How to Update Kolla images

Updating your cloud's Kolla images is an important part of improving the security of your OpenStack cloud. Improvements, bug fixes, and security patches for OpenStack services are also a benefit of updating your cloud's images.

Prepare Kolla Ansible​

To update the Kolla images, first prepare your Kolla Ansible environment.

Freeze changes to cloud​

Make sure the OpenStack service databases are not modified during this maintenance window. This includes things like creating/deleting VMs, networks, routers, etc.

Backup OpenStack databases​

Back up your cloud's MariaDB databases, just in case.

kolla-ansible -i inventory.yml -i ansible/inventory/multinode mariadb_backup

Pull images​

Pull in updated Kolla images. You can confirm when image updates are available by visiting Kolla Image Build History.

kolla-ansible -i inventory.yml -i ansible/inventory/multinode pull

Kolla deploy-containers​

Deploy updated containers.

kolla-ansible -i inventory.yml -i ansible/inventory/multinode deploy-containers

(Optional) MariaDB recovery​

If you run into issues with MariaDB containers not starting up during the deployment of containers, you can try recovering MariaDB.

kolla-ansible -i inventory.yml -i ansible/inventory/multinode mariadb_recovery
