Even then, IMO, it makes too little sense. It would be a bit useful if non-used containers wasted a lot of resources, or if you could get an unlimited amount of them from somewhere.

But no, just creating all the containers you can and leaving them there wastes almost nothing, they are limited by the hardware you have or rent, and the thing clouds can rent are either full VMs or specialized single-application sandboxes.

AFAIK, containers solve the "how do I run both this PHP7 and this PHP8 applications on my web server?" problem, and not much more.
