[ansible-project] Group within another group issues

[William Muriithi]

Hello

I have an inventory set as follows:

[develop]
192.168.0.1 <- tomcat
192.168.0.2 <- tomcat
192.168.0.10 <- mysql Galera cluster
192.168.0.11 <- mysql Galera cluster
192.168.0.12 <- mysql Galera cluster

[qa]
192.168.1.1 <- tomcat
192.168.1.2 <- tomcat
192.168.1.10 <- mysql Galera cluster
192.168.1.11 <- mysql Galera cluster
192.168.1.12 <- mysql Galera cluster


Now, what I am trying to do is to set up tomcat database details
dynamically through host facts. Ansible can tell which system is a
mysql server and what is a tomcat server through custom facts. The IP
in the inventory are management IP (Used only to ssh in), all systems
do have a second payload interface (To which the iptables allow mysql
connections)

My question is, how would you go about extracting the payload IP
(Second interface) from the database systems so that ansible can plug
them in tomcat context.xml?

Regards,

William
