Docker-compose is a orchestration tool that wraps around the inbuilt docker functions that are exposed like “docker run”, when teaching people a tool you generally explain the base functions of the tool and then explain wrappers around that tool in terms of the functions you’ve already learned.
Similarly when you have a standalone container you generally provide the information to get the container running in terms of base docker, not an orchestration tool… unless the container must be used alongside other containers, then orchestration config is often provided.
Probably, yes. Though I’d imagine they just won’t show you “foreign” plat on a given system. given the specific profit-sharing agreements with the closed platforms it’s impressive enough that DE have secured a deal that allows creation of paid assets without compensation on closed platforms, porting of currency is just so far out-there, the likelihood of it ever happening is negligible.
