I mean, yeah, that sounds reasonable. But I’m not actually, myself, connected with Docker. I’m just a random person who has invested a lot of time and interest into various emulation and virtualization stuff, and then worked at Google, and when I left, I didn’t have borg. So…
you might be able to find an official contact method to get in touch with someone, or possibly file a “bug” noting that documentation isn’t clear about --net=host outside of Linux. (The same problem is going to manifest in Windows as well.)
