This is probably a little bit off-topic but I find it very interesting that a majority of all the big
OpenStack clouds out there is running on containers based and a lot of them using “LOKI”
that was talked about so much in the OpenInfra Live Keynotes.

What I don’t understand is that, with all these limited resources, there is no joint effort
in the OpenStack ecosystem to solve the container deliverables issue and then just
have all deployments/tooling use the same.

Maybe that what they are doing though, using Kolla images… but then, wouldn’t they contribute more
and the below not be a problem *makes me wonder*

Sorry for off-topic loud thinking.

Best regards
