In essence, launching a Vert.x application is not a complex task: write a class with a main method, create a Vert.x instance and deploy the main verticle.
But, very often, the same problems must be solved, for example:
-
configuring the number of verticle instances
-
deploying the main verticle as a worker verticle
-
creating a clustered Vert.x instance
-
properly closing Vert.x when the JVM is asked to stop via signals
The Vert.x application launcher is a tool which addresses such concerns, without repeating the same code in every project.
