1. Create a playbook seedapp.yaml.

   • Type nano playbooks/seedapp.yaml
   • Type the following into the playbooks/seedapp.yaml file.

   ---
   
   - name: "Create new web app"
     hosts: bigips
     gather_facts: False
     connection: local
     vars_files:
       - ../vars/{{ seed }}
   
     vars:
       state: "present"
       seed: "seed1.yaml"
   
     environment: "{{ bigip_env }}"
   
     tasks:
       - name: Adjust virtual server
         bigip_virtual_server:
           name: "{{ vs_name }}"
           destination: "{{ vs_ip }}"
           port: "{{ vs_port }}"
           description: "Web App"
           snat: "Automap"
           all_profiles:
             - "tcp-lan-optimized"
             - "http"
             - "analytics"
           state: "{{ state }}"
   
       - name: Adjust a pool
         bigip_pool:
           name: "{{ pl_name }}"
           monitors: "{{ pl_monitor }}"
           lb_method: "{{ pl_lb }}"
           state: "{{ state }}"
   
       - name: Add nodes
         bigip_node:
           name: "{{ item.name }}"
           host: "{{ item.host }}"
           state: "{{ state }}"
         loop:
           - { name: "{{ nd_ip1 }}", host: "{{ nd_ip1 }}" }
           - { name: "{{ nd_ip2 }}", host: "{{ nd_ip2 }}" }
   
       - name: Add nodes to pool
         bigip_pool_member:
           host: "{{ item.host }}"
           port: "{{ nd_port }}"
           pool: "{{ pl_name }}"
           state: "{{ state }}"
         loop:
           - { host: "{{ nd_ip1 }}" }
           - { host: "{{ nd_ip2 }}" }
         when: state == "present"
   
       - name: Update a VS
         bigip_virtual_server:
           name: "{{ vs_name }}"
           pool: "{{ pl_name }}"
           state: "{{ state }}"
         when: state == "present"
   

   • Ctrl x to save file.

2. Run this playbook.

   • Type ansible-playbook -e @creds.yaml --ask-vault-pass playbooks/seedapp.yaml

3. Verify results in BIG-IP GUI and browse to app.

   Hint

   You should see www12 deployed with 2 pool members. App should be accessible on http://10.1.10.12.

4. Run this playbook to teardown app.

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

5. Verify that www12, pool and nodes should be deleted in BIG-IP GUI.
