Guys from my team need to incorporate them. 15:21:16 indeed :-) if you have comments/questions, please feel welcome to put them on the change 15:22:00 So what do you think, how it looks like. Since this change should we support only docker containers managed by systemd? Or also managed by docker? 15:22:39 Hi team! 15:22:44 ohorecny: both first; I suggested to go in even smaller steps with refactoring itself being the first so that we can merge 1:1 functionality in new, more flexible, layout 15:22:49 hi Fl1nt 15:23:01 Sorry for the vanishing, I've been a bit busy lately :( 15:23:13 what's up yoctozepto ? 15:24:43 yoctozepto: So you think that both approaches should be supported? And user can choose ? 15:24:55 Fl1nt: we are in the middle of the meeting :-) 15:25:25 ohorecny: I think at least code-wise for a moment they should coexist so that we can weed out weird edge cases 15:25:31 aaaah forget about that TZ daytime switch fuu, thought I would have make it on time for once :( 15:25:36 sorry 15:25:56 Fl1nt: no probs 15:27:48 yoctozepto: aha, ok we went by that way that we are moving it under systemd management 15:28:10 https://docs.podman.io/en/latest/markdown/podman-generate-systemd.1.html 15:28:24 looks like you are using the start/stop approach 15:28:40 just wondering what are the merits of the --new approach 15:29:55 mgoddard: "please review the generated files carefully before using them in production" eh 15:30:14 I guess it would be nice to see how they look like 15:30:29 but we should nonetheless control the unit files ourselves like we discussed during the ptg 15:31:25 agreed, I'm just looking at what podman will generate for you 15:31:31 it gives you two options 15:31:43 by default it just starts & stops, as in the proposed patch 15:31:47 yes and this is how it is now for docker and merit is that in case of podman we will do it in similar way 15:31:57 but if you pass --new, it will create and destroy 15:32:21 both docker and podman could use either way 15:32:23 mgodard: genereting by using podman we already had implemented in that older big patchset 15:32:50 yes, I'm not suggesting we do that 15:33:22 I'm just saying, podman team has probably thought about this, let's see what they do 15:33:26 and they offer two options 15:33:31 so which should we follow? 15:34:15 is the destruction on stop? 15:34:25 yes 15:34:43 https://docs.podman.io/en/latest/markdown/podman-generate-systemd.1.html#generate-systemd-unit-file-for-a-container-with-new-flag 15:34:48 hmm, sounds like a way to ensure that containers are themselves stateless 15:35:19 IIRC ceph-ansible does it that way 15:35:43 yes and it works perfectly tbn 15:36:58 yes, that is good point, but it is in future now, when we introduce podman. As we discussed in PTG now we need to support docker with systemd 15:37:15 that's correct 15:37:32 and I've given you hints how to do it best code-structure-wise 15:37:42 ohorecny, you mean lifecycle of containers from systemd units or replace dumb-init with systemd ? 15:38:23 it's not necessarily in the future - you can use both patterns with docker and podman 15:38:24 Fl1nt: first option 15:38:24 Fl1nt: the first 15:38:38 ok thanks :D 15:38:55 perhaps the proposed approach is most similar to what we have today 15:39:04 mgoddard: let's maybe make it optional as well? 15:39:20 I want clean code change with the exact same behaviour except for systemd indirection 15:39:42 just a quick thought about that, as Ansible community.docker collection is able to really well manage containers lifecycle and that podman control containers from systemd units, is that really useful to integrate for docker? 15:40:10 Fl1nt: yes 15:40:21 exact same ansible code for both 15:40:51 ok 15:40:58 and we need to have more control/interaction with containers than just with the barebones 15:41:13 ansible module let you control everything 15:41:24 from volume to network and vars/etc 15:41:30 exactly like mgoddard said, it is not necessary, but in other case we will have much bigger change and "duplicated" code 15:41:37 Fl1nt: yeah, but at the cost of repeating a ton of stuff that we have customised for ourselves 15:41:42 yep unicity is best. 15:42:11 gotcha ^^ 15:42:15 ohorecny: one thing that would help: split the change into two parts. 1. refactor module to module_utils 2. make changes 15:42:25 cool initiative about podman indeed :D 15:42:46 IMO refactors should not change behaviour 15:43:06 Fl1nt: in that other way the patchset will look like this: https://review.opendev.org/c/openstack/kolla-ansible/+/799229 15:43:28 it was our first approach, but too big :( 15:44:20 yep, I kept an eye on it while being away of IRC ;-) 15:44:45 mgoddard: ok 15:45:15 Guys hinermar and halomiva do you agree? 15:45:35 Yes 15:45:38 they are mostly working on these changes 15:46:10 ok, so next step is do some refactoring 15:46:49 basically what I've commented about :-) 15:46:53 in case of any questions about review comments please ask directly in change 15:47:03 ok, any other Yoga things to discuss at this stage? 15:47:12 yoctozepto: right, thanks again 15:48:57 yoga? 15:49:08 Oh release name ^^ 15:49:13 sorry 15:49:39 ohorecny: you are welcome :-) 15:49:42 is there anything to discuss regarding "drop admin endpoints"? seems most people agreed to do it 15:50:39 so I'd just add a reno and it should be fine? 15:50:56 https://review.opendev.org/c/openstack/kolla-ansible/+/816164 for reference 15:51:27 let's do it 15:52:04 TM 15:52:29 and I agree wholeheartedly 15:52:52 though we could somehow help operators clean up 15:53:10 but it's easy to do via a simple script I gues 15:53:13 guess* 15:53:20 yeah, I was just thinking whether to add a script for cleanup that could be ran on demand 15:53:21 aaaah finally that blessed day where admin endpoints disapear !! 15:54:13 I'll try to come up with something 15:54:29 +1 for cleaning up 15:55:06 I suppose it might cause issues if we do it during the upgrade 15:55:56 yeah, should probably be a post-task 15:55:57 I wouldn't want to do it automatically, yes. but make it easy for operators as a separate step seems a good compromise 15:56:04 well, best to keep it as a helper script 15:56:18 ok, we are nearing the end of time 15:56:22 #topic Open discussion 15:56:27 anything really 15:56:56 I think this can be closed as Won't Fix, based on last meeting discussion https://bugs.launchpad.net/kolla-ansible/+bug/1554049 15:57:06 in Yoga - trying to move towards being able enabling the new system scope policies. 15:57:28 adrian-a: agreed from my side 15:57:31 so I've a discussion topic 15:57:43 since a bit of time now 15:57:45 at work 15:58:00 headphoneJames: and how's that going? 15:58:09 first pass 15:58:10 https://review.opendev.org/c/openstack/kolla-ansible/+/815577 15:58:53 its ready for comments 15:59:12 we're experimenting with an ansible method that gave us the ability in 1 repo to get both similar mechanisms than kolla/kolla-ansible 15:59:21 would you be interested in? 15:59:50 yoctozepto: The transaction only converts the config for the [keystone_authtoken] section, and not all the configurations for authenticating with other services through keystone. 16:00:37 Fl1nt: would be interested to take a look 16:01:11 headphoneJames: ack, sensible tradeoff 16:01:15 ok, out of time 16:01:21 thank you all for participating 16:01:27 #endmeeting
