bigip_command - Run arbitrary command on F5 devices

New in version 2.4.

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:
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 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)
 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. 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
