Minor upgrades¶

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 14.2.5
```
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
