2.1.2. Creating a physical node¶

Create a node

You need to create a node which you will assign to a pool.

You want to specify the values for user/pass and validate_certs only once but re-use them throughout your tasks. Use the bigip_node module.

1. Create a playbook node.yaml.

   • Type nano playbooks/node.yaml

   • Type the following into the playbooks/node.yaml file.

     ---
     
     - name: Create nodes and add to pool
       hosts: bigips
       connection: local
     
       vars:
         valid_certs: no
         username:  admin
         password: admin
         server: 10.1.1.245
     
       tasks:
           - name: Create node1
             bigip_node:
                 host: "10.1.20.11"
                 name: "10.1.20.11"
                 password: "{{ password }}"
                 server: "{{ server }}"
                 user: "{{ username }}"
                 validate_certs: "{{ valid_certs }}"
             delegate_to: localhost
     
           - name: Create node2
             bigip_node:
                 host: "10.1.20.12"
                 name: "10.1.20.12"
                 password: "{{ password }}"
                 server: "{{ server }}"
                 user: "{{ username }}"
                 validate_certs: "{{ valid_certs }}"
             delegate_to: localhost
     

   • Ctrl x to save file.

2. Run this playbook.

   • Type ansible-playbook playbooks/node.yaml

   If successful, you should see similar results

   

3. Verify BIG-IP results.

   • Select Local Traffic -> Nodes
