module: ordnance_config
author: "Alexander Turner (@alexanderturner) <alex.turner@ordnance.io>"
short_description: Manage Ordnance configuration sections
description:
- Ordnance router configurations use a simple block indent file syntax
for segmenting configuration into sections. This module provides
an implementation for working with these configuration sections in
a deterministic way.
options:
lines:
description:
- The ordered set of commands that should be configured in the
section. The commands must be the exact same commands as found
in the device running-config. Be sure to note the configuration
command syntax as some commands are automatically modified by the
device config parser.
aliases: ['commands']
parents:
description:
- The ordered set of parents that uniquely identify the section or hierarchy
the commands should be checked against. If the parents argument
is omitted, the commands are checked against the set of top
level or global commands.
src:
description:
- Specifies the source path to the file that contains the configuration
or configuration template to load. The path to the source file can
either be the full path on the Ansible control host or a relative
path from the playbook or role root directory. This argument is mutually
exclusive with I(lines), I(parents).
before:
description:
- The ordered set of commands to push on to the command stack if
a change needs to be made. This allows the playbook designer
the opportunity to perform configuration commands prior to pushing
any changes without affecting how the set of commands are matched
against the system.
after:
description:
- The ordered set of commands to append to the end of the command
stack if a change needs to be made. Just like with I(before) this
allows the playbook designer to append a set of commands to be
executed after the command set.
match:
description:
- Instructs the module on the way to perform the matching of
the set of commands against the current device config. If
match is set to I(line), commands are matched line by line. If
match is set to I(strict), command lines are matched with respect
to position. If match is set to I(exact), command lines
must be an equal match. Finally, if match is set to I(none), the
module will not attempt to compare the source configuration with
the running configuration on the remote device.
default: line
choices: ['line', 'strict', 'exact', 'none']
replace:
description:
- Instructs the module on the way to perform the configuration
on the device. If the replace argument is set to I(line) then
the modified lines are pushed to the device in configuration
mode. If the replace argument is set to I(block) then the entire
command block is pushed to the device in configuration mode if any
line is not correct.
default: line
choices: ['line', 'block']
multiline_delimiter:
description:
- This argument is used when pushing a multiline configuration
element to the Ordnance router. It specifies the character to use
as the delimiting character. This only applies to the
configuration action
default: "@"
backup:
description:
- This argument will cause the module to create a full backup of
the current C(running-config) from the remote device before any
changes are made. The backup file is written to the C(backup)
folder in the playbook root directory. If the directory does not
exist, it is created.
type: bool
default: 'no'
config:
description:
- The C(config) argument allows the playbook designer to supply
the base configuration to be used to validate configuration
changes necessary. If this argument is provided, the module
will not download the running-config from the remote node.
defaults:
description:
- This argument specifies whether or not to collect all defaults
when getting the remote device running config. When enabled,
the module will get the current config by issuing the command
C(show running-config all).
type: bool
default: 'no'
save:
description:
- The C(save) argument instructs the module to save the running-
config to the startup-config at the conclusion of the module
running. If check mode is specified, this argument is ignored.
type: bool
default: 'no'
