_HOME/conf directory and add the following content

TASK_FREQUENCY=* * * * *

2. Now in your task you should be able to read this property like below.

<trigger cron="$FILE:TASK_FREQUENCY"/>

<?xml version="1.0" encoding="UTF-8"?>
<task class="org.apache.synapse.startup.tasks.MessageInjector" group="synapse.simple.quartz" name="TestTask" xmlns="http://ws.apache.org/ns/synapse">
    <trigger cron="$FILE:TASK_FREQUENCY"/>
    <property xmlns:task="http://www.wso2.org/products/wso2commons/tasks" name="injectTo" value="sequence"/>
    <property xmlns:task="http://www.wso2.org/products/wso2commons/tasks" name="message">
             <m0:getQuote xmlns:m0="http://services.samples">
                <m0:request>
                   <m0:symbol>IBM</m0:symbol>
                </m0:request>
             </m0:getQuote>
          </property>
    <property xmlns:task="http://www.wso2.org/products/wso2commons/tasks" name="sequenceName" value="SeqMy"/>
</task>
