Please do tell. Our containers never take less than 10 minutes to deploy (a single one).
I have app stacks that deploy a dozen containers over an hour because the orchestration takes time: signal the old containers to drain, pause for an app with a very long initialization time to settle, gradually roll traffic to the new one to let caches warm, and then repeat.
In both of these cases, deployment is a function of the application. There's nothing infrastructural that puts a time floor on things.
