After deploy devstack in over cloud, I receive the error:

Is this opt essential? The guide don't include it.

[Kirill Zaitsev (kzaitsev)]

service_subnet is essential if you're going to use services in k8s. The guide should include it aswell. Please be aware, that services support is not fully merged yet — you need to apply https://review.openstack.org/#/c/376045/16 manually

[Antoni Segura Puimedon (celebdor)]

We should add it to the nested guide

    nested_doc: Fix lack of mention of service_subnet

    Now that services are merged, it is necessary to have it documented in
    the nested guide, otherwise it can lead to configuration mistakes.

    Include neutron_defaults group into oslo-config-generator output

    Previously this group was not included and calling
    ./tools/generate_config_file_samples.sh would not add these options to
    the sample config file. This commit fixes the inconsistency.
