     ---
     
     - name: "Imperative: Deploy / teardown a web app (VS, pool, nodes)"
       hosts: bigips
       gather_facts: False
       connection: local
       vars_files:
         - ../vars/appseedinfo.yaml
     
     vars:
       state: "present"
     
     environment: "{{ bigip_env }}"
     
     tasks:
       - name: Adjust a VS
         bigip_virtual_server:
           name: "{{ vs_name }}"
           destination: "{{ vs_ip }}"
           port: "{{ vs_port }}"
           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/appseed.yaml

3. 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.

4. Run this playbook to teardown app.

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

5. 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.
