Openstack 2024.1 Caracal to 2024.2 Dalmatian Upgrade

In this article I will show you how to upgrade the OpenStack version from 2024.1 to 2024.2 using Kolla-Ansible. A version upgrade is performed if the cluster has a bug and the bug has been fixed in the latest version, it can also be if there are new features in the latest version. I use Kolla-Ansible to upgrade the OpenStack version automatically.

So, let's get started…

Environment

Openstack Upgrade

1. Keep monitoring

2. Check docker images

3. Upgrade kolla-ansible

source os-venv/bin/activate
pip install --upgrade git+https://opendev.org/openstack/kolla-ansible@stable/2024.2

4. Upgrade ansible

pip install --upgrade 'ansible-core>=2.16,<2.17.99'

5. Install ansible galaxy dependencies

kolla-ansible install-deps

9. Generate and merge kolla password

mv /etc/kolla/passwords.yml /etc/kolla/passwords.yml-2024.1
cp os-venv/share/kolla-ansible/etc_examples/kolla/passwords.yml /etc/kolla/passwords.yml-2024.2
kolla-genpwd -p /etc/kolla/passwords.yml-2024.2
kolla-mergepwd --old /etc/kolla/passwords.yml-2024.1 --new /etc/kolla/passwords.yml-2024.2 --final /etc/kolla/passwords.yml

10. Update release version on kolla main configuration

nano /etc/kolla/globals.yml
---
openstack_release: "2024.2"

11. Copy Copy all-in-one 2024.2 inventory to kolla directory

mv all-in-one all-in-one.2024.1
cp os-venv/share/kolla-ansible/ansible/inventory/all-in-one .
mkdir -p /etc/kolla/ansible/inventory/
cp all-in-one /etc/kolla/ansible/inventory/

11. Pull openstack 2024.2 image

kolla-ansible pull

12. Pre-upgrade check

kolla-ansible prechecks

13. Update certificates

kolla-ansible certificates
update-ca-certificates
cat /etc/kolla/certificates/ca/root.crt >> /etc/ssl/certs/ca-certificates.crt

or

mv /etc/kolla/certificates /etc/kolla/certificates-2024.1
update-ca-certificates
kolla-ansible certificates
cat /etc/kolla/certificates/ca/root.crt >> /etc/ssl/certs/ca-certificates.crt

because I had this issue when upgrading

14. Openstack upgrade

kolla-ansible upgrade

Impact:

After upgrade process completed:

Operational Test

1. Verify docker images

docker ps -a

2. Operational test

openstack server create --image cirros-0.5.2-image --flavor tiny --key-name at-openstack-aio-key --network internal-net --security-group allow-all vm-cirros-2024.2

3. Prune 2024.1 docker images

docker image prune -af
