From fe4e9a4ca7028aa877fdd3895225a67b026aea11 Mon Sep 17 00:00:00 2001 From: Devan Goodwin Date: Thu, 5 Nov 2015 08:35:53 -0400 Subject: Upgrade improvements - Push config dir logic out of module and use host variables instead. - Backup master config with ansible utility. - Add error handling for the upgrade config module. - Add verbose option to installer. - Return details on what we changed when upgrading config. - Cleanup use of first master. - Don't install upgrade rpms to check what version we'll upgrade to. --- .../upgrades/library/openshift_upgrade_config.py | 53 +++++++-------- playbooks/adhoc/upgrades/upgrade.yml | 78 +++++++++------------- 2 files changed, 56 insertions(+), 75 deletions(-) (limited to 'playbooks/adhoc') diff --git a/playbooks/adhoc/upgrades/library/openshift_upgrade_config.py b/playbooks/adhoc/upgrades/library/openshift_upgrade_config.py index 60f4fd8b8..0894efa52 100755 --- a/playbooks/adhoc/upgrades/library/openshift_upgrade_config.py +++ b/playbooks/adhoc/upgrades/library/openshift_upgrade_config.py @@ -5,11 +5,8 @@ """Ansible module for modifying OpenShift configs during an upgrade""" import os -import shutil import yaml -from datetime import datetime -
