I’d say your kids pc doesn’t need docker on it.
You can’t eat the cake and have it too. If you’re technically skilled to be using containers and virtualization, least you could do is file a helpful bug report.
I have nephews who are tinkering with Java and python, and I assume will be hitting docker at some point.
You're being incredibly nitpicky over a reasonable example of why PC is not as plug-and-play as a console. On a console, the game will work. On a PC, there are a lot of factors that may prevent it from working.
The entire "use a PC" premise is that the PC can be useful for gaming as well as for non-gaming uses, and the counter-argument is that those non-gaming uses can easily cause problems for the gaming uses. Docker is not the only example, tools like fiddler or wireshark or ghidra could cause problems. But heaven forbid that a gamer on hackernews be a tech enthusiast, right?
No, heaven forbid they want to tinker then complain but don't want to spend 5 minutes to file a bug report or follow the hacker way of actually figuring the issue out and proposing a fix.
And docker misconfiguration causing issues in unrelated services is one another reason why I'd suggest they have their own.
Same would go for any console, phone etc. You can’t just install stuff with known issues from 3rd parties, not file report with any diagnostics and then blame it on the platform. Would you blame iOS for a badly behaving app that makes it hard for the kids to use the iPad?
So again, for the huge number of people whose life involves technology there are a lot of things that can throw a wrench into that PC for gaming, and in those cases a console makes a lot of sense. It's a little odd to me that this bothers you so much; surely it is expected that consoles have a good usecase given their popularity?
xbox apps on Windows do not care about virtualization, in fact they probably can't - because xbox os is essentially a subset of windows as host and guest.
None of this is relevant. Maybe Docker's interface is "improperly configured" for the gaming use case. It remains a headache, and using a console is a viable solution that allows you to work with buggy instances of Docker without disrupting your gaming.
