#openstack-sdks - 2019-11-01
15:24:41 cdent no "standard" was set with regard to placement around queens time
15:24:53 umbSublime agreed, it was also a bit of an exercise to get more familiar with the SDK
15:25:11 efried unfortunate that you tried with this particular combination :(
15:25:30 efried We didn't have sdk talking to placement until mid-train, and iirc we had to make some tweaks to sdk to make that happen more smoothly.
15:25:38 umbSublime I appreciate all your help though. efried I think I'll give that technique you shared a try
15:26:02 cdent umbSublime: you can run placement standalone, if you want something to talk to using modern techniques, for educational purposes
15:26:40 umbSublime Ohh you mean on a devstack or something ?
15:27:01 cdent no, much more standalone, let me find you a ref
15:27:41 cdent https://docs.openstack.org/placement/latest/contributor/quick-dev.html as well as https://github.com/cdent/placedock
15:27:50 umbSublime One day I'll try and get more involved into dev in openstack currently I'm just an operator trying to make my life easier :)
15:28:19 cdent that would be great, openstack badly needs more people with field experience working on it to make it easier to manage
15:29:56 umbSublime to be honest I was wondering is there is some type of portal where openstack operators (which don't necesseraly have all the dev experience) could share and discuss some future features/bugs etc.
15:31:56 cdent the openstack-discuss mailing list is supposed to be, in part, for that
15:34:39 umbSublime What is the actual goal the SDK is trying to fill (not historically, but nowadays) ? Is it meant to be a one stop shop for os services needing to talk to another ? Or is it more dev/ops oriented to standardize talking to all the different APIs
15:35:46 mriedem umbSublime: #openstack-operators channel
15:35:52 mriedem though it's generally quiet
15:35:58 efried umbSublime: That's really a mordred (sitting shirtless on a mountain with supplicants bringing him burnt offerings) question.
15:36:11 efried but I'll give it a shot...
15:36:25 mriedem umbSublime: if you send to the ML, tag ops stuff with [ops] to filter properly in people's mailbox
15:37:01 efried Yes, one stop shop. Originally I think for cloud operators writing tooling that talks to their cloud. Yes standardize how we talk to the different APIs.
15:37:25 efried Only more recently have we started to want to use it as a way for one service to talk to another.
15:37:34 umbSublime hence the merge of shade into the sdk in the bigining
15:38:12 efried We made some inroads on that in nova in train: we're most of the way through replacing nova's use of python-ironicclient with sdk; and we already swapped out placement (which had been using ksa directly) as you saw.
15:54:30 umbSublime efried: One last question concerning using get_ksa_adapter. Here https://opendev.org/openstack/nova/src/branch/master/nova/conf/placement.py#L28 what is conf ? I know it's what you showed with the .ini style config. But what type of object do I use to generate it ?
15:59:24 efried umbSublime: it's something like:
15:59:25 efried from oslo_config import cfg
15:59:25 efried register_ksa_options(..) # This should register the opts onto cfg.CONF
15:59:25 efried cfg.CONF(args=['--conf-file', '/path/to/your.conf']) # This loads up your config file into cfg.CONF
15:59:25 efried get_ksa_adapter...
15:59:36 efried gotta run to a meeting, that ^ is a bit rough but hopefully gets you pointed in the right direction.
16:00:19 umbSublime efried: thanks that's exactly what I need :)

17:25:57 openstackgerrit Merged openstack/python-openstackclient master: versions: Fix 'versions show' help message https://review.opendev.org/686408
17:29:13 umbSublime I must be missing something https://hastebin.com/utuhuyinur.python I don't see what could be a duplicate. I'm trying to dig in the code, but i'm a bit lost
17:35:27 efried umbSublime: You're just running this code in isolation?
17:38:09 openstackgerrit Pierre Prinetti proposed openstack/python-openstackclient master: Fix 'versions show' helps & docs https://review.opendev.org/691989
17:38:15 efried umbSublime: It looks right to me, but I was able to repro locally. Investigating...
17:40:37 umbSublime efried: yes, only the code in hastebin in a venv
17:43:26 efried umbSublime: oh, I see what's happening. I didn't notice you were importing from nova. That import is already registering the conf opts via nova.conf.__init__.
17:43:58 efried If you want to be able to use this cleanly, I suggest just copying in the guts of register_ksa_options
17:44:08 efried ...so you don't need to rely on nova existing at all.
17:44:17 umbSublime Ohh I see what you mean.
17:45:08 efried umbSublime: Um, except you can simplify a lot further
17:45:21 efried you don't need to remove and re-add the _ADAPTER_VERSION_OPTS for your purposes.
17:45:38 efried though I guess you can, shrug.
17:46:05 umbSublime same for get_ksa_adapter (I just use the guts of the function) ?

17:50:14 openstackgerrit Pierre Prinetti proposed openstack/python-openstackclient master: Fix 'versions show' helps & docs https://review.opendev.org/691989
18:04:15 umbSublime got it working. Thanks again efried !
18:04:24 efried \o/
18:13:47 umbSublime Here is what I end up with https://hastebin.com/huhajekiso.py
18:15:48 efried umbSublime: Some of that stuff is nova-specific and/or legacy gorp you're dragging along. If this is for more than just playing around, I would suggest simplifying.
18:16:59 umbSublime efried: yup. I'm doing that right now :) but being unfamiliar with the codebase i'm taking my time :)
18:17:01 efried but yeah, this looks good.
18:17:12 efried umbSublime: okay, let me know if you need help
18:17:31 efried for example, if this is always going to be a placement-specific tool, you can remove all the stuff about service types and just hardcode 'placement'.
18:17:51 efried and as I said before, you probably don't care to scrub those version opts for your purposes.
18:17:57 umbSublime Well I'm baking this into my more general purpuse lib module, so I'll try and keep it generic
18:18:05 umbSublime just in case I need it for another service at some point
18:18:14 efried mmkay
18:18:30 umbSublime efried: I tried without and I get the same stack-trace as when using the nova register_ksa_opts
18:18:52 efried you would need to remove that hackup from both places
18:19:43 efried so 1) get_ksa_adapter_opts can go away and just use ks_loading.get_adapter_opts directly; and 2) kill L36-8
18:20:17 umbSublime Ohhh I see, remove lines for "Removing version opts" and the ones that "add dummy opts for version"
18:20:47 efried actually, it gets simpler.
18:21:32 efried I only did this conf.register(get_opts) thing because I had to hack out those version things.
18:22:07 efried There ought to be a ks_loading method like ks_loading.register_adapter_conf_options which you can call directly.
18:22:54 umbSublime Ok, I'll look into that
18:30:48 efried umbSublime: like this http://paste.openstack.org/show/785725/
18:37:58 umbSublime For some reason i'm getting "keystoneauth1.exceptions.catalog.EndpointNotFound: Could not find requested endpoint in Service Catalog." with that code (adapted to my env of course)
18:39:14 efried add to your conf:
18:39:15 efried service_type = placement
18:39:39 efried I simplified out the bit that detects that :P
18:39:48 efried here's super pared down: http://paste.openstack.org/show/785726/
18:40:38 efried btw, raise_exc=False means that for 4xx/5xx responses, instead of raising an exception, you still just get a Response back, which you can inspect yourself.
18:40:45 umbSublime this fixed it for me http://paste.openstack.org/show/785727/
18:41:06 umbSublime ohh very neat trick !
18:41:45 efried and Response has a magic __bool__ so you can actually say things like:
18:41:45 efried if resp:
18:41:45 efried # status code was 2xx/3xx, do success path
18:41:45 efried else:
18:41:45 efried # status code was 4xx/5xx, do failure stuff
18:42:19 efried umbSublime: yes, what fixed you there was the cfg.set_defaults(service_type='placement') which is the same thing as you setting it in the conf (but in code)
18:42:49 efried so, either way
18:43:05 umbSublime \o/
18:50:33 umbSublime Say I want to wrap all this in a function that takes a region_name and return the adapter for the specified region. I'd need to do something similar to "example 3" and then do CONF(['--my-opt', "my_val"]) https://www.programcreek.com/python/example/106145/oslo_config.cfg.CONF
19:02:17 umbSublime Ahh even easier I can just override the region_name attribute from the adapter
19:15:09 efried depending where in the flow you want to do it, you could do CONF.set_override(region_name='foo', group='placement')
19:15:16 efried (I may not have that syntax exactly right)
