Note
To avoid issues and simplify troubleshooting during an upgrade, first disable the security hardening role by setting your variable apply_security_hardening to False in the user_variables.yml file.
A minor upgrade typically requires the following steps:
Change directory into the repository clone root directory:
# cd /opt/openstack-ansible
Ensure your OpenStack-Ansible code is on the latest Newton tagged release:
# git checkout 14.2.1
Update all the dependent roles to the latest version:
# ./scripts/bootstrap-ansible.sh
Change into the playbooks directory:
# cd playbooks
Update the hosts:
# openstack-ansible setup-hosts.yml
Update the infrastructure:
# openstack-ansible -e rabbitmq_upgrade=true \
setup-infrastructure.yml
Update all OpenStack services:
# openstack-ansible setup-openstack.yml
Note
Scope upgrades to specific OpenStack components by executing each of the component playbooks using groups.
For example:
Update only the Compute hosts:
# openstack-ansible os-nova-install.yml --limit nova_compute
Update only a single Compute host:
Note
Skipping the nova-key tag is necessary as the keys on all Compute hosts will not be gathered.
# openstack-ansible os-nova-install.yml --limit <node-name> \
--skip-tags 'nova-key'
To see which hosts belong to which groups, the inventory-manage.py script shows all groups and their hosts. For example:
Change directory into the repository clone root directory:
# cd /opt/openstack-ansible
Show all groups and which hosts belong to them:
# ./scripts/inventory-manage.py -G
Show all hosts and which groups they belong:
# ./scripts/inventory-manage.py -g
To see which hosts a playbook will execute against, and to see which tasks will execute.
Change directory into the repository clone playbooks directory:
# cd /opt/openstack-ansible/playbooks
See the hosts in the nova_compute group which a playbook executes against:
# openstack-ansible os-nova-install.yml --limit nova_compute \
--list-hosts
See the tasks which will be executed on hosts in the nova_compute group:
# openstack-ansible os-nova-install.yml --limit nova_compute \
--skip-tags 'nova-key' \
--list-tasks
