Docker won’t run cross-platform containers any more. What gives?
Normally I used qemu-user-static like
sudo docker run --rm --privileged multiarch/qemu-user-static --reset -p yes --credential yes
This worked great. After some updates and upgrades, it didn’t work when I picked one of my projects back up.
I flailed for a bit, and finally decided to RTFM:
From: https://www.kernel.org/doc/html/latest/admin-guide/binfmt-misc.html
# mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc
Huh?
$ mount |grep binfmt
$
That’s not mounted.

That was it.
