New in version 2.4.

Synopsis

Requirements

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

  • f5-sdk >= 3.0.16

Parameters

Parameter Choices/Defaults Comments
chdir
(added in 2.6)
Change into this directory before running the command.
commands
required
The commands to send to the remote BIG-IP device over the configured provider. The resulting output from the command is returned. If the wait_for argument is provided, the module is not returned until the condition is satisfied or the number of retries as expired.
Only tmsh commands are supported. If you are piping or adding additional logic that is outside of tmsh (such as grep'ing, awk'ing or other shell related things that are not tmsh, this behavior is not supported.
interval Default:
1
Configures the interval in seconds to wait between retries of the command. If the command does not pass the specified conditional, the interval indicates how to long to wait before trying the command again.
match
    Choices:
  • any
  • all ←
The match argument is used in conjunction with the wait_for argument to specify the match policy. Valid values are all or any. If the value is set to all then all conditionals in the wait_for must be satisfied. If the value is set to any then only one of the values must be satisfied.
password
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
provider
(added in 2.5)
Default:
None
A dict object containing connection details.
ssh_keyfile
Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports.
You may omit this option by setting the environment variable ANSIBLE_NET_SSH_KEYFILE.
timeout Default:
10
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.
server
required
The BIG-IP host.
You may omit this option by setting the environment variable F5_SERVER.
user
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.
server_port Default:
443
The BIG-IP server port.
You may omit this option by setting the environment variable F5_SERVER_PORT.
password

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
validate_certs
bool
    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.
transport
required
    Choices:
  • rest
  • cli ←
Configures the transport connection to use when connecting to the remote device.
retries Default:
10
Specifies the number of retries a command should by tried before it is considered failed. The command is run on the target device every retry and evaluated against the wait_for conditionals.
server
required
The BIG-IP host.
You may omit this option by setting the environment variable F5_SERVER.
server_port
(added in 2.2)
Default:
443
The BIG-IP server port.
You may omit this option by setting the environment variable F5_SERVER_PORT.
transport
required

(added in 2.5)
    Choices:
  • rest ←
  • cli
Configures the transport connection to use when connecting to the remote device. The transport argument supports connectivity to the device over cli (ssh) or rest.
user
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
bool

(added in 2.0)
    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.
wait_for
Specifies what to evaluate from the output of the command and what conditionals to apply. This argument will cause the task to wait for a particular conditional to be true before moving forward. If the conditional is not true by the configured retries, the task fails. See examples.

aliases: waitfor
warn
bool

(added in 2.6)
    Choices:
  • no
  • yes ←
Whether the module should raise warnings related to command idempotency or not.
Note that the F5 Ansible developers specifically leave this on to make you aware that your usage of this module may be better served by official F5 Ansible modules. This module should always be used as a last resort.

Notes

Note

  • 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.
