Re: [openstack-dev] [Fuel] Overriding and removing VIPs from plugins

Guys, I suppose that any solution for the plugins merge ordering issue (either alerting about error or allowing user to manually set order) would be very helpful and much better then no solution at all (like we currently have). Maybe we should create a blueprint to not miss/forget about it?

Re: [openstack-dev] [Fuel] Overriding and removing VIPs from plugins

This is basically why I proposed to allow users to set per cluster priority for every enabled plugin. That would allow users to select results they need. Putting too many logic into checks whether two plugins are incompatible is error-prone and won’t stop anyone from shooting their feet. > 29

Re: [openstack-dev] [Fuel] Overriding and removing VIPs from plugins

I would not check that. We are not talking about installing browser plugins when users may not know what they want. Putting extra checks will create a more fool-proof but less configurable software. I’d vote for letting users shoot their feet using their plugins but making Fuel more flexible.

Re: [openstack-dev] [Fuel] Overriding and removing VIPs from plugins

Frankly, I have not though about how to deal with multiple plugins yet. However, what I think is that we must not restrict this too much and let users configure it more flexibly even if it allows to shoot one’s foot. Perhaps we can add a per-cluster priority for enabled plugins which users can

Re: [openstack-dev] [Fuel] Overriding and removing VIPs from plugins

> How are we handling this now for multiple plugins? OK, so right now we can only add VIPs to array, we can't remove them. So overriding would disable such possibility of adding VIPs from different plugins. But with [0] patch it will be still possible to add and to remove by providing empty

Re: [openstack-dev] [Fuel] Overriding and removing VIPs from plugins

Good idea, overally. How about multiple plugins? We don't have any sequence or priorities between them. What if one plugin assumes that VIP is present but other one wants to remove it? Aleksey Kasatkin On Thu, Jan 28, 2016 at 4:02 PM, Sergii Golovatiuk wrote: > +1

Roman, please provide more details on how VIPs are overridden. And how do you deal with multiple plugins. Aleksey Kasatkin On Thu, Jan 28, 2016 at 5:58 PM, Aleksey Kasatkin wrote: > Good idea, overally. > > How about multiple plugins? We don't have any sequence or

Re: [openstack-dev] [Fuel] Overriding and removing VIPs from plugins

Well, with merging instead of overriding, I believe, this problem with multiple plugins still exists, right? How are we handling this now for multiple plugins? Since VIPs is array I also vote for overriding, since merging it could be a pain (how do you remove existing element during array merge?).

Re: [openstack-dev] [Fuel] Overriding and removing VIPs from plugins

AFAIC, it is better to remove by name then. Otherwise, you do not know what VIPs you are removing. Another option - remove "built-in" VIPs using some specific expression. Anyway, you do not know where other VIPs (VIPs of other plugins) live so you cannot remove them this way. And the order of
