short_description: Push configuration to OpenSwitch using declarative config
|
|
description:
|
|
- The OpenSwitch platform provides a library for pushing JSON structured
|
|
configuration files into the current running-config. This module
|
|
will read the current configuration from OpenSwitch and compare it
|
|
against a provided candidate configuration. If there are changes, the
|
|
candidate configuration is merged with the current configuration and
|
|
pushed into OpenSwitch
|

options:

|
src:
|
|
description:
|
|
- The path to the config source. The source can be either a
|
|
file with config or a template that will be merged during
|
|
runtime. By default the task will search for the source
|
|
file in role or playbook root folder in templates directory.
|
|
required: false
|
|
default: null
|
|
force:
|
|
description:
|
|
- The force argument instructs the module to not consider the
|
|
current devices running-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
|
|
include_defaults:
|
|
description:
|
|
- The module, by default, will collect the current device
|
|
running-config to use as a base for comparision to the commands
|
|
in I(src). Setting this value to true will cause the module
|
|
to issue the command `show running-config all` to include all
|
|
device settings.
|
|
required: false
|
|
default: false
|
|
choices: BOOLEANS
|
|
backup:
|
|
description:
|
|
- When this argument is configured true, the module will backup
|
|
the running-config from the node prior to making any changes.
|
|
The backup file will be written to backup_{{ hostname }} in
|
|
the root of the playbook directory.
|
|
required: false
|
|
default: false
|
|
choices: BOOLEANS
|
|
ignore_missing:
|
|
description:
|
|
- This flag instructs the module to ignore lines that are missing
|
|
from the device configuration. In some instances, the config
|
|
command doesn't show up in the running-config because it is the
|
|
default. See examples for how this is used.
|
|
required: false
|
|
default: false
|
|
choices: BOOLEANS
|
|
replace:
|
|
description:
|
|
- This argument will cause the provided configuration to be replaced
|
|
on the destination node. The use of the replace argument will
|
|
always cause the task to set changed to true and will implies
|
|
I(force) is true. This argument is only valid with I(transport)
|
|
is eapi.
|
|
required: false
|
|
default: false
|
|
choice: BOOLEANS
|
|
config:
|
|
description:
|
|
- The module, by default, will connect to the remote device and
|
|
retrieve the current running-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.
