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.

Requirements ¶

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

f5-sdk >= 3.0.9

Parameters ¶

Parameter	Choices/Defaults	Comments
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. The commands argument also accepts an alternative form that allows for complex values that specify the command to run and the output format to return. This can be done on a command by command basis. The complex argument supports the keywords `command` and `output` where `command` is the command to run and `output` is 'text' or 'one-line'.
interval	Default: yes	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	Default: 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

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.

Return Values ¶

Common return values are documented here, the following are the fields unique to this module:

Key	Returned	Description
failed_conditions list	failed	The list of conditionals that have failed Sample: ['...', '...']
stdout list	always	The set of responses from the commands Sample: ['...', '...']
stdout_lines list	always	The value of stdout split into a list Sample: [['...', '...'], ['...'], ['...']]

Status ¶

This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
