running x86_64 docker container on respberry 3

note: Deno does not support ARM (denoland/deno#2295), I tried to set up it with https://github.com/dbhi/qus, but it just threw random errors with the wrong executable and with qemu from apts but kernel panics

tl;dr: I'm trying to run the x86_64 deno docker container. On Raspbian I was compiling QEMU with -mcpu=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard CFLAGS. I got a working x86_64 VM with alpine. But it is too slow to run docker, and it ends with failed to start containerd: timeout waiting for containerd to start. In my opinion, it's because of 15 seconds timeout in this file. I try to rebuild Docker with other timeouts and check if it's working. But my solution is unprofessional and inefficient.

okay, firstly I ran my SSH session to raspberry 3 from @marwyk2003

pi@raspberrypi:~ $ cat /proc/cpuinfo | tail -n1
