it is possible to change credentials on several devices at the same time using automation tool?

Hi Alic

It is possible using Ansible or Python.

If you don't know Python, it might be quicker to do it using Ansible.

In Ansible, you define an inventory where you can add all of your 200 F5 BIG-IP hosts like this (replace bigip1 for the hostname that your bigips are reachable):

# inventory
bigip1
bigip2
bigip3
.
.
bigip200

Then you build your playbook with the single task of changing the password of all 200 BIG IPS (playbook.yaml file):

---
- hosts: all
  tasks:
  - name: Change the Admin password
    bigip_user:
      state: present
      username_credential: admin
      password_credential: <type your new password here>
      provider:
        server: "{{ inventory_hostname }}"
        user: admin
        password: <type your current password here>

Note: the inventory_hostname variable above will pick up the hostname you're connecting to from the inventory you defined.

Lastly you execute "ansible-playbook" command:

ansible-playbook -i inventory playbook.yaml

Hope it helps.

Cheers.
