Playbooks¶

ansible_fact_cleanup.yml¶

This playbook calls a script to remove files in the /etc/openstack_deploy/ansible_facts/ directory.

deploy-config-changes.yml¶

This playbook backs up the /etc/openstack_deploy directory before changing the configuration.

The``/etc/openstack_deploy`` directory is copied once to the /etc/openstack_deploy.NEWTON directory.

user-secrets-adjustment.yml¶

This playbook ensures that the user secrets file is updated based on the example file in the main repository, making it possible to guarantee that all secrets move into the upgraded environment and are generated appropriately. This playbook adds only new secrets, such as those necessary for new services or new settings added to existing services. Values that were set previously are not changed.

pip-conf-removal.yml¶

The presence of the pip.conf file locks down all Python installations to packages on the repo servers. If this file exists on a repo server or a physical node, it causes a circular dependency issue and the upgrade fails. This playbook removes the file on all the repo servers and physical nodes.

setup-infrastructure.yml¶

The playbooks directory contains the setup-infrastructure.yml playbook. The run-upgrade.sh script calls the setup-insfrastructure.yml playbook with specific arguments to upgrade MariaDB and RabbitMQ.

For example, to run an upgrade for both components at once, run the following commands:

# openstack-ansible setup-infrastructure.yml -e 'rabbitmq_upgrade=true' \
  -e 'galera_upgrade=true'

The rabbitmq_upgrade variable tells the rabbitmq_server role to upgrade RabbitMQ.

The galera_upgrade variable tells the galera_server role to remove the current version of MariaDB and Galera and upgrade to the 10.*x* series.

memcached-flush.yml¶

This playbook sends the flush_all command to Memcached with the help of netcat.
