#openstack-nova - 2020-06-18
18:10:00 mordred so a git grep wasn't finding it - that makes sense
18:10:02 mordred efried: thanks!
18:10:04 efried yw
18:10:39 efried not sure about 'sphinx', but generated by doc build, yes.
18:11:31 efried ...and I think it comes in by virtue of the `list_opts()` methods in conf/*, e.g. https://github.com/openstack/nova/blob/master/nova/conf/glance.py#L173
18:11:49 efried ...which as you can see uses ksa's methods for generating those
18:13:07 mordred efried: yah. \o/ yay
18:19:34 sangeet ten thousand thansk modred .. it worked. I am so exicted. QQ Do I need to put it under idenity also or neutron, glance and placement is enough?
18:19:53 sangeet Sorry *mordred ^^
18:21:12 sean-k-mooney mordred: i was expecting to find it here https://docs.openstack.org/nova/latest/admin/security.html
18:21:37 sean-k-mooney mordred: although the install guide would make sense
18:22:15 sean-k-mooney efried: mordred i dont think the config guide is really helpful in this case
18:22:47 sean-k-mooney that is where i started but i did not find it mainly because i was looking for ca_
18:22:55 sean-k-mooney but it was not obvious
18:23:25 efried I don't think we should describe the optinos in depth in the security guide, but it would be sane to refer to the config docs from there.
18:24:42 sean-k-mooney yep that is what i was thinking too altough i think having a secting in the install guide would make sense
18:24:49 sean-k-mooney e.g. how to isntall with tls?
18:27:07 sangeet I agree .. that would be an excellent idea
18:28:56 mordred sangeet: you'll likely need to put it in for each service you're using
18:29:24 mordred sangeet: so - yeah - I'd do identity I think
18:38:41 sangeet Thank you mordred
19:12:44 sangeet mordred .. oops now my nova-conductor is not liking it when I try to create a server. I have set cafiles as we discussed above. "OSError: Could not find a suitable TLS CA certificate bundle, invalid path: /etc/nova/certs/ca.crt"
19:13:21 sangeet It seems conductor is expecting the CA file to be at some other location
19:17:38 mordred sangeet: are those on the same machine?
19:17:50 sangeet differnt pods
19:18:06 sangeet the file exist
19:18:45 mordred hrm. I'm not sure about that one - maybe someone else will know
19:19:34 sangeet sean-k-mooney efried .. please help ^^
19:20:31 efried I'm no expert here, so this is just a guess:
19:20:49 efried If you put this in [identity], it means all the nova services will try to use it when talking to keystone.
19:20:50 sangeet I am up for trying anything
19:21:05 efried So you need it on every node that's running any nova service (conductor, compute, scheduler, whatever)
19:21:15 efried it == the crt fil.
19:21:16 efried file
19:21:41 sangeet so put cafile=/etc/nova/certs/ca.crt under identity
19:21:53 efried eh? I thought that's what you did, and it didn't work
19:22:00 efried Let's back up.
19:22:06 efried What change did you make that's leading to this error?
19:22:07 sangeet I ut it in compute and not in conductore
19:22:30 sangeet Let me try to put it under identity also
19:22:39 efried waitwait
19:22:52 efried I haven't been following this conversation, so I don't want to lead you down a rabbit hole.
19:22:59 efried What exactly have you changed so far?
19:25:52 sangeet I have Keystone deployed with SSL. In my nova.conf I set cafile=/etc/nova/certs/ca.crt for [neutron], [glance], [keystone_authtoken], [placement]
19:26:53 efried Hm, okay, I'm not sure about [keystone_authtoken] -- that's to set up the server side of the keystone service.
19:27:29 efried But nova talks to some of those services from multiple places -- conductor, scheduler, compute.
19:27:40 efried I don't remember offhand which ones talk to which ones from where.
19:29:09 efried Also note that conductor and compute use different config files by default (unless that's changed, or unless you're on an old release), so if you're running both, you'll want to set up both files.
19:29:46 efried But honestly, beyond that, I'm really out of my depth. sean-k-mooney would probably be a better resource. He is EU, so maybe try again "tomorrow".
19:30:22 sangeet I am using stein and I do have different configs as they are running on a different pods
19:31:44 sean-k-mooney efried: is that a hint i should go get dinner because it should be just cooked :)
19:32:12 efried sean-k-mooney: yes, you should not be working right now.
19:32:52 efried sangeet: TL;DR: I suspect you need the crt file available/accessible on the same file system as the nova.conf file you're editing.
19:33:03 efried same file system in the same container etc.
19:33:13 sean-k-mooney efried: hehe if i had started at 11 like i normally do i would argue but since i started at 8am today, night all o/
19:33:32 efried But I'm also really not sure what mucking with [keystone_authtoken] did for you.
20:08:25 sangeet efried .. yes cafile needed to be set in identity section on conductor. It works now.
20:08:36 efried \o/
20:09:05 efried Not to confuse things, but is it possible it's *only* required in [identity]?
20:10:13 efried I don't know whether/where we talk to keystone as an actual client; we may just be using it to set up the connection to the other services. But... I really don't know how that all works.
20:17:34 mordred efried: yeah - I'm gonna try to do an audit through of that
20:17:47 efried cool
20:17:49 mordred efried: cause right now I think it's ... well, if you don't know and I don't know - then likely nobody knows
20:18:11 efried lbragstad might :P
20:18:26 efried or cmurphy. Or other people who are no longer stacking.
20:24:13 lbragstad i actually didn't realize nova had an identity section *and* a keystone_authtoken section
20:24:58 efried IIUC, the former is for talking to keystone as a client, and the latter is for setting nova up as a server.
20:24:59 lbragstad (the keystone_authtoken section comes from keystonemiddleware)
20:25:50 efried tbh, I'm not sure where we're actually using the former from nova. But we must be, or sangeet's change wouldn't have fixed the problem...
20:27:08 lbragstad yeah - iirc (and i'm probably dated here) [keystone_authtoken] is only invoked by keystonemiddleware to fetch information about tokens out of keystone
20:31:24 lbragstad ahh - it looks like the [identity] section is used to validate project IDs
20:31:39 efried "used" -- by nova?
20:32:07 efried or by, like, everyone who has one?
20:32:20 lbragstad https://opendev.org/openstack/nova/src/branch/master/nova/api/openstack/identity.py
20:33:18 efried Interesting.
20:33:35 lbragstad maybe? i might not be following this properly
20:34:35 lbragstad i think this is what i was looking at https://docs.openstack.org/nova/latest/configuration/config.html#keystone
20:34:37 efried Oh, that's for sure a place where we're using the [identity] section to create a ksa adapter that talks as a client to the keystone service's API.
20:35:07 lbragstad https://docs.openstack.org/nova/latest/configuration/config.html#keystone-authtoken is the keystonemiddleware section
20:35:11 efried Yeah, some layer of this translates $service_name to $project_name or vice versa
20:35:12 efried yes.
20:35:54 lbragstad i don't actually see an [identity] section
20:35:58 lbragstad in the configuration reference
20:36:06 lbragstad i see [keystone] and [keystone_authtoken]
20:36:19 efried I believe you're allowed to use either [identity] or [keystone] for anything we load up via get_{sdk|ksa}_adapter.
20:36:36 efried I mean, [$service] or [$project]
20:36:37 lbragstad oh - so service types and service names are interchangable?
20:36:48 lbragstad interchangeable*
20:36:54 efried only if we're using get_{sdk|ksa}_adapter.
20:37:02 efried Which I think we are for everything except cinder at this point.
20:37:07 lbragstad ok
20:37:38 efried And by "we" I mean "they". I don't work here anymore :P
20:38:09 lbragstad :)
21:02:16 mordred efried: I was about to ask you about cinder
21:02:22 mordred efried: I'm guessing I should put that on my list too
21:02:37 efried I made several attempts at it over the years, but they never quiiite landed.
21:02:42 mordred (mostly noticed that there's a weird os-region-name option)
21:02:50 efried I think there's still an open change under my name
21:03:09 mordred efried: cool. maybe I'll finish that - with your name on it it'll have more credibility
21:03:12 efried There were significant difficulties with the (in)compatibility between ksa and cinderclient.
