From 277a2b5df14c78db8e494d366800bbf9eb4c8e50 Mon Sep 17 00:00:00 2001 From: Tim Rupp Date: Sat, 16 Jul 2016 00:41:57 -0700 Subject: [PATCH] Adds style conventions to bigip_monitor_http (#2564) A number of coding conventions have been adopted for new F5 modules that are in development. To ensure common usage across the modules, this module needed to be updated to reflect those conventions. No functional code changes were made. --- network/f5/bigip_monitor_http.py | 424 ++++++++++++++++--------------- 1 file changed, 213 insertions(+), 211 deletions(-) diff --git a/network/f5/bigip_monitor_http.py b/network/f5/bigip_monitor_http.py index 0c6b15936b1..86096e95a2c 100644 --- a/network/f5/bigip_monitor_http.py +++ b/network/f5/bigip_monitor_http.py @@ -1,6 +1,6 @@ #!/usr/bin/python # -*- coding: utf-8 -*- - +# # (c) 2013, serge van Ginderachter # based on Matt Hite's bigip_pool module # (c) 2013, Matt Hite @@ -25,160 +25,163 @@ DOCUMENTATION = ''' module: bigip_monitor_http short_description: "Manages F5 BIG-IP LTM http monitors" description: - - "Manages F5 BIG-IP LTM monitors via iControl SOAP API" + - Manages F5 BIG-IP LTM monitors via iControl SOAP API version_added: "1.4" author: - - Serge van Ginderachter (@srvg) - - Tim Rupp (@caphrim007) + - Serge van Ginderachter (@srvg) + - Tim Rupp (@caphrim007) notes: - - "Requires BIG-IP software version >= 11" - - "F5 developed module 'bigsuds' required (see http://devcentral.f5.com)" - - "Best run as a local_action in your playbook" - - "Monitor API documentation: https://devcentral.f5.com/wiki/iControl.LocalLB__Monitor.ashx" + - "Requires BIG-IP software version >= 11" + - "F5 developed module 'bigsuds' required (see http://devcentral.f5.com)" + - "Best run as a local_action in your playbook" + - "Monitor API documentation: https://devcentral.f5.com/wiki/iControl.LocalLB__Monitor.ashx" requirements: - - bigsuds + - bigsuds options: - server: - description: - - BIG-IP host - required: true - default: null - server_port: - description: - - BIG-IP server port - required: false - default: 443 - version_added: "2.2" - user: - description: - - BIG-IP username - required: true - default: null - password: - description: - - BIG-IP password - required: true - default: null - validate_certs: - description: - - If C(no), SSL certificates will not be validated.
