module: junos_config
version_added: "2.1"
author: "Peter sprygada (@privateip)"
short_description: Manage Juniper JUNOS configuration sections
description:
- This module provides an implementation for configuring Juniper
JUNOS devices. The configuration statements must start with either
`set` or `delete` and are compared against the current device
configuration and only changes are pushed to the device.
extends_documentation_fragment: junos
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 config. Be sure to note the configuration
command syntanx as some commands are automatically modified by the
device config parser.
required: true
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
required: false
default: null
after:
description:
- The ordered set of commands to append to the end of the command
stack if a changed 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.
required: false
default: null
force:
description:
- The force argument instructs the module to not consider the
current device config. When set to true, this will cause the
module to push the contents of I(src) into the device without
first checking if already configured.
required: false
default: false
choices: BOOLEANS
config:
description:
- The module, by default, will connect to the remote device and
retrieve the current config to use as a base for comparing
against the contents of source. There are times when it is not
desirable to have the task get the current running-config for
every task in a playbook. The I(config) argument allows the
implementer to pass in the configuruation to use as the base
config for comparision.
required: false
default: null
