Dig deeper into Ansible and F5 integration

So If I get this correctly you want to run a playbook on multiple virtual servers and each virtual server has multiple irules

See if this works for you

Variable file

virtualserver:
 - name: Test1
   ip: "10.192.xx.xx"
   irules:
   - irule1
   - irule2
 - name: Test2
   ip: "10.192.xx.xx"
   irules:
   - irule1
   - irule3

Playbook task:

- name: Add VS on BIG-IP
    bigip_virtual_server:
       server: "10.192.xx.xx"
       user: "****"
       password: "****"
       name: "{{item.name}}"
       destination: "{{item.ip}}"
       port: 80
       irules: "{{item.irules}}"
       validate_certs: False
    with_items: "{{virtualserver}}"
    delegate_to: localhost

Result:

changed:  => (item={u'irules': [u'irule1', u'irule2'], u'ip': u'10.192.xx.xx', u'name': u'Test1'})
changed:  => (item={u'irules': [u'irule1', u'irule3'], u'ip': u'10.192.xx.xx', u'name': u'Test2'})
