Create a playbook called balance.yml as follows:
* The playbook contains a play that runs on hosts in balancers host group and uses
the balancer role.
--> This role configures a service to loadbalance webserver requests between hosts
in the webservers host group.curl
--> When implemented, browsing to hosts in the balancers host group (for example
http://node5.example.com) should produce the following output:
Welcome to node3.example.com on 192.168.10.z
--> Reloading the browser should return output from the alternate web server:
Welcome to node4.example.com on 192.168.10.a
* The playbook contains a play that runs on hosts in webservers host group and uses
the phphello role.
