public class ChildEntityCustomizer
extends BasicJcloudsLocationCustomizer

Location customizer that optionally creates and starts a child entity.

Use this class when the child entity should be created and started before the parent entity has begun executing its lifecycle methods. This is useful for supporting agent software installation or machine configuration tasks that are too complex to be defined in a singe pre.install.command script.

The CREATE_CHILD_ENTITY configuration key can be set to false to disable creation of the child entity.
