[openstackclient] Consistency between OSC commands >>> consistency with legacy clients
by Stephen Finucane 25 Nov '22

25 Nov '22

👋 tl;dr: $subject I reviewed a patch against openstackclient (OSC) today [1] and left a rather lengthy comment that I thought worthy of bringing up to a wider audience. The patch itself doesn't matter so much as what is was trying to achieve, namely modifying an existing OSC command to better match the structure of the equivalent legacy client command. The review provides more detail than I do here but the tl;dr: is that this is a big no-no and OSC will and must maintain consistency between OSC commands over consistency with legacy clients. As I noted in the review, consistency is one of the biggest advantages of OSC over the legacy clients: if you know the name of the resource type you wish to work with, you can pretty accurately guess the command and its structure. This is a thing that operators have consistently said they love about OSC and its one of the key reasons we're trying to get every command to provide full current API implementations in OSC (and SDK). Now I get that the way some of these consistent commands have been implemented has been the cause of contention in the past. I don't imagine it remains any less contentious today. However, these patterns are well-understood, well-known patterns that have for the most part worked just fine for close to a decade now. The kind of patterns I'm thinking about include: * The command to create a new resource should always take the format '<resource> create <human-readable identifer> * The command to modify some property of a resource should always take the format '<resource> set --property=value <name-or-identifier>' * The command to list, fetch or delete resources should always take the format '<resource> list', '<resource> get <name-or-identifier>', and '<resource> delete <name-or-identifier>', respectively. * Boolean options should always take the form of flags with an alternate negative option like '--flag' and '--no-flag', rather than '-- flag=<true|false>' * And a couple of other things that we tend to highlight in reviews. We want to preserve this behavior, lest OSC lose this huge USP and devolve into a muddle mess of different ideas and various individuals'/teams' preferences. I'm more than happy to discuss and debate this stuff with anyone who's interested and we'll continue reviewing each patch on its merit and providing exceptions to these rules where they make sense, but it will remain an ongoing goal and it's something we'd like people to consider when working on OSC itself or any of its plugins. I will now get off my pedestal/ivory tower 🗼 Thanks! Stephen PS: I'm talking here about the command themselves, not their implementations. We do somethings extra in OSC that are user helpful, like allowing users to identify resources by their name in addition to by their UUIDs. We also currently do things that no so user helpful, like crashing and burning if the name lookups fail (I'm thinking about the various Glance-related commands that error out if a project name/ID is passed to a command and the user can't look up that project). These are things we're more than willing to fix and will happily accept patches for :) [1] https://review.opendev.org/c/openstack/python-openstackclient/+/865377

[tacker] Tacker's Legacy API deprecation
by Ayumu Ueha (Fujitsu) 24 Nov '22

24 Nov '22

Hi Tacker users, Tacker team is going to mark the Tacker's Legacy APIs [1] (excluding VIM feature) to "deprecated" in Antelope cycle. Please see etherpad [2] about list of target APIs. We follow deprecation guideline [3] of OpenStack, and need to know how many users use Tacker's Legacy API. Please let me know if anyone still uses the Legacy API that will be marked "deprecated" via Rest-API or CLI(python-tackerclient) or GUI(tacker-horizon). If no one is using it, we will obsolete it in C cycle as planned. Thanks.

[CloudKitty] use of Monasca
by Rafael Weingärtner 24 Nov '22

24 Nov '22

Hello guys, As discussed in the PTG [1], in October, we wanted to check with the community if there are people using CloudKitty with Monasca. This discussion was brought up during the PTG that Kolla-ansible is deprecating support to Monasca, and we wanted to check if others are using CloudKitty with Monasca. This integration is not being actively tested and maintained; therefore, we are considering the issue of a deprecation notice and further removal of the integration. What do you guys think? Are there people using CloudKitty with Monasca? [1] https://etherpad.opendev.org/p/oct2022-ptg-cloudkitty -- Rafael Weingärtner
