From 4ef110fd2c501b718344c72d495ad7e16d2bd465 Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Sat, 30 Dec 2023 23:25:20 +0100 Subject: T5474: establish common file name pattern for XML conf mode commands We will use _ as CLI level divider. The XML definition filename and also the Python helper should match the CLI node. Example: set interfaces ethernet -> interfaces_ethernet.xml.in set interfaces bond -> interfaces_bond.xml.in set service dhcp-server -> service_dhcp-server-xml.in --- src/conf_mode/service_salt-minion.py | 118 +++++++++++++++++++++++++++++++++++ 1 file changed, 118 insertions(+) create mode 100755 src/conf_mode/service_salt-minion.py (limited to 'src/conf_mode/service_salt-minion.py') diff --git a/src/conf_mode/service_salt-minion.py b/src/conf_mode/service_salt-minion.py new file mode 100755 index 000000000..a8fce8e01 --- /dev/null +++ b/src/conf_mode/service_salt-minion.py @@ -0,0 +1,118 @@ +#!/usr/bin/env python3 +# +# Copyright (C) 2018-2022 VyOS maintainers and contributors +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License version 2 or later as +# published by the Free Software Foundation. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
