Scripts
This section describes scripts that are used in the upgrade process in detail.
Within the main scripts directory there is a upgrade-utilities directory,
which contains additional scripts that facilitate the initial upgrade
process.
run-upgrade.sh
This script controls the overall upgrade process for deployers choosing not to do so manually.
It provides the following environment variables:
SCRIPTS_PATH- path to the top level scripts directoryMAIN_PATH- openstack_ansible root directory.UPGRADE_PLAYBOOKS- path to the playbooks used in upgrading
The upgrade script also bootstraps OpenStack-Ansible (using
bootstrap-ansible.sh) in order to provide the new role
dependencies introduced in the Mitaka series.
migrate_openstack_vars.py
Upstream decisions influenced the change of some variable names in
Newton. This script replaces any instances of these strings in the
variable override files matching the pattern
/etc/openstack_deploy/user_*.yml. Variable names within
comments are updated.
This script creates files of the form
/etc/openstack_deploy.NEWTON/VARS_MIGRATED_file. For
example, once the script has processed the file
/etc/openstack_deploy/user_variables.yml, it creates
/etc/openstack_deploy.NEWTON/VARS_MIGRATED_user_variables.
This indicates to OpenStack-Ansible to skip this step on successive
runs. The script itself does not check for this file.
The variable changes are shown in the following table.
