Example Playbook and Setup in F5 Imperative Collection¶
Follow this tutorial to create a pool, add two members to that pool, and assign a virtual server to serve requests to the members in the pool.
You can create your own yaml file to use as a playbook, or follow along with this yaml file.
Creating an inventory file¶
All Ansible work starts with an inventory file.
For the purposes of this tutorial, it is not necessary to have anything special in the inventory file because we will be specifying our BIG-IP connection information within the playbook itself.
If you want to see more thorough examples of inventory in Ansible, we recommend you refer to inventory documentation found on Ansible’s website.
Let’s put the following text in a new file located at inventory/hosts.
localhost
The Playbook¶
Create a file called playbook.yaml in your current working directory and place the following content within it.
---
- name: Create a VIP, pool and pool members
hosts: all
connection: local
vars:
provider:
password: admin
server: 1.1.1.1
user: admin
validate_certs: no
server_port: 443
tasks:
- name: Create a pool
bigip_pool:
provider: "{{ provider }}"
lb_method: ratio-member
name: web
slow_ramp_time: 120
delegate_to: localhost
- name: Add members to pool
bigip_pool_member:
provider: "{{ provider }}"
description: "webserver {{ item.name }}"
host: "{{ item.host }}"
name: "{{ item.name }}"
pool: web
port: 80
with_items:
- host: 10.10.10.10
name: web01
- host: 10.10.10.20
name: web02
delegate_to: localhost
- name: Create a VIP
bigip_virtual_server:
provider: "{{ provider }}"
description: foo-vip
destination: 172.16.10.108
name: vip-1
pool: web
port: 80
snat: Automap
profiles:
- http
- clientssl
delegate_to: localhost
Run the playbook¶
We can now run our playbook. We will run this from the top-level ansible directory.
Refer to the command below.
ansible-playbook -i inventory/hosts playbook.yaml
If you followed the above steps correctly, you should see output similar to what is shown below.
PLAY [Create a VIP, pool and pool members] ***********************************************
TASK [Gathering Facts] *******************************************************************
