module: apconos_command
author: "David Lee (@davidlee-ap)"
short_description: Run arbitrary commands on APCON devices
description:
- Sends arbitrary commands to an apcon device and returns the results
read from the device. The 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.
notes:
- Tested against apcon iis+ii
options:
commands:
description:
- List of commands to send to the remote device over the
configured provider. The resulting output from the command
is returned. If the I(wait_for) argument is provided, the
module is not returned until the condition is satisfied or
the number of retires as expired.
required: true
type: list
wait_for:
description:
- List of conditions to evaluate against the output of the
command. The task will wait for each condition to be true
before moving forward. If the conditional is not true
within the configured number of retries, the task fails.
See examples.
type: list
match:
description:
- The I(match) argument is used in conjunction with the
I(wait_for) argument to specify the match policy. Valid
values are C(all) or C(any). If the value is set to C(all)
then all conditionals in the wait_for must be satisfied. If
the value is set to C(any) then only one of the values must be
satisfied.
default: all
choices: ['any', 'all']
type: str
retries:
description:
- 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
I(wait_for) conditions.
default: 10
type: int
interval:
description:
- Configures the interval in seconds to wait between retries
of the command. If the command does not pass the specified
conditions, the interval indicates how long to wait before
trying the command again.
default: 1
type: int
