f5networks.f5_modules.bigip_ucs_fetch module – Fetches a UCS file from remote nodes

Note

This module is part of the f5networks.f5_modules collection (version 1.17.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install f5networks.f5_modules.

To use it in a playbook, specify: f5networks.f5_modules.bigip_ucs_fetch.

New in version 1.0.0: of f5networks.f5_modules

Synopsis

• This module is used for fetching UCS files from remote machines and storing them locally in a file tree, organized by hostname. This module was written to create and transfer UCS files that might not be present, it does not require UCS file to be pre-created. So a missing remote UCS is not an error unless fail_on_missing is set to ‘yes’.

Parameters

Parameter	Comments
async_timeout integer	Parameter used when creating new UCS file on a device. The amount of time to wait for the API async interface to complete its task, in seconds. The accepted value range is between 150 and 1800 seconds. Default: 150
backup boolean	Creates a backup file including the timestamp information so you can get the original file back if you overwrote it incorrectly. Choices: no ← (default) yes
create_on_missing boolean	Creates the UCS based on the value of src, if the file does not already exist on the remote system. Choices: no yes ← (default)
dest path	A directory to save the UCS file into. This option is mandatory when only_create_file is set to no.
encryption_password string	Password to use to encrypt the UCS file if desired.
fail_on_missing boolean	Make the module fail if the UCS file on the remote system is missing. Choices: no ← (default) yes
force boolean	If no, the file is only transferred if the destination does not exist. Choices: no yes ← (default)
only_create_file boolean added in 1.12.0 of f5networks.f5_modules	If yes, the file is created on device and not downloaded. If the UCS archive exists on device, no change is made and file is not be downloaded. To recreate UCS files left on the device, remove them with bigip_ucs module before running this module with only_create_file set to yes. Choices: no ← (default) yes
provider dictionary added in 1.0.0 of f5networks.f5_modules	A dict object containing connection details.
auth_provider string	Configures the auth provider for to obtain authentication tokens from the remote device. This option is really used when working with BIG-IQ devices.
no_f5_teem boolean	If yes, TEEM telemetry data is not sent to F5. You may omit this option by setting the environment variable F5_TELEMETRY_OFF. Previously used variable F5_TEEM is deprecated as its name was confusing. Choices: no ← (default) yes
password aliases: pass, pwd string / required	The password for the user account used to connect to the BIG-IP. You may omit this option by setting the environment variable F5_PASSWORD.
server string / required	The BIG-IP host. You may omit this option by setting the environment variable F5_SERVER.
server_port integer	The BIG-IP server port. You may omit this option by setting the environment variable F5_SERVER_PORT. Default: 443
timeout integer	Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.
transport string	Configures the transport connection to use when connecting to the remote device. Choices: rest ← (default)
user string / required	The username to connect to the BIG-IP with. This user must have administrative privileges on the device. You may omit this option by setting the environment variable F5_USER.
validate_certs boolean	If no, SSL certificates are not validated. Use this only on personally controlled sites using self-signed certificates. You may omit this option by setting the environment variable F5_VALIDATE_CERTS. Choices: no yes ← (default)
src string	The name of the UCS file to create on the remote server for downloading. The file is retrieved or created in /var/local/ucs/. This option is mandatory when only_create_file is set to yes.

Notes

Note

• BIG-IP provides no way to get a checksum of the UCS files on the system via any interface with the possible exception of 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.

• If you are using this module with either Ansible Tower or Ansible AWX, you should be aware of how these Ansible products execute jobs in restricted environments. More information can be found here https://clouddocs.f5.com/products/orchestration/ansible/devel/usage/module-usage-with-tower.html

• Some longer running tasks might cause the REST interface on BIG-IP to time out, to avoid this adjust the timers as per this KB article https://support.f5.com/csp/article/K94602685

• For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.

• 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 f5networks.f5_modules.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.
