I recently tried to setup calling gdb from docker as well, I also got
some weird errors. Eventually I'm able to make it work by disabling the
I/O separation (via "-inferior-tty-set") done by gdb mode.

Root cause seems that emacs allocates an inferior tty (for I/O
separation in gdb) for the *host*, which of course is not known to
docker gdb. I'm not really sure how it should be properly fixed.

This is my setup, I wrap around the gdb docker in a script:

This is the change I have to make:

P.S. I had hope on tramp remote gdb, but there are other issues... :(
