| csatari | I'm doing my best :) | 14:06 |
| csatari | Okay, lets jump to the review part. | 14:06 |

| esarault | Nothing to add | 14:08 |
| csatari | If no comments lets move forward (I already have an action to generalize the synch service) | 14:08 |

| csatari | #topic Review of 5.3.2.12 Projects source side | 14:10 |
| *** openstack changes topic to "Review of 5.3.2.12 Projects source side (Meeting topic: review_of_dublin_edge_notes)" | 14:10 | |
| csatari | #link https://wiki.openstack.org/w/index.php?title=OpenStack_Edge_Discussions_Dublin_PTG#Projects_source_side | 14:10 |
| csatari | Here I talk about Quotas sometime. | 14:10 |
| csatari | That should be changed to Project. | 14:11 |
| csatari | #action (5.3.2.12) Change Quotas to Projects. | 14:11 |
| csatari | Can we have some inconsistency when projects are copied? | 14:13 |
| csatari | Most probably not, but I will check what data is stored in a project. | 14:14 |
| dpaterson | Sorry but when you say copy project are you referring to Keystone Federation creating shadow projects and users? | 14:15 |
| csatari | #action (5.3.2.12) Check if the data in a project can be inconsistent during the synchronisation (e.g.: if there are uuid-s there which are valid only olcally) | 14:15 |
| csatari | No, in this case there is a separate synchronisastion service doing the creation of projects and users. | 14:17 |
| csatari | And yes, I think we should describe the Keystone federation case also. | 14:17 |
| csatari | However these two alre alternatives on some level. | 14:17 |
| dpaterson | #link https://wiki.openstack.org/wiki/Keystone_edge_architectures#Several_keystone_instances_with_federation_and_API_synchronsation | 14:18 |
| dpaterson | csatari: that's the topic? | 14:19 |
| csatari | yes | 14:19 |
| csatari | What is described in the Dublin edge notes is "2.4 Keystone API Synchronization & Fernet Key Synchronization" without the fernet keys. | 14:20 |
| csatari | And the question is if we should also describe "2.1 Several keystone instances with federation and API synchronsation" as an alternative approach. | 14:21 |
| csatari | Or totally replace the API Synchronisation way. | 14:21 |
| dpaterson | csatari: looking, I was in Dublin but not in Edge track until just recently | 14:22 |
| csatari | In my personal opinion there will be no single option selected for these different issues, so the best would be to describe both of these alternatives in the wiki. | 14:23 |
| csatari | We can always delete if an idea turns out to be non working. | 14:23 |
| csatari | #action Add Requirements for the "2.1 Several keystone instances with federation and API synchronsation" option from https://wiki.openstack.org/wiki/Keystone_edge_architectures#Several_keystone_instances_with_federation_and_API_synchronsation | 14:26 |
| csatari | This ^^^ will affect all Keystone metadata related requirements. My plan is to describe a separate set of requirements for both of these options. | 14:28 |
| dpaterson | csatari: The Keyston sycronization service you are calling out is referring to the starlingx syncronization serivce correct? | 14:28 |
| csatari | StarlingX synsh service is one implementation of it. | 14:28 |
| csatari | When we defined it we did not know that WindRiver implemented it and we did not know that it will be open sourced under the name StarlingX. | 14:29 |
| csatari | We wanted to develop Kingbird further or start a new project to do this. | 14:30 |
| csatari | StarlingX synch service is also based on Kingbird by the way. | 14:30 |
| dpaterson | #csatari: From Monday's Edge meeting it looks like starlingx syncronization service is pretty dependent on starlingx specific bits | 14:30 |
| csatari | Yes. | 14:30 |
| dpaterson | #csatari: and kingbird looks pretty inactive | 14:30 |
| csatari | Yes. | 14:31 |
| csatari | But I would not like to drop the idea of an independent synch service. | 14:32 |
| dpaterson | csatari: This might sound old school but was using distributed LDAP discussed as a viable model? | 14:32 |
| csatari | No it was not discussed. | 14:32 |
| csatari | In some meeting Keysone people stated that LDAP is not an IDP, but something else. | 14:32 |
| csatari | This is all what I remember :) | 14:33 |
| dpaterson | csatari: with LDAP master/replicas you would get eventual consistancy for free | 14:33 |
| dpaterson | So instead of keystone database for auth realm use ldap (apache directory or openldap) | 14:33 |
| csatari | And can Keystone use LDAP as a backend database? | 14:34 |
| dpaterson | Yes | 14:34 |
| dpaterson | always been supported | 14:34 |
| dpaterson | as far as I know | 14:34 |
| csatari | And can we synch all needed Keystone data with this method? | 14:35 |
| dpaterson | csatari: could solve a lot of the discussion points without the need of an external syncronization service. | 14:36 |
| dpaterson | That I am not sure about | 14:36 |

| csatari | Okay. Let's add it to the Keystone alternatives list and start a discussion on the mailing lists. | 14:37 |
| dpaterson | I will take an AI to see what support there is, if it's auth only or if Projects/ACL/RBAC are part of ldap schema or does that data still have to live in relational database | 14:37 |
| dpaterson | It may allow auth only and depend on keystone database for everything else, not sure. | 14:38 |
| csatari | #action Add an alternative to the Keystone alternatives wiki for Keystone with distributed LDAP backend. | 14:38 |
| csatari | Okay, thanks. | 14:38 |
| csatari | #action dpaterson to check what support there is, if it's auth only or if Projects/ACL/RBAC are part of ldap schema or does that data still have to live in relational database | 14:38 |
| csatari | #action Start a mail discussion about the Keystone with distributed LDAP backend alternative | 14:39 |
| dpaterson | csatari: and under Keystone database replication, is this specifically Galera? Do we want to call out specific relational database distros that might work? | 14:39 |
| csatari | The description is technology agnostic, but if we can add in a note database distros what can actually do the work that is usefull information. | 14:40 |

| csatari | #topic Review of 5.3.2.14 Quotas source side | 14:49 |
| *** openstack changes topic to "Review of 5.3.2.14 Quotas source side (Meeting topic: review_of_dublin_edge_notes)" | 14:49 | |
| dpaterson | csatari: an issue with syncronization service vai API is that it needs to be in lockstep with any schema changes | 14:49 |
| csatari | #link https://wiki.openstack.org/w/index.php?title=OpenStack_Edge_Discussions_Dublin_PTG#Quotas_source_side | 14:49 |
| csatari | With API changes not (db) schema changes. | 14:50 |
| dpaterson | Yes, you are right | 14:50 |
| csatari | the issue with db synchronisation is that it should clockstep db schema changes. | 14:50 |
| csatari | An independent syncronisation service can support several versions of API-s. | 14:51 |
| dpaterson | yup | 14:51 |
| csatari | Even several VIM-s, but let's not go that far now. | 14:51 |
| csatari | Okay, lets start the wrapup. | 14:52 |
| csatari | #topic Wrapup | 14:53 |
| *** openstack changes topic to "Wrapup (Meeting topic: review_of_dublin_edge_notes)" | 14:53 | |
| csatari | #info Next Thursday we will have the Keystone testing meeting in the same time as this meeting, so we will skip the review. | 14:53 |
| csatari | #info Next meeting is 26.07.2018 16 CET | 14:54 |
| csatari | #info We will contiue from 3.2.15 Quotas receiver side | 14:54 |
| csatari | #info I try to organize a meeting to discuss about https://wiki.openstack.org/wiki/Image_handling_in_edge_environment but that will be in a different timeslot than this one as we are parallel to the Glance meeing and I would like to invite Glance experts. | 14:56 |
| csatari | That is it for today. | 14:56 |
| csatari | Have a nice day. | 14:56 |
| csatari | #endmeeting | 14:56 |
