TripleO currently relies on Kolla docker containers. Kolla supports container
customization and we are making use of this feature within TripleO to inject
-puppet (our configuration tool of choice) into the Kolla base images. To
-build Kolla images for TripleO adjust your kolla config to build your
+puppet (our configuration tool of choice) into the Kolla base images. The
+undercloud nova-scheduler also requires openstack-tripleo-common to
+provide custom filters.
+
+To build Kolla images for TripleO adjust your kolla config to build your
centos base image with puppet using the example below:
.. code-block::
$ cat template-overrides.j2
{% extends parent_template %}
{% set base_centos_binary_packages_append = ['puppet'] %}
+{% set nova_scheduler_packages_append = ['openstack-tripleo-common'] %}
kolla-build --base centos --template-override template-overrides.j2
