[Sean] By the looks of things though, one needs to go to the neutron CLI for certain things.
I think there is no easy-to-reach information on OpenStack Client.

If we assume that OpenStack client version is tied to OpenStack release [which is common use case for end users].
I think the situation is as follows (don’t hesitate to correct/add):

Nova: Most of support by Mitaka, full support targeted for Newton.
Neutron: Full support targeted for Newton
Keystone: Full support by Kilo
Cinder: most of support by Liberty, full: targeted for Newton
Glance: full support by Liberty
Swift: full support by Mitaka

1)    If above is correct - whether (<current>) CLI guide should contain OpenStack client commands for Nova/Neutron and Cinder by time of Newton release?

Well, documentation seems to be not very consistent.

Assumption should be that Nova/Neutron/Cinder are not supposed to be primarily used with OpenStack CLI client yet with Mitaka (/OSC 2.2.0)?

But for example Glance partly has command examples in UG (but not in cheat-sheet [1] ), but Swift is described using Swift client [3] in UG

2)    I suspect that non-core services are not covered by [2].

Example of that is Heat where Heat CLI will be deprecated by Newton [4] but [2] is not describing that.

FWIW folks have added *a lot* of cool network functionality lately, it's just all unreleased. See our release notes: http://docs.openstack.org/releasenotes/python-openstackclient/unreleased.html

Look for a 3.0.0 of OpenStackClient any day now

Thanks Darek, being new to openstack your links help me understand the situation much better.

The openstack client being used what that installed on a controller by Fuel v9/mikata, i.e. 2.2.0.
I’ll install 2.6.0 on my workstation and try from there.

[1] also links to python-openstacksdk, which looks (more) interesting, but there too all operations are not covered.
Don’t see much mention of domain support when clicking though the docs, so it is perhaps a major limitation if I need to work with ldap.

By the looks of things though, one needs to go to the neutron CLI for certain things.
The reference doc for using for neutron is http://docs.openstack.org/developer/python-neutronclient/ ?
Would it be correct to say that neutron only does v2 and cannot work with domains?

I wonder how horizon is able to “set conext” to a domain and then operations are valid with context.

Perhaps one need to just learn the API and program from there without any libraries or CLI wrappers.

Hey Sean,
Please remind, that transition is in progress. You can verify how far we are here [1].
But, according to OSC documentation [2] and release notes [3], you should be able to create subnet. It was released with OSC 2.4 version.

Could you verify, if you have correct version?
