              - { host: "{{ nd_ip2 }}" }
            when: state == "present"

          - name: Update a VS
            bigip_virtual_server:
              name: "{{ vs_name }}"
              pool: "{{ pl_name }}"
              state: "{{ state }}"

   - :guilabel:`Ctrl-x` to save file.

#. Run this playbook.

   - Type ``ansible-playbook -e @creds.yaml --ask-vault-pass playbooks/appseed.yaml``

#. Verify results in BIG-IP GUI.

   .. HINT:: You should see app3_vs deployed with 2 pool members.  App should
      be accessible on http://10.1.10.30.

#. Run this playbook to teardown app.

   - Type ``ansible-playbook -e @creds.yaml --ask-vault-pass playbooks/appseed.yaml -e state="absent"``

#. Verify that app3_vs, pool and nodes should be deleted in BIG-IP GUI.

   .. NOTE:: This playbook leverages a config seed file in 
      ``vars/appseedinfo.yaml``.  Simply modify this file to deploy a new
      service.
