f5networks.f5_modules.bigip_data_group module – Manage data groups on a BIG-IP

Note

This module is part of the f5networks.f5_modules collection (version 1.20.0).

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_data_group.

New in f5networks.f5_modules 1.0.0

Synopsis

  • Allows for managing data groups on a BIG-IP. Data groups provide a way to store collections of values on a BIG-IP for later use in things such as LTM rules, iRules, and ASM policies.

Parameters

Parameter

Comments

delete_data_group_file

boolean

When yes, ensures the remote data group file is deleted.

This parameter is only relevant when state is absent and internal is no.

Choices:

  • false ← (default)

  • true

description

string

The description of the data group.

external_file_name

string

When creating a new data group, this specifies the file name you want to give an external data group file on the BIG-IP.

This parameter is ignored when internal is yes.

This parameter can be used to select an existing data group file to use with an existing external data group.

If this value is not provided, it will be given the value specified in name and, therefore, match the name of the data group.

This value may only contain letters, numbers, underscores, dashes, or a period.

internal

boolean

The type of this data group.

You should only consider setting this value in cases where you know exactly what you are doing, or, you are working with a pre-existing internal data group.

Be aware that if you deliberately force this parameter to yes, and you have a either a large number of records or a large total records size, this large amount of data will be reflected in your BIG-IP configuration. This can lead to long system configuration load times due to parsing and verifying the large configuration.

There is a limit of either 4 megabytes or 65,000 records (whichever is more restrictive) for uploads when this parameter is yes.

This value cannot be changed once the data group is created.

Choices:

  • false ← (default)

  • true

name

string / required

Specifies the name of the data group.

partition

string

Device partition to manage resources on.

Default: "Common"

provider

dictionary

added in f5networks.f5_modules 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

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:

  • false ← (default)

  • true

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:

  • false

  • true ← (default)

records

list / elements=any

Specifies the records you want to add to a data group.

If you have a large number of records, we recommend you use records_src instead of typing all those records here.

The technical limit of either the number of records, or the total size of all records. Varies with the size of the total resources on your system; in particular, RAM.

When internal is no, at least one record must be specified in either records or records_src.

When type is: ip, address, addr if the addresses use a non-default route domain, they must be explicit about it, meaning they must contain a route domain notation % e.g. 10.10.1.1%11. This is true regardless if the data group resides in a partition or not.

key

string / required

The key describing the record in the data group.

The key will be used for validation of the type parameter to this module.

value

any

The value of the key describing the record in the data group.

records_src

path

Path to a file with records in it.

The file should be well-formed. This means it includes records, one per line, that resemble the following format “key separator value”. For example, foo := bar.

BIG-IP is strict about this format, but this module is a bit more lax. It will allow you to include arbitrary amounts (including none) of empty space on either side of the separator. For an illustration of this, see the Examples section.

Record keys are limited in length to no more than 65520 characters.

Values of record keys are limited in length to no more than 65520 characters.

The total number of records you can have in your BIG-IP is limited by the memory of the BIG-IP itself.

The format of this content is slightly different depending on whether you specify a type of address, integer, or string. See the examples section for examples of the different types of payload formats that are expected in your data group file.

When internal is no, at least one record must be specified in either records or records_src.

separator

string

When specifying records_src, this is the string of characters that will be used to break apart entries in the records_src into key/value pairs.

By default, the value of this parameter is :=.

This value cannot be changed once it is set.

This parameter is only relevant when internal is no. It will be ignored otherwise.

Default: ":="

state

string

When state is present, ensures the data group exists.

When state is absent, ensures the data group is removed.

The use of state in this module refers to the entire data group, not its members.

Choices:

  • "present" ← (default)

  • "absent"

type

string

The type of records in this data group.

This parameter is important because it causes the BIG-IP to store your data in different ways to optimize access to it. For example, it would be wrong to specify a list of records containing IP addresses, but label them as a string type.

This value cannot be changed once the data group is created.

Choices:

  • "address"

  • "addr"

  • "ip"

  • "string" ← (default)

  • "integer"

  • "int"

Notes

Note

  • This module does NOT support atomic updates of data group members in a type internal data group.

  • Addition/Deletion of data group members in a type external data group should be done through Ansible modules only, if changes are made manually, the Ansible module will not detect those changes.

  • 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.
