there was missed conf in /etc/nova/nova.conf related to glance part.

please check below

https://docs.openstack.org/ocata/install-guide-rdo/nova-controller-install.html#finalize-installation

[Matt Riedemann (mriedem)]

You didn't have [glance]/api_servers configured in nova.conf, that's shown by the stacktrace in the nova-api logs which shows this:

2017-09-18 14:10:00.256 3224 ERROR nova.api.openstack.extensions for api_server in CONF.glance.api_servers:
2017-09-18 14:10:00.256 3224 ERROR nova.api.openstack.extensions TypeError: 'NoneType' object is not iterable

[Matt Riedemann (mriedem)]

https://docs.openstack.org/ocata/install-guide-rdo/nova-controller-install.html#finalize-installation says:

    In the [glance] section, configure the location of the Image service API:

    [glance]
    # ...
    api_servers = http://controller:9292

So you missed a step.
