How to run multi module project in Spring boot - eclipse

Question

My maven project structure:
My question is, I need to run only parent module, that automatically instantiate that's sub modules(tomcat server). Is it possible with spring boot multi module project?
Note : I am using STS.
parent packaging is pom and child module packaging is jar files.
My Parent pom file
http://maven.apache.org/xsd/maven-4.0.0.xsd">
4.0.0
<groupId>com.test</groupId>
<artifactId>test-parent</artifactId>
<version>0.0.1-SNAPSHOT</version>

<relativePath /> <!-- lookup parent from repository -->
</parent>

My Question is how can I run parent project using tomcat? If I run parent project, child modules are automatically gets run or not?
Thanks in advance !!!

I have configured all the the microservices inside one docker-compose file. using docker-compose up command all modules gets started.(Make one microservice as service and others are child microservice)
