What I am trying to say is, the Openstack is just complex, there is no way around, sysadmins just need to understand, what they are doing. If we are going to simplify that, we would need to build something like we have in UI. So some abstraction layer that leads the user and won't let him break it.

In general the CLI workflow is on the same conceptual level as Tuskar UI, so that's fine, we just need to use more commands than "tuskar". There's one naming mismatch though -- Tuskar UI doesn't use Horizon's Flavor management, but implements its own and calls it Node Profiles. I'm a bit hesitant to do the same thing on CLI -- the most obvious option would be to make python-tuskarclient depend on python-novaclient and use a renamed Flavor management CLI. But that's wrong and high cost given that it's only about naming :) The above issue is once again a manifestation of the fact that Tuskar UI, despite its name, is not a UI for Tuskar, it is UI for a bit more services. If this becomes a greater problem, or if we want a top-notch CLI experience despite reimplementing bits that can be already done (just not in a super-friendly way), we could start thinking about building something like OpenStackClient CLI [2], but directed specifically at Undercloud/Tuskar needs and using undercloud naming. Another option would be to get Tuskar UI a bit closer back to the fact that Undercloud is OpenStack too, and keep the name "Flavors" instead of changing it to "Node Profiles". I wonder if that would be unwelcome to the Tuskar UI UX, though.

Re: [openstack-dev] [TripleO] Tuskar CLI UX
Yeah. This is a double bladed axe but i'm leaning towards naming flavors consistently a bit more too. Here's an attempt at +/- summary: "node profile" + a bit more descriptive for a newcomer imho - CLI renaming/reimplementing mentioned before - inconsistency dangers lurking in the deep - e.g. if an error message bubbles up from Nova all the way to the user, it might mention flavors, and if we talk 99% of time about node profiles, then user will not know what is meant in the error message. I'm a bit worried that we'll keep hitting things like this in the long run. While I agree with all of your points, this is the one that resonates with me the most. We won't be able to be 100% consistent with a rename (exceptions are a great example). It's already irritating to the user to have to see an error, having to then see it in terms they aren't familiar with is an added headache. - developers still often call them "flavors", because that's what Nova calls them "flavor" + fits with the rest, does not cause communication or development problems - not so descriptive (but i agree with you - OpenStack admins will already be familiar what "flavor" means in the overcloud, and i think they'd be able to infer what it means in the undercloud) I'm CCing Jarda as this affects his work quite a lot and i think he'll have some insight+opinion (he's on PTO now so it might take some time before he gets to this). One other thing, I've looked at my own examples so far, so I didn't really think about this but seeing it written down, I've realised the way we specify the roles in the Tuskar CLI really bugs me. --roles 1=1 \ --roles 2=1 I know what this means, but even reading it now I think: One equals one? Two equals one? What? I think we should probably change the arg name and also refer to roles by name. --role-count compute=10 and a shorter option -R compute=10 Yeah this is https://bugs.launchpad.net/tuskar/+bug/1281051 I agree with you on the solution (rename long option, support lookup by names, add a short option).

If you are trying to hide the rest of the APIs then this is not the CLI that you seek. OSC doesn't assume that a user has access to only one or one type of cloud, so disabling/removing commands simply based on package installation is not a good user experience. Everything after that requires authentication to get server API versions and a service catalog to know what a specific cloud offers.

I'll leave it more that I think it is a lesser UX (not even saying bad, just not great) to have so much for the end user to digest to attempt to even play with it. I'm more of the mentality of a unified TripleO CLI that would be catered towards handling TripleO stuffs. Short of OpenStackClient, I realize I'm not exactly in the majority here, but figured it didn't hurt to spell out my opinion :) In general the CLI workflow is on the same conceptual level as Tuskar UI, so that's fine, we just need to use more commands than "tuskar". There's one naming mismatch though -- Tuskar UI doesn't use Horizon's Flavor management, but implements its own and calls it Node Profiles. I'm a bit hesitant to do the same thing on CLI -- the most obvious option would be to make python-tuskarclient depend on python-novaclient and use a renamed Flavor management CLI. But that's wrong and high cost given that it's only about naming :) The above issue is once again a manifestation of the fact that Tuskar UI, despite its name, is not a UI for Tuskar, it is UI for a bit more services. If this becomes a greater problem, or if we want a top-notch CLI experience despite reimplementing bits that can be already done (just not in a super-friendly way), we could start thinking about building something like OpenStackClient CLI [2], but directed specifically at Undercloud/Tuskar needs and using undercloud naming. Another option would be to get Tuskar UI a bit closer back to the fact that Undercloud is OpenStack too, and keep the name "Flavors" instead of changing it to "Node Profiles". I wonder if that would be unwelcome to the Tuskar UI UX, though.
