-To tell the KO which version of Kiali or OSSMC to install, you set the `spec.version` field in the Kiali CR or OSSMConsole CR. If no `spec.version` is defined in the CR, the default Ansible role that is executed is defined in link:https://github.com/kiali/kiali-operator/blob/master/playbooks/default-playbook.yml[default-playbook.yml] (side note: the file, and the field inside it, are technically named incorrectly. This isn't the default _playbook_, instead it is the default _role_. But ignore that.) Today, the default version of the Ansible role that is invoked is called, literally, link:https://github.com/kiali/kiali-operator/tree/master/roles/default[default]. This `default` version is the only one that the upstream Kiali project officially supports. This version support is provided for use by other products that want to retain support for earlier Kiali versions (such as Red Hat OpenShift Service Mesh).

If no `spec.version` is defined in the CR, an error will result and the KO will abort. To use the default Ansible role, set `spec.version` to the literal string `default`.
