Synopsis ¶

Sends an arbitrary 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.

Requirements ¶

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

f5-sdk >= 3.0.9

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 can omit this option if the environment variable `F5_PASSWORD` is set. aliases: pass, pwd
provider (added in 2.5)			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. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_SSH_KEYFILE` will be used instead.
	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 can omit this option if the environment variable `F5_SERVER` is set.
	user required		The username to connect to the BIG-IP with. This user must have administrative privileges on the device. You can omit this option if the environment variable `F5_USER` is set.
	server_port	Default: 443	The BIG-IP server port. You can omit this option if the environment variable `F5_SERVER_PORT` is set.
	password required		The password for the user account used to connect to the BIG-IP. You can omit this option if the environment variable `F5_PASSWORD` is set. aliases: pass, pwd
	validate_certs	Choices: no yes ←	If `no`, SSL certificates will not be validated. Use this only on personally controlled sites using self-signed certificates. You can omit this option if the environment variable `F5_VALIDATE_CERTS` is set.
	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 can omit this option if the environment variable `F5_SERVER` is set.
server_port (added in 2.2)		Default: 443	The BIG-IP server port. You can omit this option if the environment variable `F5_SERVER_PORT` is set.
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 can omit this option if the environment variable `F5_USER` is set.
validate_certs (added in 2.0)		Choices: no yes ←	If `no`, SSL certificates will not be validated. Use this only on personally controlled sites using self-signed certificates. You can omit this option if the environment variable `F5_VALIDATE_CERTS` is set.
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 (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.
