[tripleo][openstack-ansible] collaboration on os_tempest role update XII - Feb 26, 2019
by Chandan kumar 26 Feb '19

26 Feb '19

Hello, Here is the 11th update (Feb 20 to Feb 26, 2019) on collaboration on os_tempest[1] role between TripleO and OpenStack-Ansible projects. Summary: * os_tempest got the support of enabling/disabling stackviz report generation It will help end-user to save them for generating stackviz report each time while testing locally. * If OVN is used always select tempest_private_net_provider_type to geneve while running os_tempest or tempest with different installer. Things got merged os_tempest * Revert "Only init a workspace if doesn't exists" - https://review.openstack.org/637801 * Add iputils to use the ping command - https://review.openstack.org/638189 * Fix redhat iputtils - https://review.openstack.org/638444 * Remove the private option from include_role - https://review.openstack.org/638557 * use tempest_run_stackviz to generate stackviz report - https://review.openstack.org/638360 tripleo * Set tempest_private_net_provider_type to geneve for os_tempest - https://review.openstack.org/637838 Things in progress: os_tempest * update depenencies for os_tempest: https://review.openstack.org/#/q/topic:os_tempest_deps+(status:open+OR+stat… * Enable heat support in os_tempest: https://review.openstack.org/#/q/topic:os_tempest_heat+(status:open+OR+stat… * Update workspace tempest.conf on changes - https://review.openstack.org/638014 Some interesting stuff coming: * since os_tempest is integrated with tripleo, now we have os_tempest playbook where we have more than 19 vars passed to os_tempest in order to run it. Where we are going to keep those vars so that end user can run it easily. Related reviews: * os_tempest - move deployment tool related vars to vars dir - https://review.openstack.org/639258 * tripleo - Standardize os_tempest playbook and set vars dynamically - https://review.openstack.org/639310 * whether to ship config_template action plugin as pypi deps - https://review.openstack.org/#/c/638383/ Feel free to join today's OSA meeting on #openstack-ansible channel at 16:00 UTC, we will try to get some interesting discussions. <https://wiki.openstack.org/wiki/Meetings/openstack-ansible> Thanks to cjloader (for iputils patch), arxcruz & jrosser on stackviz, evrardjp on config_template as os_tempest deps and cloudnull for always reviewing our patches. Here is the 11th update [2]. Have queries, Feel free to ping us on #tripleo or #openstack-ansible channel.

[dev][qa][tempest-plugins] Fixing the setting and usage of service_availability config option in tempest plugins
by Ghanshyam Mann 26 Feb '19

26 Feb '19

HI All, After we split all the tempest plugins into the separate repo, service_available.<service-name> registration is in happening in the corresponding tempest plugins with default value as true. Example [1]. This leave service_available.<service-name> config options might have incorrect value and its incorrect usage when it is used in cross tempest plugin. Bugs[2] Recently Octavia-tempest-plugin faced the issue of duplicating the registration of same config option[3]. Previously Devstack used to set all the service_available config option which will be removed as devstack should be responsible to take care of 6 services only owned by Tempest and rest all goes on the service's devstack plugin side [4]. Current problem: 1. service_available.<service-name> default value is True and not set based on actual service availability. 2. tempest plugins need required tempest plugin to installed which register service_available.<service-name> config option but they are not in requirement.txt. To fix both problems, we need to do fixes in service and tempest plugin side. 1. Devstack should set only tempest own services - https://review.openstack.org/#/c/619973/ 2. each plugin to set their service as service_availability in their devstack plugin - In progress 3. Change the default value of service_available.<service> config option default value to false. 4. Add used tempest plugins in tempest plugins's requirements.txt after adding it in g-r. step#3 which change the config option default value from True to False will be done after step#2, to avoid any backward incompatible changes in term of skip the tests in any job. Third party CI reply on that default value has to set its value based on actual service availability check if they do not do currently. I am going to push the patches on service and plugin side, please let me know your opinion, feedback or any concern on this approach.

[nova]Supporting volume_name when booting from volume
by Rambo 26 Feb '19

26 Feb '19

Hi,all Currently, when creating a new boot-from-volume instance, the user can only control the name of the volume by pre-creating a bootable image-backed volume with the desired name in cinder and providing it to nova during the boot process. It is not friendly to the user when we want to use the desired name volume to boot instance. What do you think of this suggestion? Can you tell me more about this ?Thank you very much. Best Regards Rambo

[baremetal-sig][ironic] Proposing Formation of Bare Metal SIG
by Chris Hoge 25 Feb '19

25 Feb '19

This morning at the OpenStack Foundation board meeting we announced that we will focusing more our open infrastructure messaging efforts on bare-metal, and the promotion of Ironic in particular. To support these efforts, I'd like to form a Bare Metal SIG to bring together community members to collaborate on this work. The purpose of the Bare Metal SIG will be to promote the development and use of Ironic and other OpenStack bare-metal software. This will include marketing efforts like case studies of Ironic clusters in industry and academia, supporting integration of Ironic with projects like Airship and the Kubernetes Cluster API, coordinating presentations for industry events, developing documentation and tutorials, gathering feedback from the community on usage and feature gaps, and other broader community-facing efforts to encourage the adoption of Ironic as a bare-metal management tool. If you would like to participate, please indicate your interest in the linked planning etherpad. Ideally we would like to have broad engagement from across the community, from developers and practitioners alike. We'd like to highlight all of the efforts and usage across our community communicate how powerful Ironic is for hardware management. https://etherpad.openstack.org/p/bare-metal-sig Thanks in advance to everyone. I’ve been using Ironic to manage my home cluster for quite a while now, and I’m really excited to be working on the SIG and in supporting the efforts of the Ironic team and the users who are running Ironic in production.

If project_only=False, the db call may return other project's instance.

[dev][keystone] App Cred Capabilities Update
by Colleen Murphy 25 Feb '19

25 Feb '19

I have an initial draft of application credential capabilities available for review[1]. The spec[2] was not straightforward to implement. There were a few parts that I found unintuitive, user-unfriendly, and overcomplicated. The current proposed implementation differs from the spec in some ways that I want to discuss with the team. Given that non-client library freeze is next week, and the changes we need in keystonemiddleware also require changes in keystoneclient, I'm not sure there is enough time to properly flesh this out and allow for thorough code review, but if we miss the deadline we can be ready to get this in in the beginning of next cycle (with apologies to everyone waiting on this feature - I just want to make sure we get it right with minimal regrets). * Naming As always, naming is hard. In the spec, we've called the property that is attached to the app cred "capabilities" (for the sake of this email I'm going to call it user-created-rules), and we've called the operator-configured list of available endpoints "permissible path templates" (for the sake of this email I'm going to call it operator-created-rules). I find both confusing and awkward. "Permissible path templates" is not a great name because the rule is actually about more than just the path, it's about the request as a whole, including the method. I'd like to avoid saying "template" too because that evokes a picture of something like a Jinja or ERB template, which is not what this is, and because I'd like to avoid the whole string substitution thing - more on that below. In the implementation, I've renamed the operator-created-rules to "access rules". I stole this from Istio after Adam pointed out they have a really similar concept[3]. I really like this name because I think it well-describes the thing we're building without already being overloaded. So far, I've kept the user-created-rules as "capabilities" but I'm not a fan of it because it's an overloaded word and not very descriptive, although in my opinion it is still more descriptive than "whitelist" which is what we were originally going to call it. It might make sense to relate this property somehow to the operator-created-rules - perhaps by calling it access_rules_list, or granted_access_rules. Or we could call *this* thing the access rules, and call the other thing allowed_access_rules or permitted_access_rules. * Substitutions The way the spec lays out variable components of the URL paths for both user-created-rules and operator-created-rules is unnecessarily complex and in some cases faulty. The only way I can explain how complicated it is is to try to give an example: Let's say we want to allow a user to create an application credential that allows the holder to issue a GET request on the identity API that looks like /v3/projects/ef7284b4-3a75-4570-8ea8-b30214f18538/tags/foobar. The spec says that the string '/v3/projects/{project_id}/tags/{tag}' is what should be provided verbatim in the "path" attribute of a "capability", then there should be a "substitutions" attribute that sets {"tag": "foobar"}, then the project_id should be taken from the token scope at app cred usage time. When the capability is validated against the operator-created-rules at app cred creation time, it needs to check that the path string matches exactly, that the keys of the "substitutions" dict matches the "user template keys" list, and that keys required by the "context template keys" are provided by the token context. Taking the project ID, domain ID, or user ID from the token scope is not going to work because some of these APIs may actually be system-scoped APIs - it's just not a hard and fast rule that a project/domain/user ID in the URL maps to the same user and scope of the token used to create it. Once we do away with that, it stops making sense to have a separate attribute for the user-provided substitutions when they could just include that in the URL path to begin with. So the proposed implementation simply allows the wildcards * and ** in both the operator-created-rules and user-created-rules, no python-formatting variable substitutions. * UUIDs The spec says each operator-created-rule should have its own UUID, and the end user needs to look up and provide this UUID when they create the app cred rule. This has the benefit of having a fast lookup because we've put the onus on the user to look up the rule themselves, but I think it is very user-unfriendly. In the proposed implementation, I've done away with UUIDs on the operator-created-rules, and instead a match is looked up based on the service type, request path and method, and the "allow_chained" attribute (more on that next). Depending on how big we think this list of APIs will get, this will have some impact on performance on creation time (not at token validation time). UUIDs make sense for singleton resources that are created in a database. I imagine this starting as an operator-managed configuration file, and maybe some day in the future a catalog of this sort could be published by the services so that the operator doesn't have to maintain it themselves. To that end, I've implemented the operator-created-rules driver with a JSON file backend. But with this style of implementation, including UUIDs for every rule is awkward - it only makes sense if we're generating the resources within keystone and storing them in a database. * allow_chained The allow_chained attribute looks and feels awkward and adds complexity to the code Is there really a case when either the user or operator would not want to allow a service to make a request on behalf of a user who is making a more general request? Also, can we find a better name for it? Those are all the major question marks for me. There are some other minor differentiations from the spec and I will propose an update that makes it consistent with reality after we have these other questions sorted out.
