bigip_command – Run TMSH and BASH commands on F5 devices

New in version 2.4.

Synopsis

• Sends a TMSH or BASH command to an BIG-IP node and returns the results read from the device. This module includes an argument that will cause the module to wait for a specific condition before returning or timing out if the condition is not met.

• This module is not idempotent, nor will it ever be. It is intended as a stop-gap measure to satisfy automation requirements until such a time as a real module has been developed to configure in the way you need.

• If you are using this module, you should probably also be filing an issue to have a real module created for your needs.

Parameters

Parameter		Choices/Defaults	Comments
chdir string added in 2.6			Change into this directory before running the command.
commands raw / 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 integer		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 string		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.
provider dictionary added in 2.5			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.
	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.
	ssh_keyfile path		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 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: cli 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.
retries integer		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.
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.
wait_for list			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 boolean 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 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.
