bigip_ucs_fetch – Fetches a UCS file from remote nodes

New in version 1.0.0.

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 Choices/Defaults Configuration Comments
async_timeout
integer
Default:
150
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.
backup
boolean
    Choices:
  • no ←
  • yes
Creates a backup file including the timestamp information so you can get the original file back if you overwrote it incorrectly.
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
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
    Choices:
  • no ←
  • yes
Make the module fail if the UCS file on the remote system is missing.
force
boolean
    Choices:
  • no
  • yes ←
If no, the file is only transferred if the destination does not exist.
only_create_file
boolean
added in 1.12.0
    Choices:
  • no ←
  • yes
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.
provider
dictionary
added in 1.0.0
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
    Choices:
  • no ←
  • yes
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.
password
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.

aliases: pass, pwd
server
string / required
The BIG-IP host.
You may omit this option by setting the environment variable F5_SERVER.
server_port
integer
Default:
443
The BIG-IP server port.
You may omit this option by setting the environment variable F5_SERVER_PORT.
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
    Choices:
  • rest ←
Configures the transport connection to use when connecting to the remote device.
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
    Choices:
  • no
  • yes ←
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.
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.
