Why? What do I stand to gain from using this? Marginal speed improvement in some cases and a lot of headache trying to debug it in other cases?
docker-compose offers an alternative. It doesn't offer any genuinely new functionality. It may work for you if you don't know how to use the other alternative, or the other alternative is inconvenient for you for some other reason, but if it's not, it's just an extra tool that you don't need.
This doesn’t sound right. You should be able to reset the password or at least start the process using the Apple support app or the website on the iPhone itself…setting is not the only way.
I omitted the step where the technician had me install the Apple support app as an alternative pathway to a password reset, but that had the same issue where a network connection could not be found regardless of being on WiFi or cellular.
