bigip_ucs_fetch – Fetches a UCS file from remote nodes

New in version 2.5.

Synopsis

  • This module is used for fetching UCS files from remote machines and storing them locally in a file tree, organized by hostname. Note that this module is written to transfer UCS files that might not be present, so a missing remote UCS won’t be an error unless fail_on_missing is set to ‘yes’.

Requirements

The below requirements are needed on the host that executes this module.

  • f5-sdk >= 3.0.16

Parameters

Parameter Choices/Defaults Comments
backup
boolean

create_on_missing
boolean
    Choices:
  • no
  • yes ←
Creates the UCS based on the value of src if the file does not already exist on the remote system.
dest

A directory to save the UCS file into.
encryption_password
-
Password to use to encrypt the UCS file if desired
fail_on_missing
boolean
    Choices:
  • no ←
  • yes
Make the module fail if the UCS file on the remote system is missing.

Notes

Note

  • BIG-IP provides no way to get a checksum of the UCS files on the system via any interface except, perhaps, logging in directly to the box (which would not support appliance mode). Therefore, the best this module can do is check for the existence of the file on disk; no check-summing.
  • For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.
  • Requires the f5-sdk Python package on the host. This is as easy as pip install f5-sdk.
  • Requires BIG-IP software version >= 12.
  • The F5 modules only manipulate the running configuration of the F5 product. To ensure that BIG-IP specific configuration persists to disk, be sure to include at least one task that uses the bigip_config module to save the running configuration. Refer to the module’s documentation for the correct usage of the module to save your running configuration.
