I would like to propose that once we have https://review.openstack.org/#/c/472731/ in place, we would force our users to generate roles_data.yaml instead of providing a default file. One direct benefit for that would be to solve this kind of case: https://bugs.launchpad.net/tripleo/+bug/1671859 (and possibly decrease deployment time when using custom roles). One way to do it could be: Pike - Validate roles data with https://review.openstack.org/#/c/472731/ - Make CLI generating by default the current default config (when not using custom roles) (if not the case already) - Document the CLI (in progress by Alex) and deprecate the roles_data file, make it clear in the documentation for our users. Queens - Remove the default roles data from THT - Make the roles data file management as required in the doc Does it make sense? > Of course while writing this email I noticed that tripleo-common also > pulls in instack-undercloud[3] like tripleoclient[4] so I'm not sure > this is actually an improvement. ¯\_(ツ)_/¯ > > Thanks, > -Alex > > [0] https://review.openstack.org/#/c/474332/ > [1] https://review.openstack.org/#/c/474343/ > [2] https://review.openstack.org/#/c/472731/ > [3] > https://github.com/rdo-packages/tripleo-common-distgit/blob/rpm-master/openstack-tripleo-common.spec#L21 > [4] > https://github.com/rdo-packages/tripleoclient-distgit/blob/rpm-master/python-tripleoclient.spec#L36 > >> >> Thanks, >> -Alex >> >>> >>> Dan >>> Instead if you have an update to a role, please update the appropriate roles/*.yaml file.

As a follow up, I've taken some time to move the roles functions in to tripleo-common[0] and out of tripleoclient[1]. With this, I've also updated the validation patch with a small python script that leverages the tripleo-common work.

So my original implementation of the roles stuff included a standalone script in THT to generate the roles_data.yaml files. This was -1'd as realistically the actions for managing this should probably live within python-tripleoclient. This made sense to me as that's how the end user really should be interacting with these things. Given that the tripleoclient and the UI are the two ways and operator is going to consume with THT I think there is already an undocumented requirement that should be there. An alternative would be to move the roles generation items into tripleo-common but then we would have to write two distinct ways of then executing this code.

I could add a role for a reference Ironic Conductor node. Hi, thanks for doing great work in this and bringing up the topic! I'd like to point out one problem which we've been dealing with for quite a while now which is TripleO UI and CLI interoperability. The main reason why we introduced Mistral 'TripleO' API is to consolidate the business logic to single place which will be used by all TripleO clients, so all will use the same codebase and not diverge. This has been established and agreed on quite a long time ago but it occurs that the problem of diverging the codebases still creeps in. Main problem is that CLI (unlike all other clients) still tends to operate on local files rather than a deployment plan stored in Swift. Result is that new features which should be implemented in single place (tripleo-common - Mistral Actions/Worklflows) are implemented twice - in tripleoclient and (usually later for no real reason) in tripleo-common. Roles management is exact example. There is a great effort made to simplifying and managing Roles, but only by CLI, regarless of other clients need to do the same. This causes us having to maintain 2 codebases which have the same goal, increases development time and other costs. So my question is: How much effort would it be to change CLI workflow to operate on plan in Swift rather on local files? What are the pros and cons? How do we solve the problem of lacking features in tripleo-common? Recently a changes in tripleo-common have been made which make operations on Swift plan much simpler. All the data about deployment is kept in Swift in templates/environment files and plan-environment.yaml (which replaced mistral environment data structure) so importing/exporting plan is much simpler now. If CLI leveraged this functionality, there would not be any need for user to store CLI command which was used for deployment. All the data are in plan-environment.yaml. Let's take a look at Roles management example. Alex mentions removing roles_data.yaml. Yes, there is no need for it. Deployment plan is pre-created with undercloud install already, so CLI user could list available roles and use command which sets roles (takes list of roles names), this calls Mistral action/workflow which stores this selection in plan-environment.yaml in Swift and regenerates/updates j2 templates. Same with anything else (add environment files add/modify templates, set parameters...). Then user just fires 'openstack overcloud deploy' and is done. In case of need, user can simply export the plan and keep the files locally to easily recreate same deployment elsewhere. What are the reasons why CLI could not work this way? Do those outweigh having to implement and maintain the business logic at two places?
