Automation with F5 LTM

Hello ALL, I'm working on a taks to get the configuration of a VIP and compare it with the VIP configuration on other LTM device.

 

Does the above task achievable through Ansible/python script?

 

Regards, Thiyagu

  • Ansible is more of a configuration tool using a declarative model which will not, to my knowledge, directly be able to compare but could be used to gather facts using the BIGIP Device Facts module to get information around

    Ansible bigip_device_facts – Collect facts from F5 BIG-IP devices

    For example can use the following in your Ansible playbook to get just the Virtual Server facts:

    - name: Collect BIG-IP Virtual Server facts
      bigip_device_facts:
        gather_subset:
          - virtual-servers
        provider:
          server: lb.mydomain.com
          user: admin
          password: secret
      delegate_to: localhost
    

    Once you have this can easily write this out to a file or even pass it to a Python script to locate the correct Virtual Server and compare configurations.

  • I have had some success approaching this slightly differently - I query the api of my "master" device and then use those values to set the configuration on my "slave" device with --check. This tells me what changes ansible would have made, so gives me an indication of the differences. Clunky, but has helped me out in a pinch
