Let me dump some topics we discussed there. </div><div># Sorry I thought I posted this somewhere early... </div><div> </div><div>Some concerns were raised about adding consul as a new core component, but we agreed with using it</div><div>as the initial implementation. There were some suggestions to rely on existing service records stored in DB</div><div>but we need some amount of work, to address the following points. </div><div>- Not all OpenStack services store service records in DB. (eg ceilometer)</div><div>- Even though some services store service records in DB, the available information there is not enough</div><div> - We have to maintain mapping between host and reachable endpoint</div><div> - Some services spawns worker and need endpoint *per worker*, and we need endpoint list for all workers </div><br><div>Random port assignment from range is another topic we discussed there, but we eventually agreed that</div><div>this is the required approach, mainly because it's hard to allocate port numbers for all services running in</div><div>a single node(required number of ports can be different based on services/workers/etc). So we agreed</div><div>that the proposed way to dynamically allocate available ports from the given range is a good solution.</div><div> </div><div><div>Also, LINE already deployed this feature in their production and it has been proven to work well in scale.</div><div>As we don't see any technical blockers at this moment, we agreed with moving forward with the proposed</div><div>architecture. There can be some improvement like adding the driver mechanism for cluster backend but,</div><div>we would avoid expanding our current scope, until someone is really interested in working on such topics. </div><div> </div><div>Finally we suggested updating the test plan and adding a devstack(at least single node) job in the gate</div><div>so that we can properly maintain the feature.</div><div> </div><div>Other people might have additional thoughts, but hope the above outcomes make the current proposal</div><div>more clear to all. </div><div> </div><div>Thank you,</div><div>Takashi </div><div><br> </div></div></div><br><div><div dir="ltr">On Sat, Jun 10, 2023 at 6:14 PM Masahito Muroi <<a href="mailto:masahito.muroi@linecorp.com" rel="noreferrer noopener" target="_blank">masahito.muroi@linecorp.com</a>> wrote: </div><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div><div style="font-family:Meiryo,sans-serif;font-size:14px"><div>Hi all,</div><div> </div><div>We have pushed the spec.
