Tip

You may need to provide custom values to configure your openstack services, for a simple single region or lab deployment you can supply an additional overrides flag using the example found at base-helm-configs/aio-example-openstack-overrides.yaml. In other cases such as a multi-region deployment you may want to view the Multi-Region Support guide to for a workflow solution.

Note

The above command is setting the ceph as disabled. While the K8S infrastructure has Ceph, we're not exposing ceph to our openstack environment.

If running in an environment that doesn't have hardware virtualization extensions add the following two set switches to the install command.

--set conf.nova.libvirt.virt_type=qemu --set conf.nova.libvirt.cpu_mode=none
