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 (on host that executes module)

  • f5-sdk >= 2.2.3

Options

parameter required default choices comments
commands
yes
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
no 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
no 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
yes
The password for the user account used to connect to the BIG-IP. This option can be omitted if the environment variable F5_PASSWORD is set.
retries
no 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
yes
The BIG-IP host. This option can be omitted if the environment variable F5_SERVER is set.
server_port
(added in 2.2)
no 443
The BIG-IP server port. This option can be omitted if the environment variable F5_SERVER_PORT is set.
user
yes
The username to connect to the BIG-IP with. This user must have administrative privileges on the device. This option can be omitted if the environment variable F5_USER is set.
validate_certs
(added in 2.0)
no True
  • True
  • False
If no, SSL certificates will not be validated. This should only be used on personally controlled sites using self-signed certificates. This option can be omitted if the environment variable F5_VALIDATE_CERTS is set.
wait_for
no
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
