Requirements

Install Ansible collections:

ansible-galaxy install -r requirements.yml

Generate secrets by run ansible locally:

ansible localhost -m template -a "src=secrets.yml.j2 dest=secrets.yml"

Next create certificate authority and save the key at /etc/openstack-ca/private/ca.key and the certificate at /etc/openstack-ca/certs/ca.crt on the ca node. This can be done manually or with the copy_ca.yml playbook. Remember to use the passphrase from secrets_ca_key_pass to encrypt the key.

ansible-playbook copy_ca.yml --extra-vars "ca_cert_path=./my-ca.crt ca_key_path=./my-ca.key"

To install the certificate authority into the system and start a few initial tasks run:

ansible-playbook main.yml --tags ca,bootstrap --extra-vars "ca_install_trust=true bootstrap_system_upgrade=true"

Finally restart all nodes.

Installation

ansible-playbook main.yml

Discover new compute nodes

ansible controller1 -m shell -b -a 'su -s /bin/sh -c "nova-manage cell_v2 discover_hosts" nova'

Upgrade

Set bootstrap_openstack_release to new release and run:

ansible-playbook main.yml --tags bootstrap

This will install the new package repository. Next upgrade OpenStack and run the database migrations for the new release by executing:

ansible-playbook main.yml --extra-vars "package_state=latest" --tags openstack

Upgrade all other packages and restart at least httpd:

ansible-playbook main.yml --tags bootstrap --extra-vars "bootstrap_system_upgrade=true"
ansible controller_nodes -m systemd -b -a "name=httpd state=restarted"

Finally remove the old package repository:

sudo dnf repository-packages centos-openstack-ussuri remove-or-reinstall
sudo dnf remove centos-release-openstack-ussuri
