Running 32-bit image on 64-bit host?

Summary: I am trying to create a base image from an Odroid Ubuntu image. I install the Ubuntu image on an SD card, then create a tgz from the entire root filesystem. I cat | import the tgz into a new docker image, and finally, try to run a bash shell from that image. The error I get from that is:

Error response from daemon: Cannot start container 03…1e: [8] System error: exec format error

Details:

  • Host computer is 64-bit mac, El Capitain
  • Docker version 1.8.3, build f4bf5c7
  • docker-machine: Linux default 4.1.10-boot2docker #1 SMP Mon Oct 12 18:36:49 UTC 2015 x86_64 GNU/Linux
  • Odroid img: http://odroid.in/ubuntu_14.04lts/ubuntu-14.04.3lts-lubuntu-odroid-c1-20151020.img.xz (Linux odroid 3.10.80-131 #1 SMP PREEMPT Thu Oct 15 19:53:29 BRT 2015 armv7l armv7l armv7l GNU/Linux)
  • TAR cmd: tar -cvpzf backup.tar.gz --exclude=/backup.tar.gz --one-file-system /
  • image creation: cat backup.tar.gz | docker import - odroidimg

I read all of the internet when it comes to the particular error above. There’s one enlightening thread on a docker github issue, but it doesn’t provide a solution. One guess I had is that the 64-bit docker-machine can’t run a 32-bit docker image. There are other docker machines here: https://github.com/docker/machine/releases. That doesn’t make a ton of sense, though, that I would need a 32-bit docker machine.
Any ideas? If I missed any details, please ask away.

It’s come to my attention recently that the problem might be trying to run an ARM architecture OS on an x86 architecture OS. Does anyone have any advice for trying to do that?

I am also facing the same issue. I have successfully ran the image but when I am checking the architecture, it is showing 64 bit.
Details:
Image:CentOS-5.5-i386
Docker version 1.13.1, build 092cba3 on Ubuntu 64 bit

Please Help ASAP
