smcginnisjokke_: Looks like it's in releasenotes/notes/train-final-e09f3fe40592a478.yaml, but I can't figure out yet what it doesn't like about it.14:34
jokke_configs are in sync14:37
jokke_I think it was the fixes; empty line after -|14:38
rosmaitajokke_: don't know if you care, but the single backticks give you italics, if you want monospace font for the commands, you need to use ``14:39
*** pcaruana has quit IRC14:39
jokke_if it passess I don't care, if I need to poke it I'll chnge them and try to remember next time, thanks14:41

smcginnisjokke_: It passed for me after removing the prelude section, so I think it's something there.14:55
smcginnisFixes were fine.14:55
jokke_I can't get the build runing locally, can you test for me if it rnders correctly the prelude lines changed as following:14:58
jokke_prelude:14:58
jokke_  -|14:58
jokke_to prelude: |14:59
smcginnisjokke_: You can't run tox -e releasenotes?14:59
jokke_nope, breaks horribly wall of red for some reason14:59
jokke_I think I have somme prerequisite missing that is not coming from pip14:59
smcginnisWhat about rebuilding the venv? tox -re releasenotes15:00
jokke_did not help15:00
smcginnisHuh, weird.15:00
jokke_tried that as first thing15:00
rosmaitai'll download and take a look15:00
smcginnisI made that change and it looks like that does it ^^15:00
jokke_kk ps3 inbound15:01
*** jmlowe has joined #openstack-glance15:01
*** pcaruana has joined #openstack-glance15:01
jokke_that should do the trick then15:03
jokke_ha I'm bit by bit getting the grasp of basics in reno formatting :P15:04
smcginnisIt's definitely not always intuitive.15:04
smcginnisWould be nice if the failures actually gave some clues where to look at least.15:05
smcginnisHmm, we don't have gerrit notificiations in channel for stable patches?15:05
smcginnisIs that on purpose?15:05
*** efried has joined #openstack-glance15:08
efriedo/ glance!15:08
jokke_I don't know. I think we never did15:08
jokke_hi efried15:08
smcginnisUh oh, it's efried. Hide.15:08
jokke_smcginnis: I put release patch up wiht depends on15:08
efriedI'm about to show some dramatic ignorance here. Get comfortable.15:08
smcginnisOK. Depends-on doesn't really work with those, but at last it will be clearly on the radar then.15:08
jokke_ok, now I'm running like smcginnis adviced15:09
efried(Will wait for current conversation to die down, sorry to interrupt)15:09
jokke_smcginnis: ok good to know. well at least it has in the commit message the link to the patch we're waiting on15:09
jokke_efried: no problem. Just trying to get final release notes in to stamp down rc2 and call Train done :P15:10
efriedthat's WAY more important than my topic15:10
jokke_efried: unless you found something that breaks the world and we should hold :D15:10
efriednot even close15:10
jokke_so go ahead, we're waiting on zuul atm.15:11
efriedokay, it's about what you can/should store in glance15:11
efriedis it supposed to be just OS images15:11
efriedor could you hypothetically store arbitrary data blobs?15:12
jokke_nope, we really don't care as long as you're not trying to do conversion or introspection on it15:12
efriedI've got a downstream question about using it to store data files, like config files.15:13
jokke_we don't even check if you claim it to be raw and upload qcow15:13
rosmaitabut, an operator could write an import plugin that checks and blocks15:13
smcginnisI've had that same question before. There's definitely some that think glance is only meant for boot images. But really can be anything.15:13
smcginnisYou can store your Hello Kitty collection in it so you can get to it from all your instances.15:13
smcginnis:)15:13
efriedI want to say that that would be more appropriate for swift. But I guess I don't really know the difference...15:13
jokke_efried: I can see benefits of the immutability and possible additional metadata. As long as you don't try to boot up those config files (I think you can even make volume ot of them without anything blowing up) :P15:14
rosmaitasounds like you want glare :D15:14
efriedperhaps "glance can do anything swift can do, but is designed for big blobs and OS images" but "swift is for small data blobs"?15:14
jokke_efried: swift doesn't give you the immutability promise and only limited metadata, but true in more general usecase swift would be the way to go15:15
efriedtell me more about this "immutability promise"15:15
jokke_efried: so once image is created, that image-id in general always return you the same bits. There is no way (through the API) to change the payload15:16
jokke_with normal object store you can rewrite it and no-one really is on your way for that15:16
efriedso if I wanted to change an image, there's no way to get the same image-id associated with the new bits15:17
jokke_so if you put your configs into a tarball, store it in glance and your automation refers to that image id to get that exact tarball, you can be sure you got those exact configs15:17
rosmaitaright, you'd have to track it with custom metadata or something15:17
efriedgotcha.15:17
rosmaitabut, no matter what you store, nova will try to boot it if you ask it to :)15:18
efriedheh, right.15:18
efriedbut both glance and swift I could theoretically access from either the compute node or from within the instance, if I had the proper creds. They're both just APIs.15:18
rosmaitaso to answer your question, you *could* put anything into glance, but you *should* only put images15:18
jokke_efried: realistically no, there is even CVE about the very specific conditions where that might happen15:19
efriedoh, interesting.15:19
rosmaitaefried: and if you're using swift as the glance backend, would be better off just putting stuff into swift15:19
efriedI mean, I would assume I probably shouldn't give my instance access to the same images I give my compute node...15:19
jokke_efried: correct, about accessing your apis as long as your policies allow that15:20
jokke_like you can have set of glance-apis to your nova and cinder that can download images and your public facing nodes will not allow that but in general if you have one set of glance-apis with reasonable policies you can do pretty much all operations from anywhere you can access glance from15:21
efriedOkay, I think I have what I need for now. Thanks for the help, all!15:22

smcginnisrosmaita: https://review.opendev.org/#/c/687904/ has passed checks.16:45
timburkethis immutability discussion makes me think of one of the areas of active development for swift :-) we're working on a new form of versioning that more closely mirrors what S3 does, and i'm realizing that it may also satisfy some write-once-read-many feature requests i've heard over the years...16:50
smcginnistimburke: That sounds great.16:51
jokke_idlemind: you would need to define container format for it and make Nova/Cinder understnd it or use 2 images you create volumes from17:07
rosmaitajokke_: +A17:08
idlemindjokke_ thanks, i'm also looking at a guestfish thing to rework the disks into a single qcow17:08
idlemindjokke_ or is it more common to go the container format route when working with these wonderful vm appliance types17:09
jokke_idlemind: nope not really17:09
jokke_so if you have a way to smash them together beforehand it will make your lif much easier17:09
idlemindya i imagine it's becoming less of a problem as more and more stuff is going cloud native17:09
jokke_rosmaita: thanks, we should have RC2== 19.0.0 "soon" (tm)17:10
