Edit / Develop JBOSS EAP Ansible playbook per my Red Hat Linux env

I would like to tear down and build up Red Hat Linux 7 JBOSS EAP at will using Ansible. I have a playbook but need it modified to fit certain requirements. IE install Domain Controller, Install and register clients using JBOSS 7.1 installer zip file. Create Self Signed Certificates, update vault password, install into a defined directory, grab from static system location, etc. The downloaded playbook does most of this already. Give me complete instructions on the changes and usage. The playbook is attached with yamal files. I can give you Jboss 7.1.0 installer if needed for your testing.
